The Omni Block 2.6 single pulley has an increased MBS of 80kN with 20kN WLL. It’s unique design, like all other Omni Black Pulleys allows the user to install and remove rope while still connected to the anchor. The sideplate locks with a two-stage, double-catch safety mechanism. The inntegrated swivel allows pulley to orient while reducing gain. Made in the U.S.A.
