Buy Group Lockout Boxes Online in Australia
A group lockout box lets a crew isolate one machine or system together. The keys to the isolation locks go inside the box, and each worker puts their own padlock on the box, so the keys stay locked away until the last person has taken their padlock off. This range covers portable and wall-mount boxes from Master Lock and Brady, in capacities from 7 to 55 padlocks.

Choosing a group lockout box
- Capacity: count the people who will lock on at the same time, then choose a box that holds that many padlocks with room to spare. Listed capacities run from 7 and 12 (Brady) to 30 and 55 (Master Lock). Capacity for the other boxes is not shown in the listing, so ask us.
- Portable or wall mount: portable boxes travel to the job. Wall mount boxes stay at a fixed isolation point such as a switchroom or plant area.
- Colour: the Master Lock Latch Tight boxes come in red or yellow, which makes it easy to tell boxes apart if you run more than one on site.
- Permits: the permit display case is for displaying permits and paperwork, not for holding padlocks.
Always check the data sheet. Capacity, mounting and how the box locks vary by model. Check the manufacturer's data sheet against your isolation points and your site lockout procedure before you buy.

Group lockout box questions
How does a group lockout box work?
After the energy sources are isolated and locked, the keys to those isolation locks are placed inside the box. Each worker then applies their own padlock to the box. The box can only be opened once every worker has removed their padlock, so the isolation cannot be released while anyone is still working.
How many padlocks does a group lock box hold?
It depends on the model. The Brady Wallmount box is listed at 7 or 12 padlock capacity, and the Master Lock portable boxes with a window at 30 or 55 lock capacity. For the other boxes, contact us and we will confirm capacity.
Should I choose a portable or a wall mount box?
Choose portable if the box has to move between jobs or sites. Choose wall mount if the same isolation point is locked out regularly and the box can live at that location.
Do I still need individual padlocks?
Yes. A group lockout box holds the padlocks, it does not replace them. Each worker applies their own padlock to the box. See our padlocks range, and check each listing for what is supplied.
When should I use a hasp instead of a group lockout box?
A multi-lock hasp suits a single isolation point with a small team. A group lockout box suits a larger crew, or a job with several isolation points where the keys are gathered in one place.
What is the permit display case for?
It is a Master Lock display case, 440 x 308 x 57mm, for displaying permits and isolation paperwork next to the lockout point. It is not a lock box.
