Covers

Wear Strip

Dust Cover

Antislip Cover

Wear strip covers slide into a T-slot to provide a slippery, abrasion-resistant surface.

Dust covers press into a T-slot to conceal wires and keep dust out. Plastic dust covers can be cut to size with scissors. Flip the black dust covers over, and they have a groove for holding a panel inside the T-slot. Aluminum dust covers are more durable than plastic ones. They give aluminum rails a finished appearance.

Antislip covers add traction to a rail. Push them into the T-slot.
