I depend on my pipe clamps for most projects, which means I constantly have to move them around the shop (or trip over them). The simple caddy I built makes moving and storing those heavy clamps easy.

I built mine for 24" clamps, but you can resize all the parts to accommodate longer (or more) clamps. The lengths of 114 " I.D. PVC pipe slide through the holes in the top and fit over 1  14 x1" dowel attached to the base with screws. After securing the pipe to the dowel with screws and attaching casters, your pipe-clamp caddy will be ready to roll.
