Convert your Harbor Freight Series 3 27" or 42" Toolbox into a proper dual-tank welding cart. This kit bolts on using the cart's existing holes — no welding required — and includes a top mount with ratchet straps to secure two bottles, plus built-in TIG rod holder mounts.
No welding required
Bolts directly onto your cart's existing holes for a straightforward install.
Powder coated: Every item in this kit except the welding top is powder coated to match your cart, which is why prices are higher than our standard kits.
Powder coating lead time: Powder coated kits take a little longer to ship than the raw steel version. The powder coating is done by a third-party supplier.
Features
Ratchet-strap top mount — securely holds two tanks up to 9-1/4" (T) size
3 TIG rod holder ports — sized 2-1/8" to fit standard 2" rod holders
No-weld install — uses the cart's existing mounting holes
Caster relocation hardware included — 3/8" carriage bolts and nuts for the new bottom deck
Harbor Freight Purple powder coat finish — on 11-gauge steel
Dimensions
20-3/8" W x 16-7/8" L x 7" H
Adds 11-3/4" to the tank side once installed
Compatibility
Harbor Freight Series 3 27" or 42" Toolbox
What's included
Top and bottom tank mounts, ratchet straps, caster relocation hardware, plus any shelf, lead hangers, or welding top you choose above
Not included: tool box, tanks, machines. If you add a welding top, choose the size that matches your toolbox (27" or 42").
Installation note: Harbor Freight carts can vary slightly between units, so you may need to ream out a hole or slot for a proper fit. Leave all mounts loose until everything is in place, then tighten down.
