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.
Universal head
The head assembly incorporates a brass bearing washer to provide smooth 360° rotation of the post and shackle. A set screw arrangement allows the head to be locked at 0° or 90°.
Shackles are high quality forged grade 316 stainless steel.
Acetal & aluminum sheave options
Selected models are available with an aluminum sheave which has a deep groove profile specifically made for use with wire.
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.

Unbelievable Value: Durable and Adorable! My Pup Loved Then Instantly!
Color: Multicolour20
My brand new pup LOVED THESE INSTANTLY! I He’s 10 months old and still in that “gotta chew on everything “ stage: those puppy baby teeth can really get itchy. I love that these toys nontoxic but they are definitely tough. When I opened the box I wasn’t overwhelmed with the small of chemicals. It’s a similar, clean feeling quality as something I would have purchased for my son back in the day. The variety of shapes and sizes is perfect. All the little nubs on the silicones are also in various sizes from larger to fine and really help him get those tough hard to reach slots. I would definitely give them an A+ on appeal and durability. My GSD played with one for 30’ minutes and it was still in tact. He can rip pretty much anything to shreds in under 5 minutes…I’d call this purchase a win-win. Can’t beat the value for the money. Material is quality. They’re cute and adorable. Can’t beat it!

Toys For Puppies
Color: Multicolour20
This package is suited for puppies and it is priced right. 20 toys for 20 dollars and my little guy loves them. No outlet pet store will sell you this amount for the price. Great buy.

Color: Multicolour20
My puppy loves to pull the toys out of this box and he especially loves the rope he likes to chew on it and I just really like that there are different kinds of toys for him so he doesn't get bored. The rope only lasted a couple of months. He chewed the heck out of it.

Could be dangerous for smaller dogs
Color: Multicolour20
Most of the toys seem to be great,
I have a yorkshire terrier and I noticed that on some of the toys that have small nubs and prices that he can focus on he is chewing off and eating which is not good for his little body so just be careful and pay attention to how they are using the toys so you don't end up at the vet with a problem you didn't expect
