Review on 🔗 Dark Grey 41 Roller Chain Connector Link - Koch Industries 7541040 by Anferny Pineda

These #41 links are not an exact size for garage builder top chains like the standard Liftmaster/Chamberlaine/Craftsman size. Pens are too long. I got this to work using parts from other links for shims. The link now works properly. There is nothing wrong with this product. It's just not the right size for this application. Unfortunately I don't understand chain link sizes so I can't give you the correct size.
