Seldén launched the new Deck Hardware range in September 2008. The BBB20 triple block features stainless steel ball bearings and stainless steel ball races. These bearings can take much higher loads than plastic and also plastic bearings deform and create ball to ball friction.
Grivory® Composite sheaves make for a harder surface hence improved wear resistance.
