Specification Brand : HARKEN BulletPoint : SNATCH BLOCK BulletPoint1 : T2 blocks come in single and double configurations and can be tied, spliced, or lashed to almost anything BulletPoint2 : T2 doubles feature composite line guides that are integrated into the block head BulletPoint3 : They prevent the block from capsizing by pushing the lashing line to the outer edges of the sideplates. The 29, 40, and 57blocks feature composite sheaves that spin freely on Delrin ball bearings with curved bearing races. BulletPoint4 : They have no metal shackles or rivets, making them the lightest soft-attach blocks Harken has ever designed. All T2 blocks route the attachment line through the block head and sheave, decreasing the loads on the sideplates and acting as a safety backup for the system. Use for traveler controls, mainsheets and vangs, cascades, bridles, and other systems where small lightweight blocks are called for. BulletPoint5 : NARROW WIDTH WITH DEEP POCKET - For maximum storage in a horizontally narrow places such as mast or stern pulpit BulletPoint6 : COLOR OPTIONS - Available in two color combinations: Greyline (Antracita and Perla) & Navyline (Admiral Navy and Gris), allowing for personalized aesthetic choices.
