The GateHands Tube-Gate Latch System is available in three models (to accommodate overlapping, side-by-side, and single gate styles) and three sizes (to accommodate 1 5/8-, 1 3/4-, and 2-inch-diameter pipe). For the overlapping and side-by-sides, the latch with a hasp affixes to Gate 1's second-down horizontal pipe, while the other latch affixes to Gate 2's fourth-down horizontal pipe; this configuration will keep the gates both straight and secure. For the single gate, the latch adjusts for up to a 12-inch gap and doesn't require that the attaching post be straight. To install, one fits the U-bolts over the pipe, tightens the nuts, and insets the provided locking pin.
