Rock Exotica Omni Block 2.0 Swivel Pulley w/ Drop Side Plates 1/2in Capacity. The Rock Exotica Omni Block is a small drop side pulley with a unique swivel top. This swivel action prevents any twisting action from the load transferring to the rope system. Great for speedline tasks. The side plate has a push button release for easy access to the 2.0in sheave. Strength: MBS: 8,093 lbs. 36 kN, WLL: 1,798 lbs. 8 kN, Rope capacity: 1/2in 13mm, Weight: 12.3 oz. The Omni’s ability to remain connected to the anchor while opening the sideplates allows the technician to install and remove lines from the pulley – in some cases with a single hand, simplifying a process that can otherwise lead to dropped equipment, fatigue, and attention taken away from job safety. To open the Omni sideplate, the user pushes the button and rotates the sideplate. A safety catch stops the sideplate from rotating completely open until the button is pushed a second time. The sideplate is easily closed by squeezing the sideplate into the body of the pulley. Two loud clicks are heard as the sideplate pushes past the button to close securely against the body of the pulley.
