The 2.6" Omni Block is the largest and strongest of all the Omni models. Increased in the thickness and size of key components result in an Omni with an 80kN/18,000lb MBS (minimum breaking strength) and a WLL(working load limit) of 20kN/4,500lbs based on a 4-1 safety factor. In addition to an integrated swivel, and push-button access to the sideplate, the 2.6" features a prussic-minding sideplate, and a countersunk sheave to improve interaction with rigging lines.
