Availability: Out of stock SKU MHP58 Categories , , Tag

The Material Handling Omni 4.5″ is designed for heavy load lifting and as an arborist impact block. It is the strongest Omni-Block pulley with a Working Load Limit (WLL) of 6000 lbf. The MHP58 features a prusik minding sideplate and push-button access to open the sideplate to install rope. Whether used in a hoisting system with a capstan winch or in general industrial rigging, this rigging block provides a high-strength and lightweight solution needed for arborists, industrial riggers, and tower work.

The Omni-Block combines a swivel and pulley into one tool, and incorporates a unique sideplate that opens while the pulley is still attached to the anchor. Traditionally, a pulley is connected to a swivel by a carabiner. However, the Omni eliminates the need for the carabiner, reducing length and pieces of equipment in the rigging system. The short length of the Omni is important when used in high-angle, confined space or other space-sensitive rigging environments. The reduced weight of the Omni will make hauling your gear easier. Additionally the Omni sideplate can be opened without detaching from the carabiner. Traditional pulleys require removing from the carabiner to change the rope. With the Omni, the user is able to do this while the pulley is still secured.
