– 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.

Perfect Little Sun Care Kit — Great for Travel!
Style: Original, Style: Original
I love this Sun Bum Road Tripper set! The travel‑sized products are perfect for tossing into my beach bag or carry‑on, and everything smells amazing. It has all the essentials you need for a day in the sun without taking up a ton of space. The quality is exactly what you expect from Sun Bum — gentle, effective, and reliable. This is such a convenient little kit for trips, beach days, or keeping in the car. Definitely a must‑have for anyone who loves being outdoors.

Travel size products, best sunscreen out there.
Style: Original, Style: Original
Great as always but picture is misleading a bit, this is the small travel size bottle not the full size. I should have read better, still like the set nonetheless of course. Heres a picture for comparison.
