Series 40 Orbit BB Quin Block with Swivel Shackle

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 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 highly 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
  • Lightweight, yet strong. Toughened, glass fiber reinforced nylon replaces stainless steel straps used in our traditional utility blocks
  • Low friction 2-stage ball bearing system for efficient and effortless trimming
  • Soft attachment, lashing and traditional swivel shackle head options

Nice flexible silicone wire
Size: 14 gauge silicone wire 10ft and 10ft, Color: silicone wire red and black
I purchased to replace the main power cable for an Ender 3 3D printer. The original cables were the same type but had a cheap connector Midway through to allow the power supply to be removed if needed. THOSE NYLON connectors overheated, smelled and turned black. The BNTECHGO 14 Gauge Silicone Wire were a perfect replacement. No more connector and no more heat issues.

This has worked well over the last few years. Used moslty on battery leads for quadcopters. The wire and insulation has held up well, is good quality, solders fine. I have since used other BNTECHGO silicone wire as well, and not been dissapointed.

Great for re-wiring a 12/24v DC PSU for a 3D Printer
Size: 14 gauge silicone wire 10ft and 10ft, Color: silicone wire red and black
I'm familiar with this wire as it was just coming to market as I was fading out of the RC hobby back in ... well the 90's? When I got a roughly cared for and damaged CR-10 for cheap, I decided to remodel it and place the guts and gear under the frame. This wire is thick enough to wire the power plug, MOSFett, and main board with no concern for the 30 A amperage it could draw. It crimped easily, stripped cleanly and is super supple. I paired this with a 7 color pack to re-wire things to arrange plugs where I needed them to be. It's good wire and I may even use some when I dig out my old RC-10 graphite or Bo-Link fiberglass chassis...
