NewBEP 2PCS Olympic Adapter Sleeve 7.8" with Olympic Barbell Clamps 2", Converts 1" Standard Weight Plate Posts to 2" Olympic Weight Plate Posts, Removable end Cap

Does exactly what I wanted - converted a standard 1" (25mm) diameter triceps bar into an Olympic triceps bar so I could use Olympic weights with it, without having to buy an Olympic EZ bar. The quick release collars lock everything down well.

To tighten the adapter tight enough to hold the bar it disfigures the shape making it problematic getting plates on and off

The material is solid and it fit my curl bar perfectly. The clamps are really tight once clamped down. I was worried they would be cheap. I have a set of clamps on my dumbells that are dangerous and slip off so I wondered how these would do. This is the only item I found for curl bars that have an approx 8" area for the plates and also comes with the clamps. Highly recommend. Now I can use my olympic weights. Get em.

Olympic Adapter Sleeve is an excellent product for those who want to expand their weightlifting options. The sleeves easily convert standard 1" weight plate posts to 2" Olympic weight plate posts, allowing you to use Olympic-sized plates with a standard barbell. The product also comes with two durable barbell clamps that keep the plates securely in place during workouts. The removable end cap is a great feature that makes it easy to slide the adapter on and off your barbell. The only downside is that the clamps are made of plastic, which may not be as sturdy as metal clamps. Overall, the 2PCS Olympic Adapter Sleeve is a great value for anyone who wants to increase their lifting potential, and we rate it 4 out of 5 stars.

Sleeves worked great for my application (adapting weight posts on Fitness Reality lat pull assembly to 2" diameter). Good fit and finish. Clamps are a bonus, but I'm not expecting them to last based on past experience with similar clamps (typically break within a year or two even with light to moderate home use).

My existing olympic sleeves a too long.

Was trying to keep some 1 inch bars we already had so we bought this product. It didn’t work. The sleeve itself you have to tighten the nut so far it tries to pull through. Once you get the sleeve on the clamps just won’t tighten enough to keep the plates on. It’s dangerous to use this product with confidence in our home. Really had hoped for better.
