Hi,
I need a new pivot block (or whatever you call the part that slides in the bottom rail) for a bifold mirrored closet door. Problem is that the corner block and rail on my door look different than the others I've seen on your website. It's an old Acme 17-4405 corner block, and the spring-loaded pin is in place, but it just drags on the bottom of the rail because I think the missing part must have broken before I bought the house. Do I need to replace the corner block, pivot block, pin, and rail all together?

Thanks for your help!
Bob

Acme was bought out by Stanley in the last century, and Stanley sold off many of the designs for their products. That makes it hard to go back in the past and find the replacement parts. I have narrowed it down to two possible guides, though, the 23-130 and the 21-174. Do you have another door that you can compare these guides to, to see if this is what you need?

There's a spring-loaded pin in the bottom of the corner block, so it looks like I just need the 21-174 roll guide. It looks like it will fit into the existing rail. Thanks Paul. Bob
