The 40mm single tii-on block is our go-to dinghy mainsheet block. Also ideal for dinghy jib and spinnaker sheeting systems as well as keelboat control lines.

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 soft shackle. The stainless-steel head loop also ensures the block stays in the right orientation when being used.

Available with or without a soft shackle.

Becket – The large central rivet not only reduces the overall weight but also offers a rope friendly attachment, perfect as a tie-off point when being used in a cascade system.

Bearings – Dynamic Blocks feature our patented bearing system which uses twin rows of stainless-steel ball bearings running on a stainless-steel rail. This provides a superior load-carrying ability and longevity when compared to other bearing systems which run on a plastic rail.

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, 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.

When using a Tii-Shackle, when possible cross the lines. Only use a non-crossed Tii-Shackle on low-load applications. See the picture above of the block attached to a lacing eye for example on how to cross the Tii-Shackle.

    Love it
    Color: White, Color: White
    This is so beautiful! It's very good quality. I got this for my daughter to keep her jewelry in and it's perfect. It has three floors, the top opens for a ring compartment, and the sides open for necklaces. All the compartments have pink velvet on the inside. I really like the size of this, not too big but not too small. It fits perfectly on an over the toilet shelf or the bathroom counter. A great but with a decent price.

    Beautiful Jewelry Storage
    Color: White
    A lovely jewelry box! Definitely worth the price. I love the little mirror inside, because it is useful when putting on my earrings. I do wish that one of the drawers was divided into smaller sections for bracelet storage, but overall the storage is amazing. Love the hooks for necklaces and the ring storage. It’s very pretty with the pink lining. Gorgeous for any space, and would make a lovely gift
