Step 1: Slide on a belt sleeve
Slide a belt sleeve onto the belt.
Step 2: Route the belt through the clip
Route the belt down through the slot in the belt clip and then wrap the belt back under itself. The teeth from the short end of the belt should engage with the teeth on the long end.
Step 3: Secure the belt with the sleeve
Slide the belt sleeve over both ends of the belt. This may take a small bit of force and some wiggling.
Step 4: Mount the clip
Mount the clip to the end of an extrusion with a 20mm nut bar and two M5 x 10mm screws.
