– Unique and iconic design
– The deep groove allows the pulley to rest on the deck without wearing out the rope
– The holes all around the periphery allow you to attach the cord which will prevent the rope from coming out of the pulley and connecting the KB to each other
– 2 versions available. KB = roller bearings. KBC = self-lubricated bearing (recommended for the heaviest loads)
– Dimensions & minimum weight
– The textile attachment through the center of the pulley ensures a weight saving of up to 50% compared to conventional pulleys (loaded of equal work).
– Its round and flat design allows it to be often installed on a flat deck
– Ultra versatile : the KB are coupled to each other thanks to perfectly ergonomic connecting pieces
– The large central space allows many possibilities of cascade assembly
– Common applications : Double backstay, mast foot, flat deck hoist, line return, lazzy bag, …
– If the sheave breaks, the circulating rope is captive to the transfilage. Although the pulley no longer ensures the circulation of the rope, the rope linkage point of attachment of the pulley remains.

Beautiful, comfortable sneakers
Size: 13 Little Kid, Color: Black/Rose Gold
Great sneakers. Easy for my six year old to get on and not too tight that she struggle. That tends to happen with other sneakers like this. Colors are bight and on point.

Love those sneakers but the longevity is questionable.
Size: 5.5 Big Kid, Color: Navy/Lavender
My daughter loves the look and no shoelace design, but maybe she is just a tad too active and these shoes usually last less than 1 year. Luckily unless you decide to hand its down to your next child, longevity is usually not my top concern as they will outgrow the size before it broke.
