Garage Doors – A Brief Tutorial on Garage Door Safety and Installation

As a door expert witness, I am called upon many times a year to evaluate garage door injuries. Garage doors come in many shapes and sizes. Their functions range from basic security of an area to cosmetic concealment. Most doors can be broken down into a few basic styles or categories. Typical modern garage doors for residential applications tend to be predominantly of the overhead sectional variety. That style of door comes in many configurations, materials, levels of insulation, and a wide range of appearance possibilities. They are available as a prefabricated kit, or built as a custom design to complement the dacor of any building. Commercial warehouse type installations often dictate higher security requirements. A good choice for this security type of door is the “roll-up” style that resembles a roll top desk type of door. This door can be manufactured with a variety of materials that can be as strong as the adjacent walls, making forced entry through this opening very difficult. Other common commercial installations include light weight aluminum single or sectional panel doors. These doors function more for closing off an already secured area than for assuring point security.

In the past, the biggest concern with operating an overhead garage door was the potential risks associated with the springs used for balancing the door weight. Pre mid 1960′s garage door installations typically relied upon a pair of stretched (tensioned) springs to assist the operation of the garage door pivoting hinges. These springs became loaded (tensioned) as the door was moved into the closed position. Unloading (releasing) of the stored spring energy occurred as the door was opened to the horizontal overhead position. One of the most dangerous aspects of these spring systems was that after a period of time, often without any maintenance or inspection, the points of attachment of these springs would rust or become weak. This weakening of the springs or points of attachment would often lead to an inadvertent explosive failure flinging the broken spring components across the garage, embedding the spring or steel components into the garage walls, cars or other items in the path of travel. Unfortunately, sometimes people were in the path of travel of these explosive occurrences. As these springs failed, as an attempted safeguard, some manufacturers devised a “caging” system for the springs. These cages were retrofitted onto the stretched springs in an attempt to capture the parts that would release if a failure occurred. While these caging devices were helpful, they were not completely effective. Some of these spring devices are still in use today. Whenever this condition exists or the quality of garage components are questionable, a qualified professional service technician should be consulted.

In response to the inherently dangerous old style garage spring issues as above, a newer and safer system for opening the overhead garage door was created. The idea was to transfer the load or weight of the door via a cable and pulley system to a vertical rod now equipped with a torsion (twisted) spring. This type of spring is installed with specialty hardware and bolts to a fixed plate at one end, while the entire spring is installed around a horizontal pipe. This load balancing device is normally installed directly over the header of the garage opening. Using appropriate cables, connectors and pulleys, the weight of the garage door is transferred into the torsion spring system. The difference between the old style stretched spring and the newer torsion spring is the way that the spring energy is stored. With the old style stretched spring, the energy is stored and released by pulling on the spring or returning the spring to its un-stretched condition. With a torsion type of spring, the energy is imparted or removed by rotating the spring clockwise or counter clockwise depending upon the direction of usage. With professional installation, the complete loading of the torsion spring is controlled by the garage installer, and is determined by the weight and size of the garage door that it is operating. When this type of torsion spring fails, it remains attached and intact to the location on the horizontal control rod where it was mounted. I have not heard of or seen any torsion spring fly across a garage, creating injury from failed components as with the stretched older style garage door springs. This is not to say that injuries have not occurred with the torsion style spring. The installation of this type of spring is generally safe when left to a trained garage door installation professional. Severe and serious injuries have occurred when untrained, unqualified individuals have attempted to install or service this type of spring. In most installations, a warning tag is left attached adjacent to the torsion spring when the garage door is installed. This tag warns of the danger associated with the stored energy of this spring, and alerts untrained individuals to not attempt any repair, adjustment or to even touch the spring and associated hardware. When the label that should be attached to this spring becomes damaged, is removed or tampered with, it is important that a new warning label be reattached immediately to show the dangers of this spring tension

Garage doors can be operated manually (by hand), as well as automatically (by power assisted motor). In both cases, the proper operation of the garage door is determined by the proper balancing of the garage door weight, springs and related component hardware. An automatic power assisted motor cannot overcome an improperly balanced garage door. The weight of all garage doors is normally deceptive. Due to the fact that a properly functioning door appears easy to open and close, many users do not realize the combined overall weight until springs fail to assist the door in its operation. In all cases, regardless of the type of garage door, the entire system of hinges, track, hardware, and door opener work as a team. Problems with misalignment, shifting, or jamming can lead to problematic operation of a door. Counter forces imparted to a garage door, not engineered into the components, can lead to injury. Inappropriate maintenance or complete lack of maintenance has lead to severe bodily injuries. Forcing the operation of a garage door, when one or more components have become damaged or broken has lead to serious bodily injuries. In all cases, maintenance is a crucial and important aspect of proper operation of all door systems.

