Belt driven garage door openers offer a prime level of noise reduction if you want a silent environment in the garage. While common chainlinks will rattle during use, the smooth performance of a belt dampens noise as the garage door slides up and down. Using a 3/4 motor, the Genie SilentMax 750 will easily tackle any typical garage door while keeping the environment quiet and comfortable while in use.
Once the shaft, springs, and center bearing plate come down and lay on the floor, the old springs should be easy to get off and new ones slid on and assembled. Two bolts hold the center cones to the center bearing plate. The bearing on the center plate can be oiled while it is exposed from having the springs off. At this point it is a relief to be working with inert parts while standing on the floor rather than energized parts while up on the ladder. You might think it would save a little time to replace the spring with the shaft left up on the wall, but I found it was easier and safer to lower the works down to the garage floor first.

Speed of a thrown winding bar:: The springs, being in balance with the door, effectively are able to launch a typical 150 lb door at 10.6 mph speed. An 18-inch long by 1/2-inch diameter steel winding bar happens to weigh about 1 pound. Since momentum is conserved, this 150:1 ratio in weight of the door to the winding bar means the fully-wound springs could potentially throw a winding bar at 10.6 mph * 150 = 1590 mph = 2332 ft/sec, assuming the energy were perfectly coupled and transferred. If the energy transfer were only 1/3 efficient, this would still be the 800 ft/sec speed of a typical pistol bullet. Except it is a foot-and-a-half metal spear, not a bullet.
Angle iron provides a stronger installation and reduces vibration, which helps extend the opener’s life span. In an unfinished garage, attach the angle iron directly to the face of a joist with 1-in. lag screws. For finished ceilings, attach angle iron along the bottom of a joist with 3-in. lag screws. Hang the opener using two more lengths of angle iron and nuts and bolts. Use lock washers or thread-locking adhesive to keep vibration from loosening the nuts.

While a new coat of paint can go a long way in improving the look of your garage door, the truth is that door design has come a long way in the years since garages were first installed in homes. Not only are newer doors more in line with current fashion trends, but they are also better sized for today’s cars. A new, contemporary door is a great way to get an immediate boost on the value of your home.
Great service all around! Friday night issue with other service company… Aaron’s didn’t turn me down in resolving the fact that I had NO use of my door until Monday. They sent a very well experienced technician on Saturday morning. He was prompt, explained everything very well, advised on next service needs (without being sales-y) and did an awesome job! Thanks again!!!
Uncentered center bearing plate: The center bearing plate need not actually be in the center. It doesn't much matter where it is, since the purpose of the bracket is to anchor the spring ends. This anchoring must be secure, since all the torsion is held together at that point. On a stud-framed wall, this bracket may be placed over the stud closest to the center rather than exactly at the center of the door opening.

In the United States, the Consumer Product Safety Improvement Act of 1990 required that automatic residential garage door operators manufactured on or after 1 January 1991 conform to the entrapment protection requirements of the 1988 version of ANSI/UL standard 325.[11] A requirement for redundant entrapment-prevention devices was added in 1993; such a system can use an electric eye, a door edge sensor, or any other device that provides equivalent protection by reversing the travel of the closing door if an object is detected in its path.

When you’re thinking about replacing your garage door, there are many options to consider. Picking out materials and styles is sometimes stressful for homeowners. Neighborhood Garage Door Repair has some helpful tips on choosing the right material for your door. Garage Door Materials Manufacturers offer different materials when it comes to designing a garage door. […]

When picking the best garage door for you, a good place to start is with material type. Most garage doors are made from either wood, steel or fiberglass. These three materials are strong, durable and each have their unique benefits at various price points. In order to pick the perfect fit for your home we have developed the DoorView® garage door designer. This interactive visualizer tool helps you design your dream door and allows you to see how it will look on your home with just the push of a button. You can also try it on your Apple iPad and Android devices.
Spring rate, torque, and lift: The spring rate K for these measurements is π*28.5*10^6 * (0.273)^4 / (32 * 140 * 1.72) = 64.5 IPPT. Applying 7.5 turns on this rate will yield a torque of 7.5 * 64.5 = 484 in-lb, which on the 4-inch drums (2-inch radius) yields a lift of (484 in*lbs)/(2 in) = 242 lbs. Again we find good agreement with the approximate door weight of 238 lbs.

Since 2015, we’ve tested a variety of devices such as smart locks, video doorbells, DIY home security systems, thermostats and more. We use these testing experiences to inform our evaluations of other equipment. As time and resources allow, we occasionally test new types of products, but there are still some circumstances where we’re unable to conduct in-house tests. When testing isn’t possible, we conduct thorough research using the same standards we apply to our in-house tests – this is the case with smart garage door openers. We’ve reviewed garage door openers since 2011. 
Mechanical garage door openers can pull or push a garage door with enough force to injure or kill people and pets if they become trapped. All modern openers are equipped with “force settings” that make the door reverse if it encounters too much resistance while closing or opening. Any garage door opener sold in the United States after 1992 requires safety eyes—sensors that prevent the door from closing if obstructed. Force settings should cause a door to stop or reverse on encountering more than approximately 20 lbs (9.07 kg) of resistance. Safety eyes should be installed a maximum of six inches above the ground. Many garage door injuries, and nearly all garage door related property damage, can be avoided by following these precautions.
Cost was $88 for 2 pairs of springs, plus $21 shipping. (I had to order 2 pairs to meet the $50 minimum order.) They came with new cones inserted as shown at that price, so I didn't bother trying to remove and reuse the old cones to save a few dollars. The cones are quite difficult to remove from old springs and to insert in new ones, and the spring supplier will have the right tooling to do that easily. That was the best price I could find on the Web at the time, and didn't seem out of line with what parts like this might cost at at the building supply (if they only sold them). Contractors buy these much cheaper in quantities; they're just an ordinary high-carbon steel wire turned on a winding machine. I also found Web sites asking a lot more money, obviously trying to cash in on search-engine traffic from do-it-yourselfers. Others report that some local dealers sell springs at retail, but at a high price that eliminates any economy versus having them installed.

The history of the garage door could date back to 450 BC when chariots were stored in gatehouses, but in the U.S. it arose around the start of the 20th century. As early as 1902, American manufacturers—including Cornell Iron Works—published catalogs featuring a "float over door." Evidence of an upward-lifting garage door can be found in a catalog in 1906.[4]
If your garage door is opening slowly or making a lot of noise, the problem may not be your opener. So before you buy a new one, check for broken or wobbly rollers and brackets. But don’t replace the bottom roller bracket yourself—the cable attached to it is under extreme tension. You’ll need to call a pro. If you’re replacing the rollers, get nylon rollers. They operate quieter than steel rollers and cost only a few bucks more. Next, check the torsion spring (mounted on the header above the door opening) to see if it’s broken. When one breaks, you’ll see a gap in the coils. You’ll need a pro to replace a broken spring.
