How it connects
The stop collar slides axially onto the cylindrical rail to the desired travel limit and clamps rigidly via one or more hex socket set screws, with rubber bumper rings cushioning roller impact.
Male and female halves
Female cylindrical bore on the door stop slides over the male solid or tubular round rail.

How to recognise it
A metal sleeve or cylindrical body (often stainless steel) with an axial circular bore sized to slip over a round tube, a recessed set screw on the bottom/back, and a rubber O-ring or bumper on the contact face.
Often confused with
| Confused with | How to tell them apart |
|---|---|
| Flat track barn door stop | Flat track stops clamp onto a rectangular bar (flat rail) rather than having a cylindrical sleeve mating with a round tube/rod. |
| Round rail wall bracket | Wall brackets mount perpendicular to the wall to support the rail, whereas stops are positioned along the rail specifically to arrest roller travel. |
