Series 60 Core Block - Single - Becket

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.

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.

Flat Plug = Game Changer
Size: 6 Ft(2 prong plug), Color: Black
This is exactly what I needed to clean up my space. The flat plug sits flush against the wall, the long cord gives flexibility, and having multiple outlets + USB ports keeps everything in one place without the mess. It’s a 3 to 2 plug for homes that the electrical hasn’t been updated to 3 prong plugs. It feels solid, not cheap, and the surge protection adds that extra peace of mind. Perfect for a clean, organized setup that actually works.

Useable and pleasant looking
Size: 6 Ft, Color: Black
There's probably not a lot you can say about power strips because they all just do what they're supposed to do. However I needed something that would give me more power Outlets in the small bathroom sink counter space than I had. I tried several of the ones that I had but they either turned out too bulky, thick cords or just too intrusive for what I needed. That's when I came across this little gem. It comes with six Outlets, three USB inserts, and a smaller less thick power cord, and the end has a 30 degree flat angle so that it lays flat against the wall when plugged in instead of sticking straight out like most cords. Most importantly to me was it fit snuggly behind the sink faucet and tightly against the wall. All and all it made the entire application look as built in as possible. I know this seems as if a lot to say about a simple power strip but I've seem other bathroom counter sink tops cluttered with all sorts of electrical devices vying for their own plug in space and I don't need to tell you what that looks like. This is just a simple little power strip that was able to turn a messy looking counter top into a lot less intrusive looking mess.
