These endcaps mount with button head screws into the threaded end of your rail, covering the open channel and giving your rack a finished look while protecting the inside of the T-slot from dirt and trail debris. Specifications: Profile: Select 1530 or 1515 Material: Durable plastic Mounting: Button head cap screws into threaded extrusion ends Which profile do I need? 1530 endcap — fits 15mm × 30mm T-slot rail (includes 1 endcap + 2 button head screws) 1515 endcap — fits 15mm × 15mm T-slot rail (includes 2 endcaps + 2 plastic push-in retainer clips) Use these endcaps on any XTR bed rack, custom build, or extrusion project to give exposed rail ends a clean finish.
