Installation Tips
- Ensure the mating shaft or pin is clean and free of burrs.
- Align the retainer cap squarely with the shaft end.
- Press firmly by hand, or use a soft-face mallet if necessary—avoid metal-on-metal contact.
- Verify the cap is fully seated and flush to confirm proper retention.
Why Black?
The deep matte black finish isn’t just for aesthetics—it serves functional purposes. Black polymers absorb ultraviolet light, reducing degradation when components are exposed outdoors or in brightly lit spaces. The dark color also makes it easier to spot wear or damage, so you can perform preventive maintenance before small issues become big problems.
