Slotted Angle

Product was just what I needed and delivered on time. Thanks

Great pricing, free and RAPID shipping along with great communication; you can't go wrong with Preferred Doors! If the need arises I'll be a repeat customer for sure. L Kargol

Parts came in ahead of time. The parts were very good and very easy to install. Door works perfect and is quiet

The liftmaster repair kit was exactly what I needed. The parts arrived very quickly and the repair went well. I had enough in the kit that I could rebuild my old part so now I have a spare if ever needed. Thanks for the great service.

I have them on a 8 foot door. They stretch out to 71 inches with the door closed seem to work just fine. I do have a safety cable passing through the springs.
