Bolt-On

Very nice opener, easy to install and set up. Works quietly, nice slowdown of door prior to reaching bottom

Much higher quality than the original. Received wrong item first time. Right item was immediately shipped.

The complete gear kit was exactly as described and included everything needed to overhaul a worn out assembly. The link to the YouTube video was indispensable. The only small glitch was that the video didn't emphasize was that the plastic sprocket dust cover mounting holes require that the assembly be installed so they line up front to back. I put my opener all back together only to find that the dust cover holes were not where they needed to be. Had to fabricate my own little dust cover from a plastic cup and double stick tape it to the unit. Not pretty but it does the job. Small complaint.

It's right during the holidays, and I needed to order an essential replacement part (called a coupler) from Preferred Doors for my Genie garage door opener. The part was placed into the USPS mail the same day that I placed the order, and arrived here in So Cal only three days later. Preferred Doors had the part in stock, at a great price, and also provided pretty amazing service, even beating the shipping time quoted by a competitor on Amazon Prime.

A+ Fast Shipping, Great Price, Described as advertised.
