Series 40 Orbit Ball Bearing Exit Block

The Series 40 ball-bearing Orbit Blocks™ provides the perfect balance of strength, performance, and reliability. They offer class-leading dynamic and static load ratings, the highest available in this size of performance blocks. Lightweight and strong toughened glass fiber reinforced nylon cheeks replace stainless steel straps used in traditional utility blocks - the perfect balance of performance and reliability.

As well as traditional single swivel blocks, the range also includes single and double sheave lashing or soft attachment options through to multiple sheave blocks including those with quad and quin sheaves. The range is extremely versatile allowing a multitude of possible systems right up to a 12:1 purchase mainsheet system for off-the-beach performance catamarans.

Series 40 Orbit Blocks™ are fitted with our carbon-reinforced C-Cleat™ for secure rope holding with low entry and exit efforts, and fairleads for fast action from any angle. Cleat arms are made from stainless steel and are adjustable for setting to your preferred cleating angle.

Ball Bearing versions incorporate our 2-stage bearing system using ball bearings to minimize friction and a secondary full-contact bearing to maintain low friction across the full working load range.

High Load versions are designed specifically for any application where high dynamic or static loads are expected. They feature a high-strength grade 2205 stainless steel sheave & hub together with a triple bearing race to maintain low friction at very high loads.

Smooth and ergo nice mouse.
Size: 1 Pack, Style: USB Receiver, Color: Swift Grey
I needed this little thing quickly and got it within 2 hours of ordering. It was only an extra five bucks to get it now. Would have burned more than that in fuel. Works exactly as I would have expected. Perfect.

This is a dandy little item. Easy to use straight out of the box, No fancy bells and whistles.but why should a mouse try to replicate commands that are on the laptop?

Simple, Reliable, and Works Great
Size: 1 Pack, Style: USB Receiver, Color: Swift Grey
The Logitech M185 has been exactly what I needed for everyday computer use. Setup took less than a minute—just plug in the tiny USB receiver and it was ready to go. The mouse responds smoothly, tracks accurately, and feels comfortable in my hand even after several hours of use. What I appreciate most is the reliability. The wireless connection has been stable with no noticeable lag or dropouts, and the battery life has been excellent. For browsing, office work, and general daily tasks, this mouse delivers solid performance at a very reasonable price. I'm extremely happy with it.
