The Rock Exotica RE-P53 D Omni-Block 2.0in./51mm sheave (Double) P53 D for saleRock Exotica Omni block swivel/pulley patented devices revolutionized pulley use when they were introduced in 2005. The Omni-Block combines a pulley with a swivel and offers tremendous advantages.

Eye Dimensions:
* Inner dimension ( ID ) = 1.25 x 1 inch
* Profile = 3/8 inch

It can replace a conventional pulley, carabiner & swivel and is lighter, less expensive and saves valuable vertical space. It also allows installing/removing the rope while the pulley is still anchored.

While the standard version serves the needs of most users, the Omni is also available with some specialized options.

omniEach Rock Exotica Omni block swivel/pulley features a precision fabricated alloy block. A unique button-activated release feature that allows instant access to the sheave for midline attachment.

The milled alloy attachment eye is large enough to accept most carabiners and snaps. The pulley features a 2 inch/51mm wheel / sheave

The rotating swivel aligns the rope with the direction of pull making these swivel pulleys ideal for high anchor points or tripods. By combining the swivel with the pulley, overall length is minimized.

Sealed ball bearings are used for maximum efficiency

13mm (1/2inch) rope diameter capacity.

Rock Exotica has pioneered development into their 'bearing boss' manufacturing technique. This boss increases the diameter of the bearing hub and therefore increases strength. This development allows the pulley to be smaller and lighter with less material but still retain superior strength.

Breaking Strength: 2 x 18 kN = 36 kN

Working Load: 2 x 4kN = 8 kN

  Machined Pulleys: Why Rock Exotica Pulleys are special
Rock A solid block of aluminum will be CNC machined into a sideplate.

The sideplate is left thicker where it is important for strength. Lower on the pulley, material is cut away to make it thinner.

The axle is integrated into the sideplate to add strength and rigidity to the pulley, eliminating looseness or play in the plates.

The bearing and sheave fit snugly onto the axle portion of the sideplate.

A recess allows the screw to sit flush with the sideplate, unlike other pulleys which may use a rivet or a traditional bolt with a large head and nut protruding on both sides
