Still works perfectly. Purchased this for work and did not want to spend ridiculous amounts of cash for a Lock/out Tag/out kit. So purchased the items seperately and it was much cheaper and only purchased what I needed. No Waste! ### ⭐⭐⭐⭐⭐ Excelente *by on Reviewed in the United States May 12, 2026* Excelente ### ⭐⭐⭐⭐⭐ Is 30-seconds of work worth it to save your life? *by on Reviewed in the United States December 1, 2024* I was very pleased this was adjustable enough to fit this breaker handle. Was a 480Vac 3ph panel board. I found it fits a variety of BKRs from ABB, Siemens, Eaton, Sqr-D, LS-Electric & others. Don’t panic if the angle of the grippers doesn’t perfectly align with the angle pitch of your breaker handle, just tighten it down, lock it, & you’re good to go. I trust it on the job. Great value, easy to use, it’s worth 30-seconds to keep me alive. ## Frequently Bought Together - Master Lock 491B Lockout Tagout Circuit Breaker Lockout, Tall and Wide Toggles, Red - Master Lock Red Lockout Tagout Safety Padlock with Key, Metal Shackle and Non-Conductive Lock Body for Electrical Applications, 410RED - Master Lock Safety Series 1' Jaw Steel Lockout Hasp --- ## 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.sc/products/7392959-master-lock-491b-lockout-tagout-circuit-breaker-tall-and-wide](https://www.desertcart.sc/products/7392959-master-lock-491b-lockout-tagout-circuit-breaker-tall-and-wide) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-09-23*
