Rock Exotica Omni Block 1.1" Double Pulley

The Rock Exotica Omni Block 1.1" Double Pulley combines a compact swivel and high-efficiency double pulley in one device, creating a short, space-saving unit that is ideal for arborist rigging, rescue systems and technical rope work. By removing the need for a separate carabiner and swivel, it keeps climbing hardware streamlined while still delivering smooth running and reliable load control.

A key benefit of the Omni design is the sideplate that opens while the pulley remains attached to the anchor. This allows you to install or remove rope without unclipping from your connection point, which is especially useful in high-angle, confined space or other tight rigging environments. The sideplate uses a two-stage, double-catch safety mechanism to help prevent accidental opening in use.

CNC machined from solid aluminium and built around sealed ball bearings, the Omni Block 1.1" Double Pulley offers an excellent balance of strength, efficiency and low weight. With a Minimum Breaking Strength (MBS) of 23 kN and a Working Load Limit (WLL) of 5 kN, it is well suited to professional rigging tasks where compact gear and clean system alignment are priorities.

Key Features

• Double-sheave swivel pulley for compact, efficient mechanical advantage systems
• Sideplate opens while the pulley is still attached to the anchor (when unloaded)
• Two-stage, double-catch safety mechanism helps secure the sideplate
• Integrated swivel reduces twist and allows the pulley to orient to the load
• CNC machined from solid aluminium for optimal strength-to-weight performance
• Sealed ball bearings for smooth, efficient running under load
• Short overall length – ideal for confined space and high-angle rigging
• Suitable for arborist rigging, rescue, rope access and stunt/industrial work

FAQs

What is the advantage of combining a swivel and double pulley?

By integrating the swivel and pulley into one device, the Omni Block 1.1" Double reduces the overall length of the system, removes the need for an extra carabiner and helps keep ropes and hardware aligned under load.

Can I change the rope without unclipping from the anchor?

Yes. The unique Omni sideplate allows you to install or remove the rope while the pulley remains attached to the anchor, as long as it is unloaded. This speeds up reconfigurations and is especially useful in tight or awkward positions.

What rope size works with the Omni Block 1.1" Double Pulley?

The pulley is designed for use with ropes up to 13 mm (0.5") in diameter, which covers most common arborist and rescue lines.

Is it suitable for professional arborists and rescue teams?

Yes. With a 23 kN MBS, 5 kN WLL and CE certification, the Omni Block 1.1" Double is widely used in professional arborist rigging, rope access, rescue, stunt work and other high-angle applications, when used within relevant standards and best practice.

Can the Omni Block be operated with one hand?

The sideplate and latch design allow experienced users to connect, open and close the pulley one-handed in many situations, helping to simplify rigging when working at height.
