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 halyards Sideplates rotate to insert preswaged/Vangs Nico-pressed wire fittings.Control lines30254 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 314 Medora Media / Doug WakeSheave Shackle pin Max wire Max line Maximum BreakingPartWeightworking load loadNo. Description in mm oz g in mm in mm in mm lb kg lb kg300Single1251283/165/32410004542000907 53/322 301Cheek*1251.25353/3225/32410004542000907128 302Through-deck*1253/3225/32410004542000907 304Single1 1/2382.757833/165150068030001361 1/461/8 305Cheek**383.25921/83/165150068030001361 1 1/23 3061 1/2383.25921/833/165150068030001361 Through-deck* 23/16 308Single515.251495/16851/46200090740001814 309Cheek***25161703/1651/4690740001814 2000 310Through-deck**25.7516351/4200090740001814 513/166 312Single/becket1251.25353/1653/3225/32410004542000907313Single/becket1 1/2383851/461/833/16150068030001361 5 314Single/becket2515.751635/163/161/4690740001814 852000 Ferrule head1 1/23838535150068030001361 3201/83/16 466Single forkhead/becket125293/1653/3225/32410004542000907 1.02 Fasteners included. *#10 (5 mm) RH fasteners. ** 6 mm (1/4") RH fasteners. *** 8 mm (5/16") RH fasteners. 42'
