The Sheet/Forestay Attachment is specifically designed for 10mm or 11mm round booms and is ideal for high-load applications such as sheet and forestay attachment points. Made from stainless steel, it features a 3.3mm Ø hole, perfect for use with a Zed Hook (Ref. 87Z). The attachment is carefully engineered to handle significant stress while ensuring smooth operation.

The hole is mechanically de-burred and tumbled to eliminate any rough edges, preventing damage to the sheet as it passes through. Its profile shape is designed to minimize the risk of snagging lines, offering a reliable and efficient solution for your rigging needs.

For applications with lower loads, consider using the lighter and more economical Boom Band with Eye (048-11x) equivalent for a more cost-effective alternative.

Tungsten putty 25g (piece)

Tungsten putty is a firm, malleable material made from tungsten powder and a polymer binder that will tend to harden when submerged into cold water after shaping. This results in a material that is 30% heavier than lead, reusable, non-toxic, and requiring a smaller amount to have the same benefits as lead. Tungsten putty leaves no sticky residue on hands, clothing or gear, is lead free, and therefore safer for the user and the environment.

Ideal for adding weight to masts by breaking it into small pieces to get an accurate weight on rigs.

Formed from 1.2 mm Ø stainless steel wire, 15 mm x 6 mm, 10/pack. Hole is in the same plane as the hook.