In contrast to an overhead type of garage door, be it sectional or single panel, roll up doors have a totally different type of operating system. When these doors are used, they can be concealed in an overhead or under mounted trough. These doors operate similarly to a roll top desk door except for how they are stored when not in the closed position. They normally coil as they are retracted, and require significant gear trains to reduce the effort required to move these doors up and down into position. Often the forces needed to move these roll up doors require a reduction type of transmission that allows a very heavy door to be operated effortlessly. These doors can be chain driven either manually, or can be automated using electric motors. Roll up doors require more frequent evaluation and servicing than a standard overhead garage door. The tracks that are mounted vertically on both sides of the garage opening need maintenance and cleaning more frequently, and are often blocked by foreign obstructions or damaged by collision of some type. These roll up doors are often held open by some type of ratcheting action. Proper balancing of these doors is often more important than an overhead type of door, as the weight of these type of doors is normally much greater than an overhead door.

The Importance of Choosing a Good Garage Door Hardware

Garage is one place that should have a solidly built garage door hardware as it is an essential part of any household and is the vital feature that establishes its safety. Or if you happen to be building a new house ensure that the door to the garage is well chosen and has the appropriate hardware.

When choosing a door and the accompanying hardware it would ideal to consult your architect or seek the advice of experts who will be able to help you choose the best hardware that will suit your requirements and your budget as well.

Typically garage door hardware is available in various materials, and the selection should be made after taking into account all features with regard to the garage. The common materials that are generally used are aluminum, wood, and steel, but there are other materials like fiber glass.

Typically steel is the most popular, as they are durable and much stronger than any other material and provide utmost security to the interiors. But those who are more conscious about looks would prefer wood.

Garage door hardware also includes the installation of proper threshold and seal as they play a major role in the maintenance of the garage. If you find that there is grease or debris under the garage gate, then it implies that the garage threshold needs refurbishing. Even the seals may become fragile and misshapen and will need to be replaced. There is no point in having an excellent door with great mechanism if the threshold and seal are not of good quality.

The other add-ons that you will require for the hardware will be the rollers, the hinges, the cables for the spring, etc. Remember that choosing the right garage door hardware may not be a very technical aspect, but ensure you do your home work well before you finally settle on one.

Remodeling – Color Change on Cabinet Hardware

What color to change cabinet hardware door knobs to remodel? Wow that’s a tough question. There are so many options available it can confuse anyone. Color, shape, size, style, finish – there are so many options available. Where do you start? No one wants to end up spending a truckload of cash for a cabinet refinish just to end up with ugly drawer pulls, knobs, and hinges. Let’s look at what options are most commonly available to you.

You have help available. The home improvement store will be more than happy to sell you just the right hardware you need. So why not grab a digital camera and take some pictures of the kitchen. Do some close ups of the doors as well as wide angled shots that show the whole kitchen?

Bring the camera to the store with you and ask to speak to a cabinetry sales consultant. They’ll be able to narrow down what styles will work for you. If you have an ultra-modern kitchen then you can immediately rule out an entire class of old fashioned hardware. See, things are already getting simpler.

The consultant should have helped you narrow down what style and color you’re looking for. For instance if you have a rustic rough cut wood cabinet you can go with one of two options.

The first option is to go primitive and use a natural wood handle the same as the cabinet wood. This will help keep a nice uniform look to the cabinet. It will show off the wood it self without drawing attention to the door hardware.

The other option is to go big and heavy with some black cast iron decorative work. Decorative cast iron will accentuate the cabinetry and help make it stand out as a show piece of the room.

What would you use for an antique glass paneled cabinet though?

Once again you have two main options.

The first option is to go with a rather dainty enameled knob. This helps pull together the whole antique theme of the cabinet. Then enameled look will draw attention to the door and also to the windows.

Another way to get the same feel, but for a bit cheaper price, is to go with glass knobs. Glass can reflect the light and make the cabinets shine. It will help establish the bright airy look you’re going for in the kitchen.

The final example is ultra modern preconstruction cabinets. These typically are a single flat color. To keep this sleek look you’ll want to go for recessed door hardware that will match it. By going recessed you won’t have any protrusions that take away from the long straight lines of a wall of modern cabinets.

What color to change cabinet hardware door knobs to remodel can be a tricky question. It all boils down though to personal taste. Home improvement is a gigantic business and there are all sorts of vendors out there that will be more than happy to provide you with just the right hardware to make your cabinet look like new.
