How Wolf Lock™ Works on Site
Wolf Lock™ is our patented locking system. Here is what it does on your site:
Three-point lock. The door locks at three points, and the system is patented.
One hand, one motion. Unlock the door without bending or straining, which cuts manual handling risk.
Opens from inside. If the door closes by accident, the patented interior release opens it from inside. A glow-in-the-dark exit label shows where it is in low light.
Weather-resistant steel. Steel storage for your equipment and materials, built to resist the weather.
Options. Shelving or racking, access ramps and added padlock protection.
Tell us what you are storing, how often you need access and what your site looks like. We will recommend a size.
With 52,000+ containers, 40+ Customer Service Centres in Australia and 28 in New Zealand, we offer unmatched reach and a 105+ product range spanning storage, refrigerated units, dangerous goods, portable buildings, intermodal, self-storage and more.
In-House Engineering & Manufacturing
Our design, engineering and manufacturing teams deliver fully customised builds; from modified site offices and defence facilities to bespoke community and commercial pop-up solutions.
Rapid Deployment for Any Site
We deliver fully equipped container solutions that can be operational within minutes, reducing setup time on remote or fast-moving projects. Our solar-powered Site Hub units, pre-fitted with water tanks, are one example of our rapid-deployment capability.
ISO-Certified Quality & Safety
We follow ISO 9001:2015 and robust OH&S systems to ensure consistent quality, compliance, and reliable performance across every container and project.
Industries We Support
Wolf Lock™ containers work on a range of sites, including:
Construction Sites Lock-up for tools, equipment, construction materials and site supplies.
Industrial Facilities Secure storage for inventory, equipment and bulky items that need extra internal height.
Remote Depots One-hand opening for crews who need to reach stored equipment regularly.
Secure Self Storage Secure storage for business or personal use, with an interior release.
Wolf Lock is a container door system that locks at three points.
What if the door closes while I am inside?
You can open it from inside. A patented interior release opens the door if it is closed by accident, and a glow-in-the-dark exit label shows where it is in low light.
Can I open the container often on site?
Yes. The handle opens with one hand in a single motion, so crews can reach stored equipment quickly and often.
Do Wolf Lock containers have double doors?
No. They are single-entry units, so you can only get in from one end. If you need access at both ends, ask us about double door containers.
How is the container delivered?
Common methods are tilt tray, side loader and crane truck, depending on site access. When you book, tell us which way the door should face (to cabin or rear), have a level surface ready so the door operates smoothly, and flag any obstructions.
