Nylon Padlocks from Brady® have nonconductive fiberglass-reinforced nylon bodies and unique key cylinders that prevent electricity from traveling from the shackle to the key. Padlock features a non-conductive nylon shackle to protect against electrical hazards during lockout applications. These lightweight padlocks comply with all OSHA requirements and offer superior temperature, chemical and corrosion resistance. Non-conductive nylon padlocks are a safer alternative to metal locks for lockout applications. Keyed alike sets can be opened with the same key; sets keyed differently feature keys precision-machined to exacting standards, so that the key for one lock will not open another in the set.
