T2 double lashing pulley 29 mm

More details

The Harken 29mm T2 lashing double block embodies excellence in performance and lightness for all your nautical maneuvers. Thanks to its lashing attachment system, which can be knotted or spliced, it adapts to almost any element of the boat, ensuring robustness and reliability in all conditions.

Sheave diameter: 29 mm
Overall length: 43 mm
Ultra-light weight: 23.5 g
Maximum line diameter: 8 mm
Maximum working load: 272 kg
Breaking load: 861 kg

The Harken 29mm T2 lashing double block stands out for its extreme lightness, a result of its metal-free technology, and its Delrin® ball bearings with a curved surface to improve sheave efficiency. This innovation significantly reduces stress on the cheeks and ensures optimal line alignment.

Lashing attachment system passing through the center of the block for better load distribution and increased safety
Absence of metal parts for unparalleled lightness
Composite guide keeps the line securely in place
Delrin® ball bearings for smooth operation even under heavy load
Versatility: ideal for traveler adjustments, mainsheet, vang, creating tackle systems or bridle systems
Spectra® line included for immediate and optimized installation

Perfectly suited for competitive sailing or pleasure cruising, it is a benchmark for all your maneuvers requiring reliable and ultra-light blocks.

Our tips for choosing

Workload and breaking load

Choose your pulley based on the workload it will have to handle and the desired gear ratio. The orders of magnitude vary depending on the support: 400 to 500kg for the mainsheet or cunningham of an 18-foot catamaran, 100 to 200kg for the mainsheet or downhaul of a 420 dinghy for example.

Coefficient of friction

Modern ball bearing pulleys offer a much lower coefficient of friction than those without balls and are recommended for maneuvers that require constant adjustment (mainsail sheet, downhaul, cunningham, spinnaker essentially).

Restraining force

For the mainsheet which is not always fully tightened, or even never on some boats which require constant adjustment (29er, 49er, Class A,...) as for the spinnaker sheet, favor automatic or non-automatic winch pulleys, which considerably save muscles and gloves thanks to a retention that can go up to 70% of the workload.

Sheave diameter

Choose the diameter of the pulley according to the diameter of the rope it will guide. For example, depending on the support and workload, a 40 or 57 sheave is very suitable for a 6 to 10mm mainsail sheet. For Cunningham or downhaul type maneuvers, 16 or 22 sheaves are suitable.

Material

Stainless steel, carbon, composite, it's essentially a matter of weight, with an impact on the price: it all depends on the importance you attach to it. If the pulley is to guide a cable, use aluminum sheaves which will be much more resistant than composite materials.
