The Steel Base Blocks are designed to fit all metallic Lee presses. We have a template on our website to facilitate mounting the Load-All to the Lee Reloading Stand or Bench Plate, however you will need to mount the press to 3/4" plywood or a hardwood block cut to the proper size. See the attached PDFs for a fit guide and block template. The template is full size, so you can simply tape or glue it down to the wood and saw it out. It is important to drill the two lock holes in the wood block and thru the top plate or base plate, as the load on the wood block is cantilevered over the edge of the reloading stand/bench-plate, running a 1/4" bolt through the lock hole will insure the Load-All will stay in place during your loading session.
