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.
Fully articulated stand-up
Stand-up models have a low profile linkage that provides full rotation and articulation. A high strength precision cast padeye minimizes the footprint and a dedicated rubber boot ensures the block is held upright when not loaded.
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.

Great find!
I used this on a prom bouquet and it came out beautiful. Soft dainty sparkles for the perfect shimmer. A convenient small aerosol container that I gave to my son’s girlfriend in case she wanted to touch it up or use it herself. I love the fact that it’s still stuck on my crafting desk. Very affordable and it served its purpose plus some!

The ultimate festival glow in a bottle!
**5.0 out of 5 stars - The ultimate festival glow in a bottle!**
If you want to be seen from space (in the best way possible), this holographic silver spray is exactly what you need. I bought this for a rave, and it exceeded all my expectations. Unlike other glitters that just look like silver specks, this has a true holographic finish that catches the light and shifts colors beautifully every time you move.
The "quick-drying" claim is no joke. I was worried about it feeling sticky or transferring onto my clothes, but it set in about 60 seconds and stayed put. I sprayed it on my hair, my collarbones, and even over my makeup, and it lasted through hours of dancing without fading or raining down "glitter snow" all over the floor.
I also love how fine the mist is. It’s a very even, shimmering distribution rather than big, chunky blobs of glitter, which makes it look much more high-end. It washes out of hair and off the skin surprisingly easily with just standard soap and water, too. If you’re looking for that perfect, effortless sparkle for a concert or party, this is the one to get. Just a fair warning: once you start spraying, you'll probably want to cover everything in it!

Delicate pretty glitter, but pungent
This leaves a beautiful tiny glitter. Beware this glitter will get everywhere and it’s highly perfumed. If you’re smell sensitive or want to avoid getting too much mess, I highly recommend using the spray outside.
