Allen 20mm Single Tii-On High Load Block

Allen's Tii-On blocks feature a stainless-steel loop at the head of the block. This gives the Tii-On range maximum strength and reliability with minimal cheek separation when tied on and loaded up with a soft shackle. The stainless-steel head loop also ensures the block stays in the right orientation when being used.
