Compact lockout devices clamp directly onto the breaker switch to prevent accidental reactivation. The stainless steel thumb screw allows quick, tool-free adjustment, while the clamping handle locks tightly for superior grip. Built from powder-coated steel and reinforced polymer, these rugged lockouts are ideal for harsh industrial environments. Their narrow profile allows for side-by-side use on adjacent breakers, and each unit accepts standard safety padlocks and lockout hasps.
