75mm aluminum stand-up block Harken

Specially developed to meet the requirements of high-performance racing and cruising yachts. The 75mm aluminum stand-up block Harken combines lightness and robustness to optimise the adjustment of common manoeuvres. Its 75 mm sheave, made from 6061-T6 aluminium with PTFE treatment, ensures perfect glide and increased resistance to UV and marine wear. What’s more, the Derlin balls on the sheave are UV-treated.

Equipped with a low-friction Torlon® bearing system, this block reduces friction to a minimum for fast, precise operation, even under heavy loads. The design of the 6061-T6 aluminium and PTFE-treated flanges and sheave guarantees exceptional durability. And it can be quickly dismantled with an Allen key for easy maintenance, essential for intensive use at sea.

Compatible with sailboats such as the Nautitech 482, this block allows a 45° angle and adapts to standard attachment systems thanks to its included padeye. Whether for quick gybes or fine tuning, it ensures safety and fluidity, even in the most demanding conditions. The Black Magic block has a high working load of 2268 kg and a breaking load of 4536 kg. This makes it a major asset for your outings at sea.

What’s more, this block is a top-of-the-range accessory that combines precision, durability and lightness. It’s ideal for the most demanding sailors.
