Safety & Rescue
The AZTEK Pulleys, also known as Omni-Blocks are engineered from a solid block of aluminum to maintain strength. The pulleys come together in either a blue/orange set or the black set with 'A' and 'B' lasered on them. This coding is used to help set them up in the 4:1 configuration when used with Sterling's 6mm ratchets. The Omni-Blocks are also prusik minding pulleys and can accept up to an 8mm rope.
