The product was exactly what I needed and fixed the opener. The only issue I had was the original piece had threaded holes and the new one did not. I had to run out and get a few nits and bolts, but all-in-all it was an easy and effective repair.
These rail fasteners were better than the originals that were installed on my garage doors when our house was built. Preferred Doors shipped the replacements promptly and without any issues.
