Grub Screw Mount
Its internal grub screw clamps tightly around breaker toggles to create an unshakeable bond, preventing the device from slipping or loosening during operation. Installation takes mere seconds—simply position it, tighten the screw with a screwdriver, and you’re set. This reliable anchoring method means you can trust it to stay put, even in environments prone to vibration or knocks.

Padlock-Ready Design
An integrated padlock hole accepts an 8 mm-shackle lock, allowing you to choose your preferred padlock for maximum access control. This feature ensures that once the breaker is secured, only the right person with the right key can restore power. It’s a simple but powerful way to enforce lockout/tagout procedures across any site.
By combining the clamp and lockhole into a single unit, it reduces the chance of misplaced parts and speeds up the entire process. Teams can move from one lockout to the next without stopping to hunt for separate components. The result is a streamlined workflow and tighter security for every circuit.


Reinforced Plastic
Its reinforced plastic construction ensures long-lasting reliability under heavy use, resisting cracking and deformation even in the toughest industrial environments. This durable material also stands up to chemical exposure and temperature fluctuations, so it won’t weaken or warp over time. You get consistent performance maintenance after maintenance, without worrying about breakdowns or replacements.
By choosing a single-piece polymer design, the lockout equipment avoids seams or joints that could become weak points. That solidity translates into fewer service calls and less downtime, keeping your team focused on the task at hand. It’s safety gear you can rely on day in, day out.
Tool-Assisted Locking
Its lockout device fits and tightens effortlessly using a standard flat-blade screwdriver, enabling one-person installation in seconds. This straightforward method removes the need for specialised tools or training, so anyone on your team can apply it correctly first time. Faster lockout procedures mean less disruption to your workflow and more time spent on productive tasks.
Once in place, the snug fit prevents accidental loosening or slippage, even when panels experience vibration. You’ll spend less time checking and re-checking locks, knowing the device will stay put until you choose to remove it. That reliability keeps maintenance schedules on track and safety uncompromised.


Wide Amp Range
Its versatile design accommodates fuse holders and circuit breakers rated from 20 A up to 400 A, covering the vast majority of workplace electrical loads. You won’t need separate lockout devices for different circuits, simplifying stock management and procurement. One solution handles everything from small office boards to heavy-duty industrial panels.
That broad current range also means faster deployment when schedules are tight, since the right lockout equipment is always at hand. Eliminating compatibility concerns lets your team move seamlessly between tasks without hunting for specialised gear. The result is fewer errors and a smoother maintenance process.
Compact Footprint
Designed with a slim profile that measures just 35 × 59 × 15 mm, it slots neatly alongside adjacent devices on even the busiest distribution boards. This minimalist approach maximises available panel real estate, allowing room for labels, tags or additional protective equipment. Panels stay organised and accessible without compromising on safety.
The compact dimensions also mean easier handling in cramped switchrooms and control cabinets, reducing installation strain in tight spaces. Quick placement and removal become second nature, helping your team maintain peak efficiency. Small size, big impact.
