Collar MK7 Double-Pin Locker Black Unifiber UF590000004

Description: The Collar MK7 Double-Pin Locker is a precision spare-part designed to securely attach Unifiber MK7 boom heads to compatible masts and boom tails. Engineered for reliability in windsurfing rigs, the collar features a double-pin locking arrangement that delivers a positive, anti-rotation connection for confident sail control. Constructed from a durable, engineering-grade composite body with corrosion-resistant metal pins, the collar balances low weight with high strength for long-term performance in saltwater environments.
