RATDCHK12 Truck Cab & Trailer Kit: The Battery-Powered Lockbolt Tool Built for Owner-Operators and Repair Shops | Reliable Air Tools

 

If you repair truck cabs and trailer bodies for a living, you already know the frustration of owning two separate rivet tools one for the small 1/4" fasteners on cab panels, and a heavier pneumatic unit for the 3/8" lockbolts used on trailer skins. Hauling around two tools, two hose lines, and two sets of noses eats into your bay time and your bottom line.

Reliable Air Tools built the RATDCHK12 Truck Cab/Trailer Kit to solve exactly that problem. It's a single, battery-powered lockbolt tool that installs everything from 3/16" cab body fasteners to full 3/8" Magna-Grip® lockbolts used in trailer repair no compressor, no second tool, no wasted motion.

What the RATDCHK12 Kit Actually Does

The RATDCHK12 is a cordless lockbolt installation tool rated for up to 3/8" Magna-Grip® fasteners, with a 9,500 lb. (42 kN) pull capacity and a 0.575" stroke. It runs on an 18-volt lithium-ion battery, weighs under 5 lbs, and is directly compatible with industry-standard tools including the Huck 225, 226, 245, 246, and 256, as well as the Gage Bilt 756 so your existing knowledge of those platforms transfers instantly.

Because it uses the same 1‑1/16" diameter nose housing found on trailer repair tools, and accepts 1/4" noses through the included RAT3424 reducing adapter, this kit genuinely replaces two categories of equipment. If your shop currently stocks a dedicated 1/4" capacity cab repair tool alongside a separate 3/8" capacity trailer tool, the RATDCHK12 lets you consolidate that investment into a single kit.

Why Battery Power Beats Pneumatic for Cab and Trailer Work

Traditional 3/8" capacity lockbolt guns are pneumatic, which means dragging an air hose across a trailer roof, into a sleeper cab, or under a chassis every time you need to set a fastener. At under 5 lbs, the RATDCHK12 is comparable in weight to smaller pneumatic tools like the Huck 2025 or Gage Bilt 722, so technicians can run it hands-on for a full shift without the fatigue that heavier pneumatic riveters cause and without needing shop air routed to the repair bay at all. For mobile repair units and owner-operators working roadside or at a customer's lot, that cordless freedom is the difference between finishing a job and waiting on a compressor.

What's Included in the Kit

The RATDCHK12 ships as a complete working kit, not just a bare tool:

• 3/16" and 1/4" Magna-Grip® noses for installing cab body panels
• 3/16" C6® nose for chrome grill bolt installation
• 3/16"–1/4" Magna-Lok® blind fastener nose with reducing adapter for sleeper conversions
• 5/16" and 3/8" Magna-Grip® noses for trailer panel installation

That range covers the fastener sizes most repair shops touch on a weekly basis, in one case, with one battery platform. (Note: the Makita battery and charger are sold separately, so confirm compatibility with your existing Makita 18V lineup before ordering, or add a battery kit from our accessories collection.

Built for Owner-Operators and Small Repair Shops

Reliable Air Tools designed the RATDCHK12 specifically with independent technicians in mind not just large fleet maintenance operations with unlimited air infrastructure. If you run a mobile trailer repair service, a small collision shop, or you're an owner-operator handling your own cab and body work, this tool is priced and configured to get you doing 3/8" lockbolt work without buying an industrial-grade pneumatic system you'll only use occasionally.

That matters for compliance, too. Trailer bodies and coupling components are safety-critical items under federal inspection rules  the FMCSA's periodic inspection requirements under 49 CFR § 396.17 require every commercial trailer over 10,001 lbs GVWR to pass a full inspection at least once every 12 months, with frame and body condition among the items reviewed. Repairs made with proper Magna-Grip® lockbolts, rather than improvised fasteners, help ensure that bodywork holds up to that scrutiny. Shops that follow Technology & Maintenance Council (TMC) recommended practices for fleet maintenance will find the RATDCHK12's fastener range lines up with the hardware most commonly specified for cab and trailer body repair.

Why Buy from Reliable Air Tools

Every tool in the Reliable Air Tools catalog, including the RATDCHK12, is backed by a straightforward 30-day return policy and secure checkout.

Frequently Asked Questions

Does the RATDCHK12 come with a battery and charger? No, the Makita 18V battery and charger are sold separately, so you can use batteries you may already own or select the exact capacity you need.

Can this tool install both 1/4" and 3/8" fasteners? Yes. With the included RAT3424 reducing adapter, the RATDCHK12 accepts the smaller 1/4" noses typically used for cab repairs in addition to its native 3/8" capacity.

Is the RATDCHK12 compatible with my existing Huck or Gage Bilt noses? The tool uses the same 1‑1/16" diameter nose housing as the Huck 225, 226, 245, 246, 256, and Gage Bilt 756, so most noses built for those platforms will fit.
