b'Line/Wire High300304Strength Blocks 308Lightweight, low-friction wire blocks carry wire halyards and high-strength control lines on boats of all sizes. High-load composite bearings carry axial loads. Hard Lube-anodized sheave for strength andHigh-load composite bearings handle corrosion resistance.wire and high-strength line.25 mm (1") wire blocks use low-friction thrust washers. 38 mm (1.5") and 51 mm (2") wire blocks feature466sideload balls between the sheave and the sideplate to minimize friction from unfair leads. 466 features a forkhead and becket making it useful for vangs, halyards and control lines. Use for:Wire halyardsVangs Sideplates rotate to insert preswaged/Control lines Nico-pressed wire fittings.30254 mm (2 1/8") 32030675 mm (2 15/16")31094 mm (3 11/16")302306310Cutout302 11 mm (13/32") x 39 mm (1 17/32")306 13 mm (17/32") x 59 mm (2 5/16") 310 14 mm (9/16") x 73 mm (2 23/32")30122 mm (7/8")30532 mm (1 1/4")30941 mm (1 5/8")301 312305 313309 314LightningPhil Page PhotographySheave Shackle pin Max wire Max line Maximum BreakingPartWeightworking load loadNo. Description in mm oz g in mm in mm in mm lb kg lb kg300Single1251283/1653/3225/3210004542000907 4 301Cheek*1251.25353/3225/32410004542000907 302Through-deck*1251283/3225/32410004542000907 304Single1 1/2382.75781/461/833/165150068030001361305Cheek**1 1/2383.25921/833/165150068030001361306Through-deck*383.25921/833/165150068030001361 1 1/2 86 308Single2515.251495/163/1651/4200090740001814 309Cheek***25161703/1651/46200090740001814310Through-deck**2515.751633/161/46200090740001814 5 312Single/becket1251.25353/1653/325/32410004542000907 2 313Single/becket1 1/2383851/461/833/165150068030001361314Single/becket2515.751635/163/161/46200090740001814 85 320Ferrule head1 1/2383851/833/165150068030001361466Single forkhead/becket1251.02293/163/3225/32410004542000907 5 Fasteners included. *#10 (5 mm) RH fasteners. ** 6 mm (1/4") RH fasteners. *** 8 mm (5/16") RH fasteners. 41'
