Vertical Track

The springs arrived here very quickly, and they worked like a charm.

Easy ordering process! Received in a timely manner! Perfect fit! Very reasonable price! Will order from Preferred Doors for future needs, and will recommend Preferred Doors to others!!

This hinge was the exact one we needed to fix our large commercial overhead door!. I didn't think I would ever find it as every where else we looked was out of stock and didn't know when they would get it back in stock. Very fast and efficient service.

Received order quickly and the bolts worked great for my project. I needed a fastener that looked like a rivet head but as a bolt.

GENIE 3850R works very well with my GENIE receiver #315390R2 that I have operating an old Chamberlin opener. The receiver was not included in the installation instructions but they were the same as the first (A) instructions you sent. You probably know all this but just in case not I thought I would comment anyway. Thanks
