The Lockjack is an advanced mechanical split-tail that, unlike any climbing knot, allows free passage of the climbing line for near-effortless ascent and limb-walking activities. Whether you prefer body-thrusting your line above or footlocking your line below, or a foot ascender, the Lockjack advances hands free! For body-thrusting, the Lockjack requires only a few pounds of rope beneath to drain slack through the device, leaving hands free to advance up the line above without need to manually manage any knot. Once in the crown, this feature allows the climber to hand-over-hand their slack while moving toward the anchor point as the Lockjack magically drains the incoming line! Most buyers prefer the swivel-attach model, which compensates for twisting activity and provides optimal handle position at all times.
