Perfect and much cheaper than when bought in a kit
These are larger lockouts than the small panels that you usually have at home. 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!
