Harken Fly 18mm Single Block

With the new T18™ block's 125 kg (275 lb) working load and and 7.2 g (0.25 oz) weight, this tiny block is our lightest soft-attach. It installs anywhere and articulates for perfect lead angles. A stainless grooved race and stainless balls vastly increase working load, while the non-load-bearing components are made of lightweight and impact-resistant composites. 

The 18 mm block accommodates lines up to 5 mm (3/16") and includes 1 meter (3.28 ft) of 1.8 mm (1/16") Dyneema® for lashing. The T18 bearings and inner race are made with 316 stainless steel while the fiber-reinforced nylon resin sideplates reduce weight.
