The patented Omni-Block 1.1 Swivel Single Pulley has proven its value through the years as a unique tool for rope rescue and rope access. Normally a pulley has been used in conjunction with a carabiner(snap link) and a swivel in many applications. The swivel is essential to correctly orient the pulley and prevent rope from touch the side plates of the pulley and greatly reducing efficiency. The Omni-Block Swivel Pulley has a built in sealed ball bearing swivel instead making rigging easier. This also makes the pulley system shorter which is beneficial in situations such as confined space rigging.

  • Aluminum Sheave: Aluminum sheave provides long term wear resistance while minimizing weight.
  • Ball Bearing Construction: Pulley sheave mounted on ball bearings for maximum efficiency.
  • CE Certification: Testing performed by an independent lab to ensure the product meets the appropriate specification.
  • Certification: Certified to EN 12278 – Montaineering equipment – Pulleys
  • CMC Machined: CNC machined construction from aluminum billet.
  • Integrated Swivel: Built in swivel allows the equipment to orientate itself and removes potential for unwanted torque
  • Large Diameter Sheave: Large sheave size preserves efficiency by minimizing the bend radius of the rope.

The Omni-Block 1.5in Swivel Single Pulley gives you the most flexibility to do your job safely and more efficiently than a traditional pulley.

The unique double locking sideplate gives you secure access to the pulley while you’re still connected to the anchor. With a traditional pulley, the pulley must be disconnected to remove or attach a rope. The Omni-Block Pulley allows a rope to be attached or removed without disconnecting the pulley. This is safer and also helps preventing accidentally dropping the pulley.

The 1.5 inch Omni-Block Pulley is the perfect size for use with work-at-height and rescue ropes. The 1.5 inch sheave works efficiently to help raise and lower heavy loads such as during a two person rescue. The single and double sheave pulleys are available with an aluminum sheave. The single sheave version is also available with a stainless steel sheave for use with wire cable. The single sheave version is also available with a shackle top for attaching into a semi-permanent location.

NOTE: The Rock Exotica Omni-Block Pulleys are available in 1.1 inch, 1.5 inch, 2.0 inch, and 2.6 inch versions.
