We offer a lag bolt mounting system consisting of a lag bolt, anchor, and washer to anchor into pavement or concrete. There are 4 anchor holes for our MLSB product line in each speed bump. For temporary situations, you can just lay them down or moor them in place with our GRK’s RSS™ Rugged Structural Screw. For our RK Series speed bump and speed humps, there are 2 anchor holes for each 24” long section.
