Series 40 Orbit RT Triple Block with Becket, Cleat & Swivel

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 adjustable for setting 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.

  • Class-leading dynamic and static load ratings

DO NOT BUY! DO NOT BUY! DO NOT BUY!
Color: Black, Color: Black
Absolute garbage chair. Only had for six month and the mesh on the seat has already come apart after using it for my home office. Chair was squaking after only three months and now I can't even sit in it cause it sags. Can't even get my money back for this cheap garbage.

Just What I Needed for My Home Office
Color: Black
I’ve been very happy with this office chair. It was straightforward to assemble, feels sturdy, and offers excellent support for long hours at my desk. The adjustable lumbar support, armrests, and headrest make it easy to customize for a comfortable fit, and the mesh design helps keep the chair breathable throughout the day. Overall, this chair is comfortable, ergonomic, and a great value for a home office setup.

OK for basic Office chair
Color: Black
Positives:Comfortable chair, decent lumbar support. Negatives: no height adjustment for seat or tilt. Handles spin to sides with the slightest touch. Will try to figure out how to securehandles in place. Period good entry level office chair, should have ordered more of an upgraded chair.
