Our easy-installation A-frame 90-degree middle swing set bracket offers limitless swing positions, perfect for any DIY enthusiast aiming to create the ultimate backyard playground set. Constructed with the same high-quality materials as our original end A frame swing set brackets, whether you prefer 2, 3, 4, 6, or more swinging positions, this bracket accommodates them all! Build a freestanding backyard playset effortlessly with our 90-degree A-frame middle bracket, designed to fit kiln-dried lumber. We recommend using two 4" x 4" legs (true measurement: 3-1/2" x 3-1/2") and one 4" x 6" top beam (true measurement: 3-1/2" x 5-1/2"). The bracket openings measure 3.62 inches x 5.62 inches, respectively. We strongly advise measuring your lumber before purchase to ensure it meets these specifications. Warning! Do not force the wood into the bracket; the lumber should slide in easily with a snug fit. If your boards are too large, we recommend planing them down for a comfortable fit.
