Everything you need to construct a free-standing A-Frame swing set is included in our pack of 2 A-Frame Swing Set Brackets and 2 sets of A-Frame Bracket Hardware. Made of heavy-gauge steel with 100% welded joints, these are the strongest brackets available, ensuring a durable and stable swing set. The swingset middle bracket offers a wide variety of swing positions for a backyard upgrade. Innovative swing set brackets support force points with added triangular hardware, reinforcing the structure to strengthen the legs and beam. This results in a stronger load-bearing capacity with no deformation. Do not attempt to force the wood into the wooden swing 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 planed down to produce a comfortable fit. Lumber is not included in this swing set bracket kit.
