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

This is a welding cart kit for the Harbor Freight Series 3 15" End Cabinet. It's built out of 11 gauge steel for strength. The kit can accept up to 9-1/4" tanks. The top mount has ratchet straps to secure your bottles and 2 places for tig rod holders. The holes measure 2-1/8" to easily fit in your 2" tig rod holder.

(Casters)

This kit does not include casters. We reduced the price of the original kit so you can purchase casters directly from Harbor Freight so they match the casters on other carts. We will still provide the bolts to attach the casters. Below are the links to the swivel casters and the rigid casters. The top mount will need to be secured with rivets, sheet metal screws, or rivnuts. (we will include 2-5/16" rivnuts).

*We try our best to give enough adjustment in holes and slots so you don't have to enlarge holes or grind on your cart. Harbor freight carts are not 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.
