Overview
OSO Rubber Collar Plugs are high-quality, impact-absorbent replacement inserts designed specifically for the OSO cam-locking collar line. Manufactured in Colorado from durable vulcanized rubber, these plugs provide the critical friction point between the collar and the barbell sleeve. Available in a wide variety of colors, they allow athletes to customize their gear while ensuring superior holding power and protecting the barbell’s finish during heavy drops.

Performance Benefits
Superior Grip: The vulcanized rubber is engineered to "bite" onto the barbell sleeve, preventing plate drift during high-repetition functional fitness and Olympic lifting.
Impact Absorption: Acts as a buffer between the rigid collar frame and the barbell, protecting both the equipment finish and the mechanical integrity of the collar during high-impact drops.
Customization: Easily match your collars to gym branding, team colors, or personal preference.
Installation Instructions
Step 1: Align the plug so it sits evenly atop the internal slot of the OSO collar.
Step 2: Using your thumbs, gently push the plug into the slot, alternating from top to bottom. Do not force the plug in, as this may cause it to stick unevenly.
Tip: If the plug is difficult to insert, lightly moisten the sides with water to help it slip into position.
Step 3: Once the plugs are roughly in place, perform a couple of clamping cycles on a barbell to fully seat the rubber into the machined pockets.
Maintenance and Care
Cleaning: Periodically wipe the plugs with a damp cloth to remove accumulated chalk, dust, and sweat. Clean rubber is essential for maintaining maximum friction grip.
Inspection: Check the plugs regularly for significant wear or hardening. If the collar begins to slide on the bar even when locked, it is time to replace the plugs.
Chemical Safety: Avoid using oil-based lubricants or harsh cleaners on the rubber, as these can degrade the vulcanized material and cause slipping.
