OSO Care

These Collars are designed to take a lot of abuse when clamped on a barbell. Aluminum will bend, therefore when they are not on a bar, avoid throwing, kicking, stepping on or any other means of abuse as this will void your warranty. These collars weigh in at 1 pound a pair, have pockets machined in the faces to protect the color of the collars and are built with stronger sidewalls.

Here are some best practices:

Open the collar until it clicks - then it will stay open to slide easily on and off
Find a good place to store them. Consider an alternative to the bucket as people tend to "drop" and "throw" them in and could possible damage them.
If the rubber gets sticky - CHALK IT UP! If it gets dirty, clean it with a wet rag!

Note from OSO Barbell: "Here at OSO, we strive to have consistency in our products each and every time we make them. However, the art of anodizing isn’t a consistent process, therefore we can’t guarantee color consistency from one batch to the next. We are working with our partners to eliminate this obstacle, but feel it important to bring it to your attention. Thanks for your understanding."
