The A-frame bracket makes building a swing set easier than ever. You'll be amazed by how quickly you are able to complete your project. Use it for your kids' swings, a porch swing, a tire swing or any other swing you dream of. This is the strongest, safest and easiest system on the market today; you simply slide the wood into the brackets and screw the included lag bolts into the pre-drilled holes, no cutting or measuring necessary. Each one piece steel bracket features a rust-resistant green powder coating and pre-drilled holes for easy installation. The bracket is designed for use with 2 4"x4" beams and 1 4"x6" beam; you may want to take the bracket with you when purchasing your lumber to guarantee a proper fit. The bracket comes with 5/16 x 3-inch lag bolts with washers. The brackets are sold individually so that you can order as many as you need to build your own custom swing-set design just the way you dreamed it! With these brackets you will be building a structure that lasts, bringing ever-lasting satisfaction and enjoyment from your handiwork.
