– 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.

Charming little solar accent for the garden
This angel statue is absolutely adorable and adds a sweet touch to my front flower bed. The sculpted details are surprisingly refined for such a compact piece, and the solar panel charges well throughout the day to provide a gentle glow at night. The light isn't overly bright, but it creates a lovely ambient effect that's perfect for pathway edges or nestled among plants. The statue is smaller than I initially expected based on the photos, but that actually works in its favor—it's easy to tuck into various spots without overwhelming the space. I've had it outside for a few weeks now through some rain and wind, and it's held up beautifully with no fading or damage to the finish. The solar function has been consistent, lighting up reliably each evening. It's a thoughtful piece that would make a great gift, and the compact size means it works just as well on a small balcony as it does in a larger garden. If you're looking for a subtle, charming accent that requires no wiring or maintenance, this little angel statue is a winner.

Resin
This 8 inch tall resin angel will add the whimsy to your garden. It is solar powered to charge during the day so the butterfly will shine at night. Very durable and waterproof. This angel is very realistic with its wrinkles and dimples. I would recommend this cute little angel, but I feel it is a little overpriced.

Great product! Wish I had found it sooner!
Perfect solution for our umbrella stands! It is slightly taller than original pipe on stand (this is a plus!) Has two bolts instead of one (Another plus) to help secure the umbrella better. Has two rubber reducers to fill in gap around the umbrella pole. Only issue is the shank on the bolt is too long (bolt that secures pipe to base). Extra bolt was too short. We are purchasing another one for another umbrella stand. Great price for the product! And was easy to install, keeps the umbrella straight and upright!

Good quality, but likely holds water.
Good quality and was easy to install on base with two bolt lengths provided. I modifed by drilling a small hole through the base of the pole mount so that water can drain out. I have previously ended up with a rotten wooden umbrella pole because the pole mount held water!
