- Multiple Fasteners
3” screws and 3/8" lag screws are utilized at all 2” x 4” joints. This eliminates a pivot point in the structure, minimizes leaning, and adds overall strength. Pre-drilling of all holes before securing minimizes cracking and splintering of the wood. Notice no splits from fastener attachment and all corners and edges are flush and square. Your friends will think you spent a fortune on your backyard playset.
