Base Plate. Attach base plate to any flat surface via four mounting holes that are countersunk for drywall screws or flathead machine screws. Add Base Plate Blocks and you have a solid starting point to build off of. Base plates are 3/8 inch thick, drilled and tapped for 1/4-20 fasteners. This Base Plate is compatible with the 15 mm, 375, 500 and 750 series Base Plate Blocks.

Brian has proven time and again that there's ALWAYS room to improve on the simplest thing. Now the baseplates have nicely milled countersunk holes in the 4 corners.
Also, there are counterbored base plate blocks so they can be used either horizonally or vertically.
Many thanks Brian! (now I'll need a bigger Berkey Box!)
