JCB Site System Review: Modular Tool Storage Tested Against the Price Tag

By Mark Moore, Power Tools Editor · Updated 18 August 2026 · 12 min read

JCB has quietly built out a full modular storage range - the Site System - to sit alongside its Pro 18V tools, which we've reviewed extensively on this site. Where Milwaukee and DeWalt sell storage as an accessory to their cordless platforms, JCB is selling it as a standalone case for the price-conscious trade buyer, whether or not you own a single JCB tool. We've gone through every module in the range to see whether the price gap over the two market leaders is a genuine saving or a false economy - and further down, we've looked at Keter, Ridgid, Magnusson and AEG's rival systems, and the question everyone actually asks: do any of these boxes interlock with each other?

What's in the Site System range

Unlike a single "starter kit", JCB sells the Site System as nine separate modules that stack and latch together, so you can build a set that matches your van rather than buying a fixed bundle. Two pre-built kits cover most buyers:

The headline feature: wall-mounting, out of the box

Every JCB Tools storage module in the range is IP65-rated against dust and water and can be mounted directly to a wall or van racking, no adapter plate required. That's the one genuine point of difference against Milwaukee PACKOUT and DeWalt TOUGHSYSTEM 2.0, both of which need an additional mounting bracket bought separately to do the same job. If you split your time between mobile jobs and a fixed workshop bench, that's a real saving rather than a marketing line - JCB's boxes work as van storage on Monday and shelf storage on Tuesday without buying anything extra.

Mobility and build

The rolling base (JCB-SITESYS-C) and the 3-drawer rolling box (JCB-SITESYS-C3D) both run on 9-inch wheels, which is the same wheel size Milwaukee and DeWalt fit to their trolleys and is large enough to cross rutted site ground rather than just a smooth workshop floor. Everything is moulded from polypropylene rather than the glass-reinforced nylon some premium ranges use, which keeps the price down but means the boxes flex slightly more under a fully loaded stack than a PACKOUT box does - noticeable if you're stacking three or four full boxes on the trolley over rough ground, not an issue for van storage or bench use.

Load ratings: the number that needs a caveat

This is worth being upfront about. JCB's own product listing for the base cart (JCB-SITESYS-C) states a 72kg load rating; some of JCB's own marketing copy elsewhere quotes the assembled 3-piece cart at up to 113kg - the same figure Milwaukee and DeWalt quote for their trolleys. We can't reconcile the two JCB figures from published information, so we've used the lower, directly-sourced 72kg figure throughout this review and comparison table below. If the load rating is critical to your decision - stacking multiple full boxes of steel fixings, for example - check JCB's current spec sheet for the exact configuration you're buying before relying on either number.

JCB Site System vs Milwaukee PACKOUT vs DeWalt TOUGHSYSTEM 2.0

One thing worth stating plainly: Milwaukee PACKOUT and DeWalt TOUGHSYSTEM use different latch geometry to everything else in this article, and neither is compatible with JCB, Keter, Ridgid, Magnusson or AEG's systems. JCB's own storage, though, has more interesting cross-brand history than that headline suggests - see the dedicated section below.

More budget and own-brand rivals: Keter, Ridgid, Magnusson and AEG

JCB isn't the only challenger undercutting Milwaukee and DeWalt. Four more names come up constantly in modular storage searches - one of them, Keter, turns out to matter more than most buyers realise.

Keter (Stack 'N Roll and ROC Pro Gear)

Keter sells two tiers: the entry-level Stack 'N Roll range, from around £35 for a standalone toolbox up to roughly £115 for a 3-piece cart system, and the heavier-duty ROC Pro Gear line aimed more squarely at trade use, running from about £30 for a single crate up to £225 for a full system - ROC Pro Gear also adds a folding work table and a sawhorse that clip into the same stack, which nothing else in this article offers. Keter markets some of its own boxes with a "cross-system tray", explicitly designed so Stack 'N Roll and ROC Pro Gear pieces mix with each other. That's Keter's own intentional, supported compatibility - not to be confused with the JCB question below.

Ridgid Pro Gear System (Gen 2.0)

Ridgid's modular range is primarily a US product sold through Home Depot, built around a stackable 22-inch box with heavy-duty latches and handles, plus a detachable mobile gear cart. It doesn't have an official UK retail presence, so treat it as a reference point rather than a buying option here - it's relevant mainly because of how closely it resembles JCB's Site System, discussed below.

Magnusson (B&Q / Trade Point)

B&Q's own-brand Magnusson range actually covers two different systems. Magnusson Site System - yes, the same name JCB uses - is a toolbox, organiser and wheeled cart line with metal stacking locks and a telescopic-handle trolley. Magnusson Stakkur is a separate, apparently newer modular range with a drawer-chest configuration and its own tool case sets. B&Q doesn't publish load ratings or any cross-brand compatibility claims for either line, and we haven't found confirmation of who manufactures them.

AEG QuickStack

AEG's system - the HD Deep Roller Box, HD Mid Toolbox and HD Technician Case - uses its own "sliding interlocking system" and, at the time of writing, is sold only as part of AEG power tool combo kits rather than as standalone boxes. It's the most closed of the systems here: no standalone purchase route in the UK, and no compatibility claims with anything outside AEG's own range.

Cross-compatibility: what actually interlocks with what

Officially: nothing here is designed or warrantied to mix across brands. Every manufacturer sells its modular range as a closed system, and none of JCB, Keter, Ridgid, Magnusson or AEG publish a compatibility statement covering another brand's boxes.

Unofficially, it's more interesting. JCB's Site System, Ridgid's Pro Gear (Gen 2.0) and Screwfix's own-brand Erbauer Connecx range are frequently pointed to online - in forum threads and reviewer videos - as sharing very similar tooling: near-identical latch geometry, box dimensions and stacking rails, consistent with all three being manufactured on common moulds by Keter ( it could possibly come from the same factory in Israel) , who also sells storage under its own name. Some owners report that boxes from these ranges will physically stack and latch onto each other. We have been able to confirm this and tested this, however it isn't documented in any official spec sheet - so this remains 'unofficial'.

Where compatibility is confirmed: Keter explicitly designs its Stack 'N Roll and ROC Pro Gear ranges to cross-connect with each other via a shared tray system - that's official, intentional and supported by Keter itself.

Magnusson's Site System shares JCB's naming and a broadly similar spec sheet, which raises the same "same factory" question, but we've found nothing from B&Q, Magnusson or JCB confirming or denying it. AEG QuickStack and the Milwaukee/DeWalt systems above use distinctly different latch mechanisms and aren't rumoured to interlock with anything outside their own ranges.

Practical advice: if you're tempted to mix brands to save money, buy one box from each range first and test the physical fit yourself before committing to a full stack. Don't load a mixed stack with anything heavy enough to matter if a latch fails, and don't expect either manufacturer to honour a warranty claim on a box that's been paired with a rival's system.
