Right Bracket, Right Toolbox — Verified Before It Ships
Fabricating custom mounting brackets on-site wastes labor hours and creates alignment problems that follow your installation for years. The Chandler Underbody mounting brackets eliminate that risk with a built-to-spec fit for 18x16 or 24x22 underbody toolboxes. At Tank Vault, we apply our pre-offer spec review process to every order — including bracket hardware. Tell us your toolbox dimensions and vehicle application, and we confirm the correct bracket size before it ships. No guessing, no returns for wrong-size brackets, no fabrication delays on the job site. These brackets deliver a direct, secure mount to your vehicle frame when you drill and bolt with your own hardware.
Dual-Size Compatibility Covers Your Fleet
Operations that run multiple vehicle types often standardize on two toolbox sizes to streamline inventory and maintenance. These brackets accommodate both 18x16 and 24x22 Chandler underbody toolboxes with the same mounting system, so your shop stocks one bracket SKU instead of two. That simplifies ordering, reduces spare parts inventory, and means your crew always has the right bracket on hand regardless of which truck gets the next toolbox install. Select your size at checkout.
Straightforward Drill-and-Bolt Installation
These brackets require drilling holes and supplying your own mounting bolts for a secure attachment to the vehicle frame and toolbox. That is intentional — field-proven installations use hardware matched to your specific vehicle's frame thickness and material. No universal fastener kit that might not grip. No pre-drilled holes that miss your mounting points. You control the bolt grade, length, and thread pitch for your exact application. The Chandler Underbody mounting brackets give you the industrial-grade foundation; you finish the job with hardware you trust.
Compatibility Check
Verify your toolbox dimensions before ordering to ensure a proper fit.
- Toolbox measures 18" x 16" or 24" x 22"
- Vehicle undercarriage has sufficient available for bracket installation
- Mounting surface allows drilling for bolt-through attachment
Common Applications
Built for fleets that need reliable underbody toolbox mounting day in and day out.

Frequently Asked Questions
These brackets are designed for 18x16 and 24x22 Chandler underbody toolboxes. Vehicle fitment depends on your specific frame rail dimensions and available mounting points. Contact Tank Vault before ordering with your truck make, model, year, and toolbox size, and we will confirm compatibility through our free pre-offer spec review process. We verify the right bracket for your application before it ships.
No. These brackets require you to supply your own mounting bolts. That is by design — proven installations use hardware matched to your vehicle's frame thickness and material. You select the bolt grade, length, and thread pitch for your exact application rather than relying on a generic fastener kit that may not grip properly.
Lead times vary based on current inventory. These brackets ship via LTL freight nationwide at no charge to your location. If you have a specific job-site deadline, contact us before placing your order and we will confirm current stock levels and expected delivery windows. Tank Vault coordinates freight directly to your site, yard, or shop.
Tank Vault offers a 30-day return policy for uninstalled items in original packaging. That is why we encourage contacting us before you order — our pre-offer spec review verifies the correct bracket size for your toolbox and vehicle. If we spec it and it still does not fit, we resolve it immediately.
These brackets are designed for Chandler 18x16 and 24x22 underbody toolboxes. Compatibility with other toolbox brands depends on mounting hole patterns, flange dimensions, and overall toolbox depth. Contact us with your toolbox brand, model, and exact measurements, and we will assess fitment before you order. Do not assume cross-brand compatibility without verification from Tank Vault.
Specific gauge thickness is not listed in the current product specifications. Contact Tank Vault directly and we will request the material specification from the manufacturer. We do not publish unverified numbers on our product pages — if we cannot confirm the steel gauge from the source, we will tell you that directly rather than guess.
