About this detail

A quarter-inch galvanized knife plate inserts into the top or mid rail of the guard assembly, with open pipe ends left as detailed. Two one-half-inch diameter ASTM A325 galvanized bolts with short slots secure the knife plate to a one-quarter-inch galvanized mount plate. The mount plate welds to a four-by-four-inch hollow structural section steel column with an one-eighth-inch fillet weld applied on three sides. Sealant is applied all around the perimeter of the connection.
