Omni-Block 1.5 Double
This double block is ideal for creating mechanical advantage when lifting branches, pulling trees against the lean, or pre-tensioning a rigging line.
The Rock Exotica Omni-Block pulley has a built in swivel to help ensure that the rope fairleads in and out of the block so that all pulling force is placed squarely onto the sheave. This helps to preserve the breaking strength of the system and to prevent the rope from abrasion with the cheek plates.
Features & Benefits
- 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
Ratings & Reviews
Great product, but spend a bit extra to buy the 2.0.

I bought the 1.5 and the 2.0 Omniblock double pullleys for setting up 5:1 mechanical advantages. Both products are well constructed with features that facilitate easy setup. Having used both sizes, I’d recommmend the 2.0 over the 1.5 Omniblock. You get a little more strength out of the 2.0, it also has an prussik minding square corner for progress capture, and it’s not that much more expensive. The 2.0 does pair well with the 1.5 though if you want to use the two together to construct a 4:1 or 5:1. As with any mechanical advantage in pulling, make sure the rest of your equipment’s capabilities balance.
