The Lally Lock Beam Plate is a great option for wider beams. It is 8" long and made from 1/4 " low carbon steel. The plate has either one keyhole or one 3/8" hole located in each corner and the plates are packaged with GRK screws. To accommodate any Lally Lock Column diameter, this plate has a 19/32" counter sunk hole in the center of the plate to accept a 1/2 " bolt.
