Site Security Boxes

If you leave tools on a site or in a van overnight, a site security box is the simplest way to keep them where you left them. Our ToolSafe site security boxes are heavy-duty steel storage boxes built to resist theft, forced entry and the weather, in six sizes to suit anything from a hand-tool kit to long levels and pipes. Every box is made from 1.5mm welded steel with an 8-lever safe lock and gas-strut lid, and can be fitted with castors or fork pockets so it moves with the job.

Why a proper site security box is worth it

Tool theft from sites and vans is one of the most common and most expensive setbacks a trade can face. It is not only the cost of replacing the tools, it is the lost days, the missed deadlines and the hit to your insurance. A cheap storage bin with a padlock hasp does little to stop a determined thief, because the weak point is never the padlock, it is the box around it.

A ToolSafe site security box is built the other way round. The 1.5mm steel body is fully welded, so there are no bolted panels to prise apart, and the hinge is fixed on the inside, which means the lid cannot be unpinned from the outside. The 8-lever safe lock is a genuine upgrade on the padlock-and-hasp boxes it sits next to on price. The result is storage that actually earns the word secure, rather than just implying it.

What our site security boxes offer

  • 1.5mm thick mild steel body, fully welded for strength with no weak bolted joints
  • High-security 8-lever safe lock, supplied with keys
  • Internally fixed hinge that stops the lid being removed from the outside
  • Gas struts that lift the heavy lid smoothly and hold it open safely
  • Six sizes, from a compact hand-tool box to a long unit for levels and pipes
  • Optional castors for manual mobility, or fork pockets for lifting by forklift
  • Durable powder-coated graphite grey finish for indoor, outdoor and in-transit use

Built to resist theft and forced entry

Security is the whole point of the box, so it is worth being clear about what does the work. The fully welded 1.5mm steel carcass has no removable panels, which takes away the quickest route in. The internally fixed hinge removes the second, because a lid that cannot be unpinned cannot simply be lifted off. The 8-lever safe lock then protects the opening itself, offering far more resistance to picking and forcing than the padlocks fitted to budget site boxes.

Together these three features, welded body, fixed hinge and safe lock, are what separate a security box from a storage box. They are also why site security boxes are widely accepted for storing valuable power tools, test equipment and small plant on unattended sites.

Site security box sizes

There are six sizes in the range, so you can match the box to what you actually carry rather than paying for space you will not use. As a rough guide:

Size (H x W x D) Typically Suits
400 x 850 x 500mm Smaller hand-tool kits and one or two-person teams.
500 x 900 x 500mm A general tool kit and a common choice for van storage.
500 x 1200 x 500mm Larger tool sets and longer power tools.
650 x 1200 x 650mm Bulkier mixed equipment and heavier kit.
1200 x 1200 x 600mm Tall storage with an internal shelf for improved organisation.
500 x 1800 x 500mm Long items such as levels, pipes and strimmers.

Castors or fork pockets: making it mobile

A site security box does not have to stay in one place. Add castors and one person can wheel the box across a flat site or workshop, which suits fit-out, maintenance and tool-hire work where the kit follows the job. Add fork pockets instead and the box can be lifted and repositioned by forklift, which is the better option for heavier loads, for loading onto a lorry, or for moving a full box between floors and compounds.

Both options can be specified on the sizes that support them, and a standard floor-standing box remains the simplest choice where the box stays put. If you are not sure which suits your site, the team can talk it through.

Ordering your site security box

Choose your size: pick from the six sizes above based on the tools you need to store and where the box will live.

Site security boxes for every trade

Site security boxes suit any trade that leaves tools and equipment unattended. Construction and groundworks teams use them to secure power tools and small plant on site overnight. Electricians, plumbers and fit-out crews use the smaller sizes for van storage. Tool and plant hire firms use them to move and protect kit between jobs, and facilities and maintenance teams keep them on site as a permanent, lockable store. Wherever expensive tools sit unwatched, a security box pays for itself the first time it stops a theft.

Site security box FAQs


What is a site security box?

A site security box is a heavy-duty steel storage box designed to secure tools and equipment left on a site or in a van. It resists theft and forced entry through welded construction, a fixed internal hinge and a high-security lock, which sets it apart from a standard storage bin.

How secure are site security boxes?

Very, when they are built properly. Our ToolSafe boxes use a 1.5mm fully welded steel body, an internally fixed hinge that cannot be unpinned from the outside, and an 8-lever safe lock, which together resist the common methods of forced entry far better than a padlocked bin.

What size site security box do I need?

Match the size to the tools you store and where the box will sit. A 400 x 850 x 500mm box suits a hand-tool kit, the mid sizes suit a general kit or van, and the 1800mm-wide unit takes long items like levels and pipes. The size guide above gives a rough steer for each.

Can a site security box be moved by forklift?

Yes, if you specify fork pockets. These let a forklift lift and reposition the box, which suits heavier loads and moving a full box between compounds or onto a lorry. For manual movement on flat ground, choose castors instead.

Are site security boxes weatherproof?

They are built for outdoor and in-transit use, with a durable powder-coated finish over a steel body. They are highly weather resistant rather than fully waterproof, so for long-term outdoor storage it is worth keeping the box on a pallet or hardstanding and out of standing water.

What is the difference between castors and fork pockets?

Castors let one person wheel the box across a flat surface by hand, which suits lighter, frequent moves. Fork pockets let a forklift lift the box, which suits heavier loads and longer moves. A standard box has neither and simply stays in place.

Are these site security boxes British made?

Yes. The ToolSafe range is manufactured in the UK from British steel, which is one reason the build quality is a step up from imported budget boxes.

What guarantee comes with a site security box?

The range carries a manufacturer’s guarantee. [Note to Lyd: confirm the exact guarantee length for ToolSafe, as sources quote up to 10 and up to 15 years, and we should state the correct figure.]
