Nonconductive Lockout Hasps





Ideal for circuit breakers and other electrical equipment, these hasps are made of nonconductive plastic to prevent shocks. They also resist corrosion better than hasps with a metal body. Use them to lock out controls to keep machinery off while completing repairs. They have multiple holes for multiple padlocks and tags, so each person can add their own as they start the job. Until the last padlock is removed, these hasps won’t open. They help you comply with OSHA 29 CFR 1910.147, which requires electrical controls to be locked out during maintenance to prevent injuries.
Style B have a slot instead of multiple holes, so it’s easier to install multiple padlocks.
Style C have a flexible clasp that you can bend to fit around irregular shapes. They also have a prominent warning label on the body.
Style D are good for tight-clearance applications, such as on circuit breakers. They have a thin, lightweight design.
Style E are bright red and shaped like a stop sign to remind you to be cautious near locked out equipment.
Hasps that meet UL 2809-2 are made of 100% recycled materials and are sustainably sourced to meet purchasing requirements for LEED-certified facilities.

Lockout Hasps


Lock out electrical panels, switches, and other power sources to keep machinery off during repairs. These hasps have multiple holes for multiple padlocks and tags, so each person can add their own as they start the job. Until the last padlock is removed, these hasps won’t open. They help you comply with OSHA 29 CFR 1910.147 requirements for the control of hazardous energy.
Aluminum hasps resist corrosion better than steel hasps, so they won’t wear as easily. Steel hasps are stronger than aluminum and stainless steel hasps. Stainless steel hasps are both strong and corrosion resistant. While not as strong as steel hasps, they resist corrosion much better. They’re also stronger and more corrosion resistant than aluminum hasps.
Vinyl- and epoxy-coated hasps won’t scuff the surfaces they touch.
