Product Information
Core Blocks™ are a true all round solution. A tuned 2-stage bearing system provides excellent performance across the full working load range with an integrated thrust bearing feature and the resilience to handle high dynamic or static loads. Acetal sheave, alloy cheeks and stainless fixings complete the durable package. For reliability and a long service life, these blocks are the right choice for sheets, halyards and control line applications for cruising and racing.
Universal Bearing
Dynamic and high static load performance
The Ronstan Universal Bearing incorporates our proven 2-stage bearing system
Stage 1 - Under moderate loads, Acetal ball bearings ensure minimum friction.
Stage 2 - Under heavy loads, where deformation of ball bearings alone would result in increased friction, a sliding Acetal bearing on a polished stainless steel race takes over, maintaining low friction performance.
Additionally the ball bearings are configured to act as a thrust bearing between the sheave and cheeks, preventing the sheave from rubbing on the cheeks and causing friction when the line lead in and out of the block isn’t perfect. Particularly important for cheek blocks.
Alloy cheek plates
Block cheeks are manufactured from the highest quality alloy for maximum strength. Material optimization and the cut-away design minimizes weight and allows easy fresh water rinsing of salt and debris from the bearings. Cheek design has been further styled with flaring at the block throat and reduced gap between the cheek and sheave, minimizing rope wear.
Applications
Ideal for mainsheet, halyard and spinnaker sheet applications on boats to 12m (40ft).
Various control line applications on larger yachts.
Alloy sheave models are available for use with wire.
Materials
Sheave: U.V. stabilized Acetal or anodized aluminum (AW models)

Good TP
Size: 9 Mega Roll
Nice paper. It doesn't have lint like other papers. Fairly strong for natural TP. It is not economical for larger families though. I would buy it for a 2-3 person household. It's not super-soft, but it's doesn't feel cheap.

Small rolls, but not to scratchy
Size: 24 Double Rolls (2 Ply)
We've been trying different bamboo t.p. brands. This one is not bad, but the rolls are quit small, so while this package has 24 rolls, they don't last long. The paper itself is pretty good. Not quite as soft as we'd like, but not the sandpaper of some others we tried.

Lasts longer than average roll
Size: 24 Double Rolls (2 Ply)
Ok. I have to admit. This toilet paper checks out all the boxes. Its very soft. It really DOES last longer and it's toxins free. Great stuff.

Safe and reliable TP for the family
Size: 24 Double Rolls (2 Ply)
This brand is the best and softest bamboo TP I have purchased. This is a staple in my house, its durable and longer lasting than other brands I have tried. Cost of this is cheaper than most others as well, bonus. Highly absorbent. Package size it suitable for the price. Also good for septic systems

Not my favorite
Size: 24 Double Rolls (2 Ply)
I've tried quite a few bamboo toilet paper brands, and this isn't a favorite. Even at 2-ply it's thin. It has a good texture while being soft, and lint free as advertised, but I find we use more of this brand due to it being thinner. It has a lower price point than some of the premium brands, but a classic case of "you get what you pay for" and since we use more it doesn't really save any money anyway. Also it says plastic free, but comes in plastic packaging - it's not clear if it is eco-plastic/ biodegradable or not. It's not a bad product, and everyone likes something different and has their own priorities, but personally I won't reorder.
