Buying Guide

Match device to energy source

Choose a lockout designed for the specific energy control point — gate valve lockouts for valve handles, circuit-breaker lockouts for toggle breakers, and group lock boxes for multi-person lockout scenarios

Check voltage and amperage compatibility

For electrical work, pick devices rated for the system voltage (for example, products specified for 480/600V) to ensure they meet insulation and safety needs

Prefer durable materials and visibility

Look for rugged, high-visibility colors like red and materials resistant to industrial wear so devices remain identifiable and functional in harsh environments

Consider group lockout workflow

Use a group lock box when multiple workers need individual control over a single energy isolation point to maintain personal accountability and secure keys

Verify fit range and adjustability

Confirm the lockout fits the hardware you have — gate valve models list handle size ranges (e.g., 6.5–10 in or 10–13 in) and breaker lockouts note compatibility with standard toggle profiles
