New product! We will be shipping these units out by February 16th, 2026.

This kit is for the top mount ratchet strap and bottom mount to secure the tanks. The shelf, lead hangers, and platforms are sold separately.

The top mount has ratchet straps to hold your bottles securely and 3 places for tig rod holders. The holes measure 2-1/8" to easily fit in your 2" tig rod holder.

This welding cart kit is made for the Harbor Freight 30" single drawer cart. The kit is setup for a single  7" to 9-1/4" tanks and it's built out of 11 gauge steel for strength.

The kit uses the existing holes on the tool box (you may have to ream out some holes). You will relocate the casters to the new bottom deck with the included the included hardware. All other mounting hardware can be found from the tool box itself. 

Dimensions: Once installed, the kit wall add 11-3/4" to the tank side of your cart.

*Some pictures show optional accessories like lead hangers and shelf. They are not included in this purchase. We try our best to give enough adjustment in the holes and slots so you don't have to enlarge holes or grind on your cart. Harbor freight carts are not always exactly the same and you may have to make small adjustments. It's always best to leave your cart mounts loose until everything is in place and then tighten everything down.

This kit is raw steel and unpainted.

Tool box and gas cylinders not included.
