BD‑GP4651 red long‑shackle insulated LOTO padlock, 76mm non‑conductive nylon shackle dust‑shuttered safety lock for deep‑cavity circuit‑breaker emergency lockout

Push‑pull dust‑proof shutter long‑beam dielectric padlock, OSHA‑compliant red LOTO lock for large‑gap power‑cabinet emergency lock‑out work

Red 76mm Non-Conductive Safety Padlock for Electrical LOTO

BD-GP4651

The BD-GP4651 red safety padlock features a 76mm fully non-conductive nylon shackle and is specifically designed for emergency, high-risk electrical isolation of large circuit breakers with deep-set mounting points and for multi-person lockout applications. Its vibrant red finish signals ongoing emergency power-off operations, while the extra-long shackle reaches deep into enclosures and accommodates multi-hole group lockout hasps, meeting the requirements of collaborative maintenance lockout procedures.

76mm inner-height full-dielectric nylon shackle reduces arc-flash risk; extra-long reach covers recessed breakers and multi-hole group hasps, overcoming the limits of 20mm/38mm insulated shackles
Industry-standard bright-red finish for emergency high-risk de-energization — instant visual alert for large-gap, deep-cavity and multi-person-locked assets, clearly differentiated from routine-grade short-shackle locks.
Purpose-optimized sliding shutter seals the keyway at rest, blocking conductive carbon dust and fine metal swarf common in power premises — reducing lock-core fouling for long-duration emergency isolation and repeated group lockout.
One-piece high-impact PA-nylon body, rated −20 °C to +100 °C, resistant to chemical splash and UV ageing — suited to indoor substations, large distribution workshops and semi-outdoor HV zones.
Key stays captive when unlocked, reducing the risk of abandoned open locks on jointly-locked high-risk assets during hand-overs; optional self-elastic long shackle speeds up frequent multi-person lockout cycles.
Supports multi-language luminous warning labels, laser-engraved asset IDs/safety logos, multiple lock-body styles, 8 colour options and zinc-alloy/brass cylinder upgrades for large-plant emergency and group-lockout programs.

FAQs

1What key difference separates BD‑GP4651 76 mm long‑shackle red padlock from BD‑GP4621 38 mm short‑shackle red insulated padlock?

Both are red emergency high‑risk electrical‑isolation locks. The **76 mm extended shackle delivers extra length** for recessed deep‑cavity breakers, large‑gap cabinet latches and multi‑hole group lockout hasps. Standard 38 mm shackles cannot physically reach or pass through these special lock‑points, making this long‑beam model essential for multi‑person joint‑lockout and sunken‑mount electrical equipment.

2What typical lock‑points require a 76 mm long non‑conductive shackle?

Recessed / deep‑cavity mounted circuit‑breakers, wide‑gap power‑cabinet latches, and multi‑person group lockout hasps where multiple padlocks must pass through the same hasp aperture.

3Why use dust‑proof shutter for long‑shackle emergency‑isolation padlocks?

Substations accumulate conductive carbon dust and metal particles. Long‑shackle padlocks are often left locked for extended emergency‑shutdown periods. The push‑pull shutter seals keyway at rest and prevents contaminants from jamming the lock cylinder when technicians need to restore power.

4Can I laser‑mark electrical‑asset‑IDs for large‑substation traceability?

Yes. We support laser‑engraved electrical‑asset identifiers and enterprise safety logos, paired with multi‑language luminous warning labels, ideal for auditable emergency and group‑lockout management in large‑power‑plant facilities.

5What environmental conditions can this long‑shackle emergency‑grade insulated padlock endure?

Reinforced PA‑nylon housing performs reliably from‑20 °C to +100 °C. It resists industrial chemical splashes and long‑term UV‑exposure, suited for indoor substations, large‑distribution workshops and semi‑outdoor high‑voltage‑equipment yards.
