Welds That Hold Up to Real Work

Welds That Hold Up to Real Work

A failed weld on a toolbox doesn't just mean lost tools — it means downtime, exposed equipment, and replacement costs you didn't plan for. The Chandler Underbody Steel Toolbox eliminates that risk with robotically welded 12 gauge carbon steel construction. Unlike mass-produced boxes where inconsistent manual welds create weak points, robotic welding delivers uniform, penetration-consistent seams across every joint. The commercial grade one piece gasket seals out moisture, dust, and road debris. This is a toolbox vetted for professionals who need their gear protected shift after shift, not a retail-grade box that gives out after one season.

Secure Access Without Fumbling

Secure Access Without Fumbling

The die cast heavy duty adjustable T-handle uses a roller cam mechanism that maintains consistent latch tension over time, even as the gasket compresses with use. A keyed lock integrates directly into the handle — no separate padlock to lose or freeze up in winter. For additional security, a dedicated padlock loop is built into the latch housing. The drop down door swings on stainless steel hinges that resist corrosion far better than standard plated hardware, which is critical on underbody mounting where road salt and moisture are constant. Dual 3/16 inch check chains prevent the door from overextending, protecting both the hinges and whatever you're reaching for.

Sixteen Configurations for Your Mounting Setup

Sixteen Configurations for Your Mounting Setup

With 16 available size combinations ranging from 18 by 12 by 14 inches up to 60 by 18 by 18 inches, the Chandler Underbody Steel Toolbox covers the most common underbody mounting widths on standard pickup trucks and flatbed trucks. The matte black powder coat finish provides a uniform, non-reflective appearance that holds up to underbody exposure better than painted alternatives. Each size shares the same 12 gauge carbon steel construction and hardware spec, so you're not compromising on build quality regardless of which dimensions fit your frame rails. Tank Vault carries the full size range so you can match your exact mounting footprint without settling for close enough.

Compatibility & Sizing Guide

Select from 16 available dimension configurations to ensure proper clearance and fitment for your specific truck setup.

  • Truck frame must accommodate one of the 16 available width options (18" to 60")
  • Mounting area depth must match selected depth option (11" to 24")
  • Minimum ground clearance required based on selected height option (12" to 36")

Built Tough for the Job Site

Keep your critical tools organized, secure, and out of the way with underbody storage that handles tough conditions.

“Mounted two of these under our service trucks six months ago. The 36 by 18 by 18 size fit our frame rails perfectly. No rust issues yet, the T-handle lock still operates smoothly, and the door chains are holding up to daily use. This is the kind of craftsmanship that justifies the investment — built tough enough that you stop worrying about the box and focus on the work.”
