Covers

Wear Strip

Dust Cover

Antislip Cover

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

Dust covers conceal wires and keep dust out of the T-slot. Cut covers to size with scissors and press them into a T-slot. Flip the black dust covers over and they have a groove for holding a panel inside the T-slot.

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