Couldn't load pickup availability
Stop wrestling 4×8 sheets solo. FlatGrab connects two GRABO vacuum lifters into one balanced rig — so plywood, MDF, and LVT lift flat, stay flat, and walk where they need to go without flexing, slipping, or eating your back.
If you've ever tried to maneuver a full sheet of ¾" plywood or a stack of LVT planks alone, you already know the problem. One person can't grip both ends. Two people slows the job down. And edge clamps mark the material.
FlatGrab fixes that. The steel spreader bar locks between two GRABO units, turning a pair of single-handed vacuum lifters into a wide-stance dual-grip rig. Lift from anywhere on the sheet, walk it across the shop, drop it where it goes. The sheet stays flat because the load is balanced over two suction points instead of dangling from one.
Designed and built by STV Racking — the same shop that makes Milwaukee Packout accessories and contractor organization gear for working pros.

FREQUENTLY ASKED QUESTIONS
Still stuck? Contact Us Directly.
What are STV Racking products made of?
Depends on the product. Our plywood components (towers, drawers, shelving) use UV Birch Plywood. Smaller organizers and inserts are 3D printed, typically in ABS, with some items made from PETG or HDPE depending on the application. Each product page lists the exact material.
What thickness of plywood is used in STV Racking products?
STV Racking builds most current products in 3/4" plywood. If you need 1/2" material for an older system or a specific reason, use the Design page or email us to start a custom order.
Will my product's color match the photos exactly?
For 3D printed items, color can vary between orders. You may receive black, red, or gray depending on what's in stock when your order is made. If color matching matters for your setup, mention it in your order notes or email us before ordering.
Are STV Racking's 3D printed products heat resistant?
Reasonably, but not indestructible. Products made from ABS offer solid heat resistance compared to PETG or PLA, but ABS can still warp or deform if left in direct sunlight, a hot vehicle interior, or near any heat source for extended periods. Heat-related damage isn't covered under warranty, so treat your organizers the way you'd treat anything else that lives in a truck bed in July.
Do your products work with Dewalt, Ridgid, or other systems besides Milwaukee?
Yes. Several of our tower and drawer products are available in Dewalt ToughSystem 2.0, Ridgid Pro Tool Storage, and Systainer configurations in addition to Milwaukee Packout. Look for the size or tower-type dropdown on the product page.
Can I mix and match brands within one STV Racking system?
Yes, and a lot of our customers do exactly that. Our gallery has real setups combining Packout, Systainers, and other brands on the same tower.
Do STV Racking products come assembled?
Plywood systems (towers, drawers, shelving) ship flat-packed and require assembly. Most can be put together in under an hour with basic tools. 3D printed organizers and inserts arrive ready to install, no assembly required.
What do I need to assemble a tower or drawer kit?
Wood glue and your choice of mechanical fasteners. Glue, brad nails, and screws are not included. Our recommended method: wood glue, then 18-gauge brad nails, then predrill with a #8 countersink bit and secure with a 1.5" #8 SPAX screw. Clamping joints while the glue sets gives you the cleanest finish.
Is there an assembly video?
Yes. You can find it on our Assembly page, and a QR code linking to it ships with plywood kits.
My tower feels wobbly. Is that normal?
Yes, until it's mounted. Towers are designed to be secured to the wall of your shop, trailer, or van. Make sure it's plumb before you screw it in, and the wobble goes away.
Can I get a custom-sized tower?
Height is easy to adjust. Width is standard across our systems. If you need something outside standard dimensions, a quick call or email gets you a custom quote.
Do the drawers come with dividers?
Depends on the product. Some drawer kits include optional dividers you can install however you like, split into equal sections or leave open. Check the specific listing for what's included with your size.
