Our bracket is designed to fit kiln-dried lumber. We recommend using two 4" x 4" legs with a true measurement of 3-1/2" x 3-1/2" and one 4" x 6" top beam with a true measurement of 3-1/2" x 5-1/2". the bracket openings measures 3-5/8" x 3-5/8" and 3-5/8" x 5-5/8", respectively. We strongly suggest measuring your lumber before purchasing to ensure it meets those specifications. Warning! do not attempt to force the wood into the bracket. The lumber should slide into the bracket easily with a snug fit. If your boards are too large it is recommended that the wood be planned down to produce a comfortable fit.
