Series 40 Ball Bearing All Purpose Exit Block Narrow

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.

The best toys for dogs I could ever find
Size: X Large
I have bull terriers. They chew wood for fun... But this brand in the appropiate size and in any shape has been the best thing for them! They last for a very long time (they have not even dented them and they've had one (another shape) for the last two years. Now I bought these bones so that they can play together, each graving one side of it. They have so much fun! They are worth every penny.

Best chew toy
Size: Medium (Pack of 1)
Kong toys are the best. They hold up through the heavy chewing stage. Definitely recommend if you have a heavy chewer.

Not for aggressive chewers
Size: Medium (Pack of 1)
My dog absolutely loved this Kong Goodie Bone at first and was super excited about it. Unfortunately, it didn’t hold up nearly as long as I expected. Within just a few hours she had already torn pieces off of it, and I ended up finding little red rubber pieces all over the house. I wouldn’t recommend this for aggressive chewers at all. It may work better for lighter chewers or dogs that are gentler with toys, but mine destroyed it way too quickly. Disappointing because she really did enjoy it while it lasted.
