These sleeves are a super simple solution for using your existing olypic plates on a 1" bar.Easy installation with the included allen keys and pop off end caps make setup a breeze. ### ⭐⭐⭐⭐ 4.0 out of 5 stars It works. *by S***R on Reviewed in the United States on May 21, 2024* Purchased this to allow me to use Olympic plates on my leg curl attachment which does not hold Olympic plates. Unfortunately it's just 2 inches shy of the length of the plate holder on the curl attachment and the end popped off (which it is designed to do). There is no issue with the adapter, I only wish it were longer. It works as advertised. --- ## 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.sn/products/405742252-nylon-olympic-adapter-sleeve-8-convert-1-bars-or-posts](https://www.desertcart.sn/products/405742252-nylon-olympic-adapter-sleeve-8-convert-1-bars-or-posts) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-05-10*
