A quick-to-attach, high-strength swiveling rope block. Like Rock Exotica's popular swivel connector, this block eliminates twisting from rope rigging systems with smooth, ball-bearing action. Each precision-fabricated alloy block has a unique button-activated release feature that allows instant access to the sheave for midline attachment. Sideplate locks with two-stage, double-catch safety mechanism. The milled alloy attachment eye is large enough to accept most carabiners and snaps. These blocks eliminate twisting from rope rigging systems with smooth, ball-bearing action. Install and remove rope while still connected to the anchor. Integrated swivel allows pulley to orient while reducing gain. Connect, install and remove rope with one hand. CNC machined for optimal weight & strength. Tensile Strength (MBS) 17,985 lbs. (80 kN), WLL: 4,496 lbs. (20 kN)
