The Rock Exotica Omni-Block 2.0 Single is a high strength, 2.0" (51mm) sheaved, swivelling rope block. The Omni-Block combines a swivel and pulley into one device and incorporates a unique side plate that opens while the pulley is still attached to the anchor. The Omni eliminates the need for the swivel and carabiner, reducing overall measurement and pieces of equipment needed in the rigging system. The length of the Omni is significant when used in high-angle, confined space or other space-sensitive rigging environments. The smooth, ball bearing action of the Rock Exotica Omni-Block eliminates twisting of the rope in rigging systems. This precision fabricated alloy block has a unique button-activated release feature that allows instant access to the sheave for mid-line attachment. The milled alloy attachment eye is large enough to accept most carabiners and snaps. Accepts rope up to 13 mm. Made in the USA.
