Our Tii-On blocks feature a stainless-steel loop at the head of the block. This gives our Tii-On range maximum strength and reliability with minimal cheek separation when tied on and loaded up with a Tii-Shackle. The stainless-steel head loop also ensures the block stays in the right orientation when being used.
Available with or without a Tii-Shackle (soft shackle).
Fitting Instructions –Tii-On blocks rely on the correct attachment method to give them maximum strength.
When attaching a Tii-on block you must feed the rope around the central axle and through the head of the block.
When possible, double Tii-on blocks should be attached with a crossed/ through threaded line. (see pictures for example).
This is very important, as it keeps the line load pulling the side cheeks together. Only use a non-crossed Tii-Shackle on low-load applications.
