The 44mm aluminum mastbase block<\/strong> is an essential piece of equipment for optimising halyard routing at the foot of the mast on your sailboat. Its lightweight<\/strong>, low-profile<\/strong> design allows the blocks to be compactly grouped in a small area, ideal for efficient, ergonomic installation on a modern yacht mast.<\/p>\n

Designed to offer maximum resistance to transverse loads, this block features a high-performance bearing system combining a PTFE<\/strong> composite bearing and side bearings. This technology reduces friction and ensures smooth, efficient operation, even under high tension. This halyard block has a working load of 340 kg <\/strong>and a breaking load of 680 kg<\/strong>.<\/p>\n

The 44 mm sheave<\/strong> is made from hard-anodised aluminium, a material renowned for its strength and resistance to corrosion, ensuring extra durability in demanding marine conditions. The rounded cheeks have been specially designed to prevent premature halyard wear, ensuring better rig retention.<\/p>\n

Compatible with the Nautitech 482, this block is an ideal choice for yachtsmen and sailors looking for a high-performance, robust<\/strong> and reliable<\/strong> piece of equipment for their halyard rigging<\/a>.<\/p>\n
