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.
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.
Ideal for creating simple vang and mainsheet systems up to 4:1 on boats to 12m (40ft)

Size Does Matter
Product: Air Intake Filter
Brand: EPAuto
Positives: Super affordable and compact. Easy to remove and install, just loosen 4 screws and that’s it. Made with quality and durable material. The filter provides ideal airflow for the engine to function properly.
Negatives: None.
Overall Impression: I needed a replacement filter for my wife’s car and I didn’t want to spend a small fortune. This item was practically a steal at the list price. No need to spend more money, all the quality and longevity can be had with this filter. My wife drives her car almost every day and that means it gets a pretty good amount of use and lasts about 12 months until I decide to change them again. I would definitely recommend this product to others looking for a similar product.

Looks as good as the genuine one.
This looks like a quality product, great for the price. It looked identical to the genuine Honda part but was $20 cheaper than the Honda one.
