The magnet is a great touch, the hold is solid, and they work exactly like they should. I get comments on them all the time at the gym. Definitely a high-quality set of collars. Review: Best Oly Lifting clamps! They never let go!! - I cannot recommend these enough!!! I have tried them all! These are the ONLY clamps I’ve used that can hold up to repeated dropping from Deadlifts, Cleans, Snatches, etc! Only complaint is be careful when in clamping them as the spring has quite a bit of tension in it and can pop you pretty good in the fingers if you’re not careful. Not a big deal, you’ll only do that once or twice before you learn :) ## Features - NO MORE SLIDING PLATES OR RATTLES – Tired of loose weight clamps ruining your sets?

Mine don't, they are the same so the push away from each other.** A: I don't think they are suppose to stick together. They are suppose to stick on metal racks or weights. If you line the magnets up so that two of the same poles face each other, the magnets will push away. This is called repulsion. Opposite poles attract each other, but similar poles repel. **Q: What's the width of this lock-jaw flex quick release aluminum barbell collar?** A: 1.25" width **Q: Are these suitable for long term use outdoors (uv/rust resistance) ?** A: They are anodized aluminum, plastic, and rubber. I think the rubber and plastic clip would have difficulty being out in the weather. If stored outside but not in the weather I think they would be fine (not direct sun for longevity). **Q: Does this work on axel (1.9 inch) bars?** A: Lock-Jaw Flex is for 50mm / 2" bars only. (Lock-Jaw PRO 2 AXLE fits all 1.9" bar diameters) ## Customer Reviews ### ⭐⭐⭐⭐⭐ go magnets *by W***S on April 21, 2026* These feel premium. The magnet is a great touch, the hold is solid, and they work exactly like they should. I get comments on them all the time at the gym. Definitely a high-quality set of collars. ### ⭐⭐⭐⭐⭐ Best Oly Lifting clamps! They never let go!! *by M***L on November 10, 2025* I cannot recommend these enough!!! I have tried them all! These are the ONLY clamps I’ve used that can hold up to repeated dropping from Deadlifts, Cleans, Snatches, etc! Only complaint is be careful when in clamping them as the spring has quite a bit of tension in it and can pop you pretty good in the fingers if you’re not careful.

They also do not slip at all, even when you have to drop your dumbell at the end of a set. These things look incredible and have a surprisingly narrow profile compared to others ive used. ## Frequently Bought Together - Lock-Jaw Flex Quick Release Aluminum Barbell Collar with Magnet (Grey) - Lock-Jaw PRO 2 Barbell Collar - Quick Release Barbell Clamp - CAP Barbell Rubber Olympic Bumper Plate | Multiple Options/Colors --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/420570464-lock-jaw-flex-barbell-collars-olympic-barbell-clamps-w-magnet](https://www.desertcart.co.th/products/420570464-lock-jaw-flex-barbell-collars-olympic-barbell-clamps-w-magnet) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-06-04*
