Knowing how to choose a site security box comes down to three decisions: the size you need, how you will move it, and how well it holds up to a determined thief. Get those right and you have a steel box that protects thousands of pounds of tools for years, whether it lives in a compound, a cabin or the back of a van. This guide walks through each decision using the ToolSafe range, which runs to six sizes and three mounting options.
A site security box is a heavy steel chest built to lock tools and equipment away on a working site. It is a step up from a plastic site box or a tool bag: the ToolSafe version is welded from 1.5mm mild steel, finished in powder-coated dark grey, and fitted with a high-security 8-lever safe lock and an internally fixed hinge so there is no exposed pin to knock out. Gas struts hold the lid open while you load, and the box carries a Reaction to Fire Classification to EN 13501-1. It is designed to be bolted down, lifted by forklift or wheeled about, depending on how you specify it.
Size is the decision most people get wrong, usually by going too small. The honest rule is to buy for the kit you want to lock away plus a bit of room to work, not for the kit you can just about cram in. The ToolSafe range gives you six sizes, listed here shortest to tallest, with a plain steer on each.
| Size (H x W x D) | Best For | Choose This If |
|---|---|---|
| 400 x 850 x 500mm | Hand tools and small power tools | You want a compact, low box for a van or a one or two-person job |
| 500 x 900 x 500mm | A small crew’s daily kit | You need a bit more height to stack drills, grinders and consumables |
| 500 x 1200 x 500mm | A mixed load of power and hand tools | You want the popular all-rounder with a real working footprint |
| 500 x 1800 x 500mm | Longer items and awkward kit | You store levels, cable, trunking or longer power tools |
| 650 x 1200 x 650mm | Bulkier tools and mid-size plant | You need depth as well as width for heavier equipment |
| 1200 x 1200 x 650mm | A whole team or compound | You want one large, full-height cabinet for shared tools and plant |
If you are between two sizes, size up. A box that is slightly too big costs a little more once and solves the problem; a box that is too small gets left open, or tools get left out, which defeats the point.
Every ToolSafe size comes three ways, and the right one depends on whether the box stays put or travels. This is worth deciding before you order, because it changes how the box is built.
The standard option. Bolt it to a solid floor and it is not going anywhere without serious effort and serious noise, which is exactly what you want for an overnight store. Choose static for a fixed compound or a cabin where the box lives in one place.
See our ToolSafe® Site Security BoxesChannels underneath let a forklift lift and move the box while it is fully loaded. Choose fork pockets for larger sites where the store gets repositioned, or where the box needs craning or forking into place at the start of a job.
See our ToolSafe® Site Security Boxes with Fork PocketsWheels turn the box into a mobile store you can push between bays or into a lock-up at night. Choose castors where tools follow the work around the site during the day. Bear in mind a box on castors is easier to move for everyone, so it belongs somewhere it can be locked away or chained overnight.
See our Mobile ToolSafe® Site Security BoxesNot all steel boxes are equal, and the security is in the detail rather than the badge. Four things do the real work on a ToolSafe box.
Gas struts and the fire classification are not security features, but they matter for daily use and site compliance, so they are worth having as standard.
Price matters, but frame it against what the box protects. A single site security box guards tool kits that often run well into four figures, and a break-in costs you the tools, the downtime and the insurance excess all at once. The sensible approach is to buy the right size in a proper 8-lever welded box, rather than saving a little on a thin-gauge box that a thief opens in a minute. WI Products lists the full ToolSafe range and aims to be keenly priced across every size.
The 500 x 1200 x 500mm box is the usual first choice. It has enough width for a mixed load of power and hand tools without being so large that it is hard to place or lift.
ToolSafe® boxes are welded from 1.5mm steel and powder-coated to stand up to an outdoor site, so they cope well with the weather in normal use. If you need a formal weather or ingress rating for a specific setting, check the exact specification before you buy.
Yes, if you order it with fork pockets. The channels underneath let a forklift lift and reposition the box while it is fully loaded, which is useful on larger sites.
