Control 30mm Single Block with Fixed Strap

LEWMAR Control 30mm Single Block with Fixed Strap

The Lewmar Control 30mm Single Block with Fixed Strap is engineered specifically for handling hand-held loads aboard sailing dinghies and keelboats. Combining featherlight construction with robust load-bearing performance, this block delivers smooth, reliable operation across a wide range of sailing applications without adding unnecessary weight to your rigging.

Metal Replacement Technology (MRT) gives the block its weight advantage over traditional metal designs, while Long Fibre Technology in the fiber-reinforced cheeks provides exceptional impact resistance and durability. The stainless steel central race and ball bearings prevent deformation under load and maintain consistent, low-friction performance over time. The open-frame design ensures that sand and salt can be easily flushed out with fresh water, keeping maintenance effort to a minimum.

With a 30mm sheave diameter, a maximum rope diameter of 8mm, a safe working load of 200kg (440 lbs), and a breaking strength of 480kg, this block is well suited to medium and dynamic loads. At just 26g, it is an ideal choice where every gram counts. The fixed lashing eye strap mount provides secure, versatile attachment to spars, rails, and deck hardware.
