20mm Single Tie-On block

Available with or without the soft shackle. 

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.

When attaching a Tii-on block you must feed the rope around the central axle and through the head of the block. Tii-On blocks rely on the correct attachment method to give them maximum strength.
