Pamex DD08-11 Spring Crash Chain with Vinyl Bright Chrome Finish

Pamex lists the DD08-11 as a residential item, so it suits houses, apartments, and light duty interior use rather than high traffic commercial doors. For a heavier commercial door, look at a chain crash stop like the Trimco 4048 Series instead.

It's a chain door stop: one end mounts to the door, the other to the frame or jamb, and the chain limits how far the door can swing open so it can't slam into a wall or fixture. The Pamex DD08-11 uses a solid twisted chain with compression springs at one end, so the springs absorb the shock at the end of the swing instead of the screws taking it. Useful on doors that catch wind or get pushed open hard.

Yes, wood screws are included, so it's ready to mount into a wood door and wood jamb or frame as supplied. If you're fastening into metal, masonry, or hollow core, you'll need to source the appropriate fasteners or anchors yourself.

It's built to ANSI/BHMA A156.16, the standard covering auxiliary hardware such as door stops and holders. That's the only standard stated for the DD08-11.

Both are chain type crash stops that limit door swing. The Pamex DD08-11 is a residential grade unit with a gray vinyl covered twisted chain, compression springs at one end, and wood screws in the box. The Trimco 4048 Series is the other chain crash stop option, offered in the 603 finish. Pick the Pamex for house and apartment doors; consider the Trimco where you want the Trimco series on a spec.

A floor or wall stop halts the door at a fixed point and takes the impact at the stop itself. A crash chain like the Pamex DD08-11 catches the door at the end of its travel through a chain anchored to the jamb, with compression springs taking up the shock, so nothing has to be mounted to the floor or the wall behind. Chains are the choice when you can't drill the floor or there's no wall in the right spot, and when you want the swing limited rather than the door held.

For a fixed-finish match, the Trimco 4048 chain crash stop is offered in 603 finish only, so there is no finish selection to make. The Pamex DD08-11 is a bright chrome vinyl crash chain, so specify it when bright chrome is what the other openings carry.

No. The DD08-11 is a chain that limits how far a door can swing, using a solid twisted chain with compression springs at one end to absorb the stop, and it mounts with the supplied wood screws. A floor or wall bumper only cushions the door where it lands and does not restrain the swing. If you want a chain-type restraint, the comparable product is the Trimco 4048 chain crash stop.

The twisted chain carries a gray vinyl cover. The vinyl is there so the chain doesn't scuff or gouge the door face or frame when it swings and falls slack, which matters on a painted or finished door.
