Factor 55 Synthetic Rope SpoolFactor 55 Synthetic Rope Spool There is a common belief that a synthetic rope eye termination should possess a diameter D d ratio in the 6 8 range. Most synthetic winch ropes come with metal thimbles providing this ratio when new. The trouble is that the metal thimbles eventually yield and collapse onto the retaining pin, thus reducing the D d ratio considerably. Is this so bad? What happens to synthetic rope strength when the D d ratio is reduced?

Factor 55 Synthetic Rope Spool

 

There is a common belief that a synthetic rope eye termination should possess a diameter D/d ratio in the 6-8 range. Most synthetic winch ropes come with metal thimbles providing this ratio when new. The trouble is that the metal thimbles eventually yield and collapse onto the retaining pin, thus reducing the D/d ratio considerably.

Is this so bad? What happens to synthetic rope strength when the D/d ratio is reduced?

Luckily for us off roaders, many technical papers have been written on this by rope manufacturers and cordage experts and corresponding tests have been completed. Even when a single leg rope eye is pulled against a D/d of 1 (3/8 rope eye pulled against a 3/8 pin), the rope still retains almost all of its original strength.

Why is this?
It’s because you have the load of the pin being carried by two legs of the rope, similar to basket loading a synthetic sling. In fact, the testing standard for pull testing synthetic rope single legs is to use a shear pin in the (1.5 – 2) X d.

So what’s the bottom line, and what does this mean to us off roaders?

It means that if your rope retaining pin is smooth, and at least as big as the rope diameter or greater, you can run a soft thimble-less eye on the end of your rope and lose little to no breaking strength. We just released rope spools for synthetic winch rope with a D/d ratio of 2.6 for those who would like to run soft eyes on the Factor 55 products.

Gorgeous face
Color: Black Bracelet, Black Dial
This watch has a gorgeous face and dial. The diamond accents give it a touch of excellence. I did buy the men's version and it does have a bigger face than I expected. It is smaller than my Michael Kors stainless one.
