DuraEdge® ProLoc™ Mound Blocks

The patented wedge-shaped design means 10° is everything. Excellent for construction or renovation projects. Use on your mound, batter’s box and catcher’s box. When laid properly, the angled sides at 10° overlap and compact more easily into one solid mass. The blocks are made of extruded, unfired red gumbo clay. Sold by the pallet only.

DuraEdge® ProLoc™ Mound Blocks

Most clay bricks have rectangular sides, but not ProLoc. The overlapping seams from our patented wedge-shaped blocks allows them to easily meld together. The downward pressure from tamping or rolling turns them into a solid clay sheet, making them perfect for renovation or construction projects around your mound, batter’s box and catcher’s box.
