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 use on mainsheet, spinnaker sheet, vang, halyard and backstay applications on boats up to 14m (46ft).
General applications on larger yachts.
Alloy sheave models are available for use with wire.
Materials
Sheave: U.V. stabilized acetal or anodized aluminum (AW models).
Cheek plates: Aluminum alloy
Ball Bearings: High compression strength carbon black acetal.
Post & hub: Grade 316 stainless steel.

A must have to 3rd Gen Tacoma (2016-2023) owners

Got this driver side grab handle for my 2019 Tacoma Access Cab TRD Sport trim. I'm not sure why Toyota didn't made this a standard features on these trucks. Getting in and out was somewhat a chore without this handle. I'm glad someone finally made this driver side grab handle.
Installation was very easy and it even comes with a small plastic pry tool and all the necessary hardware. All the mounting bosses are already on the A-pillar. It fits and the actual handle is very well made and sturdy. It is solid plastic vs some hollow cheaply made. Appearance wise, the plastic, fit/finish, and even the texture of the trim matches the truck's black interior.
Great and and a very well made product and now getting in the truck, you can just grab onto the handle and pull yourself in.
