Rock 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.

The Rock Exotica OMNI BLOCK double swivel pulley is a mix of the old and the new evolving from rotating swivel pulleys, called BLOCKS in years past.

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

Double pulley design.

The milled alloy attachment eye is large enough to accept most carabiners and snaps. The pulley features TWO 1.5 inch/38mm wheels / sheaves

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) diameter rope capacity.

Originally the first such pulleys were carved and fashioned from actual blocks of wood reinforced with metal banding to prevent the wood from splitting under load. Up to now, rescue pulleys have been the standard side swing plate models that involve rotating the side plate and the introduction of the rope into the sheave. Increased strength is cited as the main reason that life safety pulleys are designed this way.

  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
