The Omni-Block combines a swivel and pulley into one tool, and incorporates a unique sideplate that opens while the pulley is still attached to the anchor. Traditionally, a pulley is connected to a swivel by a carabiner. However, the Omni eliminates the need for the carabiner, reducing length and pieces of equipment in the rigging system. The short length of the Omni is important when used in high-angle, confined space or other space-sensitive rigging environments. The reduced weight of the Omni will make hauling your gear easier. Additionally the Omni sideplate can be opened without detaching from the carabiner. Traditional pulleys require removing from the carabiner to change the rope. With the Omni, the user is able to do this while the pulley is still secured.

  • Install and remove rope while still connected to the anchor

  • Sideplate locks with two-stage, double-catch safety mechanism

  • Integrated swivel allows pulley to orient while reducing gain

  • Connect, install and remove rope with one hand

  • CNC machined for optimal weight & strength


The Omni Swivel Pulley is made the same unique way that many of Rock Exotica products are made—from solid material. The design and function of the pulley require a strong core from which the sheaves, side plates, and swivel top must connect. For this we rely on the capability of our state of the art machining centers to take a solid block of aluminum and cut away material to create this integral part.

With precision available only on such a machine, the block of aluminum is transformed into an axle, head piece, becket, and release button housing all in one. The result is a pulley that is lighter, stronger, and more compact than those made by traditional methods and stamped parts.

Omni 2.6 ReviewReview by Alan
Overall Rating
First, there is no other block out there that is better qualified for use as a quick, easy to install, mid-line redirect. None. They don't exist, especially considering how flexible the Omni is. As the tree came apart, I transitioned into using it in a "Span Rigging System".

A traditional rig system has the working end of line threaded through one or more blocks and anchored to a tree part that is being cut and lowered. A span rig differs from a traditional rig in that the working end of the line is anchored to a tree part that will remain. The wood being cut out has the sling of the Omni Block girthed to it, and the Block itself is connected to the section (span) of line between the anchored end and the previous block.

The Omni is excels in this application since it can swivel, and it can so quickly be attached to the wood being rigged and the span of line that will "catch" it. I absolutely LOVE LOVE LOVE this block. Love it! (Posted on 8/12/2015)
