Description

The Omni-Block 2.0 Single from Rock Exotica combines a swivel and a rigging block in a compact tool. The unique side plate can be opened with a push-button while the block remains attached to the anchor, saving time, reducing equipment, and optimizing space in confined rigging environments.

The Omni-Block 2.0 Single is an upgraded version with a 2-inch sheave (50 mm) for improved bend radius and reduced rope wear. The integrated swivel ensures the rope runs correctly in and out of the block, maximizing breaking strength and preventing abrasion against the side plates. Made in the USA with CNC machining for optimal strength and low weight. Perfect for arborists, high-altitude work, and confined spaces.

The safety mechanism features a two-stage double-detent: Press the button and rotate the side plate – a safety catch stops it until the button is pressed again. Close by squeezing the side plate against the body; two clear clicks confirm locking.

Features

Install and remove rope while the block is connected to the anchor
Side plate locks with a two-stage, double-detent safety mechanism
Integrated swivel orientates the block and reduces gain
Connect, install, and remove rope with one hand
CNC-machined for optimal weight and strength
Prusik-compatible side plate (prusik-minding)
Push-button access to the side plate
