The Kreg Pocket-Hole Jig XL (KPHJ920) is a heavy-duty 5-piece joinery kit designed specifically for large-scale projects using 2x4 and 4x4 dimensional lumber. This extra-large jig features hardened-steel drill guides that produce joints with twice the strength of standard pocket holes. Its modular, twist-apart design allows the dual drill guides to be used together for fixed spacing or independently for custom applications. The kit includes an XL-stepped drill bit, a 6-inch #3 square driver bit, an easy-set stop collar, a hex wrench, and a clamp pad adapter. Equipped with GripMaxx anti-slip material and sliding locking stops for material thicknesses of 1-1/2 inches and 3-1/2 inches, this tool ensures precise, secure drilling for building outdoor furniture, decks, and structural framing
