Aluminum tube is the hangar, the smaller steel tube fits inside as the "drawer slide". Set depth on table saw to cut a channel centerline the full length. Drill 4 holes on the opposite side to attach under cabinet.

Drawer. Drill holes along the length for tool hanging hooks (machine thread). Use a straight rod with a nut (for hooks) hotglued to rod to fish into the tube so you can thread the hook to the nut. Use RED loctite on nut and hook threads to allow it to swivel but never unthread.

Now you have a sturdy rail that slides in and out and removable. Go to larger size tubes if you need to hang heavier stuff.

Larger outer tube should be aluminum since you can cut it with a wood blade on table saw and not mess up the blade. You can shift the fence to make the groove wide enough for the bolts to slide easily in the gap.
