MK7 Double-Pin Locker Black Unifiber UF590000040

Description:

The MK7 Double-Pin Locker is a compact, high‑security locking part engineered to secure boom connections on Unifiber monocoque booms. Its reinforced composite body and corrosion‑resistant stainless steel pins provide a durable, low‑maintenance solution for repeated rigging and heavy use in marine environments. The double‑pin design delivers positive mechanical retention and precise fit, reducing play at the connection and improving steering feedback and sail control. Low‑profile styling and a black finish minimize drag and blend seamlessly with modern carbon and aluminium booms. Easy to operate and service, the locker works standalone or combined with the MK7 Collar for additional compatibility with a wider range of Unifiber booms. Ideal for sailors who need reliable, long‑lasting hardware that holds under load and resists saltwater corrosion.
