TIG rod holder brackets

These brackets are designed to securely hold PVC tubing with an inner diameter of 50mm and an outer diameter of 56mm, but there is a bit of flexibility to accommodate a slightly smaller size, possibly down by 1mm in the OD, for TIG welding filler rod. The top bracket features six-millimeter bolts that can be secured from the back using a nut, while also threading into the plastic without any issues. In contrast, the bottom bracket is designed specifically for holding the tube in place, with no need for additional fasteners. Both brackets boast a convenient slot that allows them to fit snugly over 2-3 millimeter steel or alloy flat bar, which has been welded onto my welding bench.
