Categories : tools
SKU : WOR-TOO-134
The DEWALT DWST88801 TSTAK Foam Insert is the simple way to keep valuable tools and equipment safe inside your TSTAK storage system. Its removable foam blocks let you create a custom layout that matches your specific gear. Unlike generic trays, this insert is constructed from a strong, rigid but lightweight material that cushions tools and prevents them from shifting during transport.
This foam insert is an auxiliary accessory for the successful TSTAK line, designed to fit inside the deep organizers DWST17808, DWST17807, and DWST17805. You can pluck or pull out individual blocks to shape the foam to whatever power tools, batteries, or hand tools you need to store. That makes it ideal for keeping a delicate measurement tool, a new power drill, or a set of bits in a snug, secure place.
The rigid foam absorbs vibration and impact, reducing the risk of scratches, dents, or damage when the case is carried or dropped. Because the insert is lightweight, it doesn't add noticeable weight to your TSTAK stack. And it's fully removable, so you can swap configurations between different jobs in seconds.
Designed specifically for the TSTAK system, this insert gives you a professional, interior look and makes every tool easy to identify at a glance. Whether you're building a mobile tool set or just keeping a spare battery protected, the DWST88801 brings order to your storage.

The TSTAK system lets you stack and organize boxes from small parts bins to deep tool boxes. Adding a foam insert converts a deep organizer into a protective enclave for your most important tools. Spend a few minutes arranging the blocks once, and every tool will have a home.
Many foam systems require plucking or cutting. This insert's removable blocks pop out easily, so you can form a custom pocket pattern with no messy knife work. For unusual shapes, snip the blocks to fine-tune the fit.
If you've invested in a quality hammer drill or a precision laser level, keeping it safe in transit is a no-brainer. The foam insert absorbs jarring and keeps tools from knocking together, which extends the life of your equipment.
It fits the DWST17808, DWST17807, and DWST17805 TSTAK deep organizers.
The foam has removable blocks to customize; you can also cut it with a sharp knife for a precise fit if needed.
Yes, it is rigid enough to hold its shape and protect tools, yet lightweight for portability.
Typical uses include power tools, batteries, chargers, drill bits, and hand tools up to the case depth.












Fits perfectly.
Great foam insert. It keeps my tools organized. The blocks are easy to remove.
I bought this to organize my drills in a TSTAK case. The foam is dense and holds tools securely. The removable blocks allow customization. It took a while to pluck out the pieces, but it's worth it. The fit is perfect in the case. It protects my tools from banging around. I'm very satisfied.
Great organizer.
Good quality foam. It's thick and durable. I was able to customize it easily.
I'm a mechanic and I keep my sockets in a TSTAK case. This foam insert is perfect. The blocks are perforated and snap out cleanly. The foam doesn't crumble. It keeps everything in its place. I bought another for my wrenches. Highly recommended.
Works well.
This foam insert is exactly what I needed. It's well made. The customization is easy.
I use this for my router bits. The foam is sturdy and holds them safely. The pre-cut blocks come out with a little push. It fits my TSTAK case perfectly. The color is nice. It's a bit expensive for foam, but it's high quality. Overall, a good investment.
Good quality.
The foam arrived with a torn block. Had to glue it together. Not happy.
I've been using this for a few months. It holds my impact sockets nicely. The foam is resilient and hasn't torn. It keeps the tools from rattling. The custom cutouts are just right. It's a great addition to my TSTAK system. I'd buy it again.
