The Stanley 17‑inch FATMAX Pro‑Stack Foam Insert is a customisable foam organiser designed to sit snug inside your Pro‑Stack or TSTAK modular storage box, so you can finally sort your kit the way you want without all the rattling and loose tools flopping around.

This isn’t some flimsy sheet of foam — it’s a cushioned storage insert that you carve or configure to fit around power tools, hand tools, bits and accessories, keeping them padded and easy to grab when you’re heading out to a job.

Key Features:

• Customisable Foam Cells - lets you tailor the layout around oddly shaped tools so nothing moves when you tote your box to site.
• Pro‑Stack & TSTAK Compatibility - fits your modular storage boxes without fuss, so inserts stack with your system.
• Protective Padding - cushions tools against knocks and drops during transport.
• Compact 17‑inch Size - fits standard shallow Pro‑Stack boxes, giving you organised storage without wasting space.
• Durable Construction - holds its shape job after job — and won’t crumble into dust on you.

Applications

The foam insert is perfect for serious tradies or gear heads who need custom internal organisation in their tool storage boxes, whether it’s for power tools, cordless drills, ratchets, sockets or delicate measuring bits that you don’t want clanking around on the truck or in the van.

Why Choose This Model

Here’s the thing — a bare Pro‑Stack box is great, but without tailored cushioning and defined slots, tools slide and ding each other. This Pro‑Stack Foam Insert brings order to chaos, adds a layer of protection during transport, and makes unpacking at the job site way quicker.

Technical Specifications Explained

• Dimensions (430 x 300 x 70 mm) - gives you a full‑width insert to fit the typical 17‑inch Pro‑Stack shallow box.
• Material - dense foam that holds cut edges and resists tearing even when you’re rough with it.
• Compatibility - designed for PRO‑STACK™ and TSTAK systems so it mates with stackable toolbox units.
• Weight - lightweight enough that it won’t add bulk yet solid enough to support heavy tools.
• Pack Quantity - single insert, ready to drop into your box and customise.

Who Should Buy This

If you’re a pro or DIYer tired of digging through jumble inside your toolbox, this is the foam insert upgrade you’ve been missing — it makes sense for anyone who carries combo kits, cordless sets, sockets or impact drivers and wants organised, cushioned storage.

And if you pair it with your Pro‑Stack gear, you’ll wonder why you didn’t do it sooner — seriously, it’s one of those small tweaks that changes how your whole setup feels on site.
