100 Pcs Rubber Door Silencer, Metal Door Anti Collision Silencer Heavy Duty Rubber Hinge Outlet Door Silencer 1/2 Inch Diameter for Metal Frame

Worked as advertised, good product

They work on commercial metal doors as replacements.

They work as expected and are easy enough to put in place

They work just like they're supposed to. The only trick was that the last set I installed years ago must have been something like butyl rubber, so they had turned into a kind of hard and dried putty-like material. I used one of those paint scrapers that has a triangular point on one side to sort of break those out and clean up the hole and surface a bit, and the new ones popped right in. In some cases it helps to give it a bit of a twist as you push it in. We'll see how they last, but the silicone design may hold up better than other forms of rubber. They're so cheap in any case that it doesn't much matter. I may have to adjust one of the door pistons because when the silencers get too old to work, someone will often slow the door closer so much that it won't automatically pull shut and lock when the fresh bumpers are installed.

Great replacements
