Control 40mm Single Fixed Strap Block

Lewmar Control 40mm Single Fixed Strap Block

The Lewmar Control 40mm Single Fixed Strap Block is designed for sailors who demand lightweight, high-performance hardware for hand-held load applications. Part of Lewmar's trusted Control Block series, this single-sheave block combines advanced materials technology with a functional open design to deliver smooth, reliable performance in all sailing conditions.

Built using Metal Replacement Technology (MRT), the high-strength glass-filled sheave pairs with stainless steel ball bearings and a stainless steel central race to deliver a significant weight advantage without sacrificing load-bearing capacity. The stainless steel balls and ball grooves resist deformation over time, maintaining peak efficiency even with heavy use. The Long Fibre Technology open cheek design allows sand and salt water to be flushed out effortlessly, reducing maintenance demands and extending the service life of the block.

The fixed metal strap attachment point provides stability and a secure connection point, making this block well suited for applications where a non-swiveling connection is preferred. With a safe working load of 240 kg (528 lbs.) and a breaking strength of 800 kg, it handles the dynamic and medium loads commonly encountered in dinghy and keelboat sailing. The block accepts rope diameters up to 10 mm and is optimized for boats up to 30 feet in length.
