How to Support End Bearing Plates

Friday, October 13th, 2017 at 6:12 pm by Dan Musick

For shafts to turn properly inside the end bearings, the end bearing plate must remain plumb. If the plate is not supported it can lean, causing the bearing or shaft to wear. Often a worn bearing will wear completely through the shaft causing the shaft and drum to drop and the garage door to become out of level.

Many of the bearing plates are flat and the horizontal track angle was not strong enough to support the plate, so additional angle was added. Here the bottom of the angle is bolted to the horizontal angle and the top is wedged into the jamb.

Another way to support a flat end bearing is the top of the flag bracket. On this door the drum was scraping the top of the flag bracket.

The simplest solution, without adding any angle, was to re-position the end bearing plate so the flag bracket supported the outside of the end bearing plate. Doing this may require moving one of the drums.

Another way to support a bracket on 12″ radius tracks is by wedging angle between the horizontal angle and the top of the flag bracket.

The support angle can also be bolted at the top and bottom.

One of the better inventions in the door industry for residential doors was the spring anchor bracket with the added edge that can be secured to the jamb. On 12″ radius tracks the top of the flag bracket supports the bracket. The top hole allows for an optional bolt but this is not normally needed on 12″ tracks if the cable drums are properly installed touching the races of the bearings.

On 15″ radius tracks, however, the top of the bracket must be secured. Normally a single 5/16″ X 1 5/8″ lag screw is needed, as shown here.

Sometimes additional support is needed as you see here where the top edge did not reach the jamb.

On one job a recessed I-beam prevented the normal installation and angle was run from the horizontal angle to the board on top of the beam.

Here is another solution where angle was added because the top edge of the bracket was above the header.


Long Life Extension Springs

Friday, September 8th, 2017 at 4:48 pm by Dan Musick

Garage door extension springs stretch as the door closes and contract as the door opens. Also designated “stretch springs,” these usually mount above the horizontal tracks, but sometimes they extend beside the vertical tracks.

Over the years there have been requests for better springs because customers’ existing springs have not lasted as long as they had hoped. Because of this we have begun offering longer life extension springs which last about three times longer than the standard springs.

We achieve longer life in our design by using bigger wire and larger inside diameters engineered to maintain the same pull. We also use clipped ends to extend the life. Open loops and double loops are heated before bending the ends; this often fatigues the metal causing the spring to break prematurely on one end.

One additional factor in producing longer life extension springs is that we have the springs produced in the U.S.A. and only with American made steel. Because of inconsistent quality control standards in China springs made there will often work for a while, but before long the springs don’t contract as they should, the door gets harder to lift, and often the cables come loose and prevent the door from closing. The metal doesn’t fatigue; it simply looses its tension.

Besides the Chinese manufacturers beware of companies who offer long life or 25,000 cycle springs based on what a supplier may say about their springs. A while back I ordered some of the springs from a supplier and I was surprised to discover they were the same standard cycle springs as offered by other suppliers.

All of the springs come in 10 pound increments and they are in stock for same or next day shipping. For questions please contact us.


Warehouse Manager & Personnel Manager Wed

Way to go, Neal and Jorie! Congratulations! We wish you all the best as you begin your lives together.

Neal and Jorie, October 21, 2016.

Neal has been a huge help since we were working out of our garage not many years ago; now he has his hands full with a large warehouse full of parts to inventory and ship.

Jorie has helped us part time since September of 2015 as she has finished her education and prepared for her wedding. She’s been a tremendous help performing a variety of skills, including the completion of our first employee handbook and helping us set up employee reviews. She’s also advised us on a number of other personnel issues.

She’s a great worker and she would be a valuable asset for a larger company who can use someone full time with her education and skills. In May of 2016 she received her Master of Arts degree in Industrial/Organizational Psychology from Elmhurst College. You can discover more about Jorie in her resume.

Spring Is Here! A Few Checks Are In Order

Garage door buckes can be corrected

Meteorological Spring made its glorious arrival this past Monday, and Daylight Saving Time will kick in next Sunday the 14th.  What kind of winter has it been around your house?

With garage doors getting a workout all winter in the “car protection” mode, it is possible that you may find a few pieces of hardware (screws, nuts, bolts) strewn on  the front half of your garage floor.  After picking them up to avoid a flat tire, have a look around on the door to see where they came from.  If you can’t make out from where, how is the garage door functioning lately?  Run a cycle on the door and watch.  If you observe buckling or strange noises while in travel, you may need a low-involvement repair.  Call Dan at DDM and get confidence, with knowledgeable advice.

This advice may necessitate a repair, or simply a lubrication.  But if you get it addressed now, you can save trouble and expense down the road.  Have a GREAT spring!

(Warning:  As always, be careful around garage doors and their parts, and call a professional for the work if you have any doubt about your ability to service them safely).
