Series 45 Core Block™ - Single - Swivel Shackle Head

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 optimisation and the cut-away design minimises 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, minimising rope wear.

Features:

  • High dynamic and static load capacity
  • Efficient 2-stage bearing system
  • Ball bearings to counteract side thrust loads
  • Class leading performance and sleek, contemporary styling

Ooo that smell.
Scent: Berry Bubbly, Size: 20 Fl Oz (Pack of 1)
If you’re searching for a body wash that will transform your shower routine, look no further! I recently experienced the most delightful shower using this incredible body wash, and I can’t stop raving about it. The moment I lathered up, I was welcomed by the irresistible scent of strawberry cream—it felt like a treat for my senses! Not only does this body wash smell heavenly, but it also excels in moisturizing. I was pleasantly surprised to find that I didn’t need to use as much product to achieve that perfect lather. It cleanses beautifully while leaving my skin feeling soft and hydrated—what more could you ask for? I've always been a loyal Olay user, but this body wash takes the experience to an entirely new level. I know it might sound unusual to be this excited over a body wash, but trust me, this one is a game changer. You absolutely have to try it for yourself! I highly recommend this product, but don’t wait too long—rumor has it that it might only be available for a limited time. I’m definitely planning to stock up! While I usually don’t share videos, I just had to spread the word about this amazing find. Don’t miss out on the chance to elevate your shower experience!today.

Smells Good, Softens Skin
Scent: Berry Bubbly, Size: 20 Fl Oz (Pack of 1)
It smells so good. The pump works just like it should. I haven’t had any issues with getting the soap out. I can tell a difference in my skin. It feels softer and looks good. It seems like it’s going to last for a while, too.

Great lather, great scent, great body wash!
Scent: Raspberry, Size: 20 Fl Oz (Pack of 1)
I love trying new body washes. I tend to stay away from Olay because I've always heard Dove is better... I'm a convert now because this OLAY is way better than most of the body washes I've tried recently. With most soaps I use, it takes so much product to get it to lather. Not this soap! I used 2 pumps for my whole shower and it was still lathering!! The scent is strong in the best way! I can actually smell it on my skin hours after my shower!! I felt super clean post shower. No residue or dry skin. Just the right amount of moisture left on my skin. I'm going to try the other scents now!
