Garage Door Safety
According to the Consumer Product Safety Commission, 4 children are crushed by garage doors each year.
Proper installation, maintenance, and testing is necessary to keep the garage a safe working environment. An opener that is not installed properly could result in a serious, and in some cases fatal injury.

is proud to offer you these easy to follow tips...
1. READ AND FOLLOW ALL INSTRUCTIONS
IF DOING A SELF INSTALL.
(We strongly recommend using a qualified service installer)
2 . Remember to treat your garage door remote control like a key.
Do not leave it in your car where it can be seen - hide it in the console, glove box or somewhere else in your car, but don't leave it on the visor where it can be seen.
3 . Never stand or walk under a moving door! Do not let children play "beat the door." It is very dangerous and can result in serious injury or death. Adults should set a good example.
4 . Teach your children about the garage door safety.
Explain the danger of being trapped under the door. Never let children play with or use transmitters or remote controls - always keep them out of reach. Children should be supervised in and around the garage door area.
5 . VERY IMPORTANT - The push button wall control should also be out of reach of children (at least 5 feet from the floor) and away from all moving parts. Mount and use the button where you can clearly see the closing garage door, and keep the door in sight until it completely closes.
6 . TEST MONTHLY - The garage door MUST reverse on contact with a 1-1/2 inch high object (or a piece of two-by-four lumber laid flat) on the floor. If the door doesn't stop and reverse after contact with the object, disconnect the operator and use the door manually until the operator is replaced or repaired by a qualified technician.
7 . An improperly balanced door increases the risk of severe injury or death. Have a qualified service person make repairs to cables, spring assemblies, and other related hardware.
8 . Garage door springs, cables, brackets and other hardware attached to the springs, are under very high tension and, if handled improperly, can cause serious injury. Only a qualified professional or a mechanically experienced person, carefully following the manufacturer's instructions should adjust them. The torsion springs (the springs above the door) should only be adjusted by a professional. Do not attempt to repair or adjust torsion springs yourself.
9 . A restraining cable or other device should be installed on the extension spring (the spring along the side of the door) to help contain the spring if it breaks. Never remove, adjust or loosen the screws on the bottom brackets of the door. These brackets are connected to the spring by the loft cable and are under extreme tension.
10 . Make sure you opener has a reversing feature.
If a reversing feature is not present, it should be replaced. Garage door openers manufactured after January 1, 1993 are required by federal law to have advanced safety features which comply.
11. While on vacation, unplug the garage door opener unit, or use a wall console security switch, which is an optional accessory to most openers.
Garage Door Springs
Oil Tempered Spring Galvanized Torsion Spring
Both types of wire, oil tempered springs and galvanized hard drawn springs, are made from the same basic raw material: a high-carbon steel rod which is drawn down to a specific wire diameter. The simple explanation of the drawing process is that the wire is stretched to a specific wire diameter by running the rod through a series of progressively smaller dies, coated with a lubricant until the required diameter is achieved.
Galvanizing is the process of applying/ bonding a zinc coating to the surface of the wire. In the case of galvanized wire for garage door springs, the galvanizing process is done prior to drawing. You may have heard the term drawn after galvanizing or DAG. This is the process currently used to manufacture galvanized spring wire for garage doors.
Oil tempering is an additional step in the process after the wire is drawn in which oil is used to heat-treat the wire to give it certain properties. The wire is heated to a very high temperature in excess of 1500 degrees Fahrenheit; then cooled rapidly or quenched using oil, and then reheated again to a very high temperature. This process is intended for wire used in springs that are subjected to static loads or relatively infrequent stress applications, according to ASTM. This is meant to distinguish garage door spring applications with relatively low cycles from valve spring wire for automotive applications, which are very high stress, high-cycle springs for example.
Historically, the garage door industry used torsion springs made of oil tempered wire that conformed to ASTM 229 standards which detail, among other things, tensile strength ranges by wire size. This wire falls into two categories: Class I and Class II. The difference is that Class II has higher tensile ranges than Class I in the same wire size. At one time, the garage door industry had a unique classification called Overhead Door Quality. It was a hybrid between Class I and Class II. Although some wire mills still supply Overhead Door Quality oil tempered wire, today the vast majority of the industry sees Class II.
Oil tempered springs have excellent performance properties for garage door torsion springs. A significant negative aspect of oil tempering material is the oil residue from the oil tempering process. This residue stays with the wire even after the spring has been coiled and heat-treated. This requires the installer to be very careful not to leave handprints on the garage door and walls after installation or else face an unhappy homeowner. This oil residue has no rust-inhibitive benefits, therefore oil tempering springs, as any unprotected steel product, will rust rather quickly, presenting yet another challenge to the hard-working door installer carrying springs in his service truck.
Some door manufacturers began to require the application of a painted finish to their residential torsion springs, thereby providing a clean spring surface as well as some degree of rust protection. As the average residential torsion spring weighs about 10 pounds, this process was, at that time, very labor intensive. The timing was perfect to present a product that provided the benefits of a clean, rust-inhibitive coating without the additional labor. Galvanized springs appeared to be the perfect solution. This wire was a lead-patented hard drawn wire, galvanized to solve the residue and appearance issues. As an added benefit, according to press releases from that time, it also provided superior cycle life in comparison to springs made from oil tempering springs.
Galvanized hard drawn springs look great and usually are nice and shiny when installed. Springs manufactured from oil tempering wire and coated after coiling look great as well, thanks to the development of rust inhibitor coatings that offer a clean, non oily surface and a brilliant shiny, black finish. Its important to mention that galvanized hard drawn wire has a limited shelf life. Over time, the finish on the galvanized hard drawn wire will begin to dull, and a white, powder-like substance will appear on the surface. This is known as white rust and is oxidation of the zinc coating. Springs made from galvanized hard drawn wire will exhibit this characteristic over time and will not maintain their shiny appearance indefinitely. Springs manufactured from oil tempering wire, even with the newest coatings available to the market, will also oxidize over time, although the appearance of the oxidation does not seem to be as apparent as that of the galvanized hard drawn.
The Facts About A Single Spring Vs Double Springs:
A single spring normally lasts 5-7 years. A single spring causes more wear and tear on the end plates. In the future when the spring breaks you have to lift the full weight of the door to get your car out. Using a single spring is a generic spring that works with lots of weights of doors. If your door is heavy, they just crank more turns on the spring to balance the door. The more turns on a springs reduces the life of the spring.
Double springs normally lasts 7-10 yrs. The two springs cancel each other out and does not have the wear on the end plates. Having two springs make more sense because in the future when one of the spring breaks you can lift the door up and you only have to lift half of the weight of the door because of the spring that is not broken. This is really important, because you never know when one spring might break. To achieve the exact weight of your your garage door. They can install one spring on one side and another spring on the other side that way they can get your door to balance just right.
From years of experience, we can confidently say that Oil Tempered Spring is tried and true when it comes to the manufacture of garage door torsion springs. The oil tempered spring holds its tension better than the Galvanized Steel Springs. This is very important to people who have garage door openers. Then the door becomes heavy and the garage door opener works harder to lift up the door which reduces the life of the garage door opener. This also causes the garage door opener to become louder because it is now working harder to lift the door.
