Three black dielectric padlocks with plastic shackles and keys

Master Lock

Master Lock Dielectric Padlock Keyed Alike Black 1/4 in Shackle 3 Pack

SKU CH-WJFP-5FF5A

Three non-conductive padlocks with plastic shackles open with the same key

  • TypeDielectric
  • Non-conductive dielectric body protects against electrical hazards
  • Keyed-alike convenience lets one key open all three padlocks
  • Thermoplastic construction resists corrosion and chemical exposure
  • 1/4 in plastic shackle provides lightweight non-metallic locking
  • Includes two keys and labels for immediate identification

Lockout padlock set for electrical safety

This three-pack of Master Lock dielectric padlocks is built for lockout-tagout procedures where non-conductive materials are required. Each lock features a thermoplastic body and a plastic shackle that eliminate electrical conductivity. The keyed-alike configuration means a single key operates all three units, simplifying key management for maintenance teams.

Two keys and labels included per pack

The package supplies two standard keys that are non-removable while the shackle is open, reducing the chance of accidental unlocking. Danger-header labels are also provided so each lock can be marked with identification or warning information at the point of use. These accessories support compliance documentation without extra purchasing.

Suits 1/4 in shackle applications

The 1/4-inch diameter plastic shackle fits standard lockout hasps and valve cover holes, while the 13/16-inch horizontal and vertical clearances accommodate typical industrial hardware. The non-conductive construction is intended for electrical panel and circuit-breaker lockout; it is not designed for high-security physical protection or outdoor exposure where shackle cutting resistance is required.

Questions about this item

Will the plastic shackle on these Master Lock dielectric padlocks degrade and need replacing after outdoor exposure?

The 1/4 in. plastic shackle and thermoplastic body are non-conductive and resist corrosion, so they do not rust like metal shackles; inspect periodically for cuts or UV damage and replace only if the shackle shows visible wear.

What stops me from forcing the 13/16 in. shackle clearance open under sustained pulling force?

The 1/4 in. diameter plastic shackle and thermoplastic body will flex or snap before the lock mechanism yields, making shackle strength the first limit under sustained force.

Does the all-plastic construction stay cool and silent when the padlocks hang on a panel all day in the sun?

The thermoplastic body and plastic shackle do not conduct heat like metal, so they remain near ambient temperature and produce no noise during continuous use.
