Bulldog Grips for High Modulus Rope

Bulldog grips (aka wire rope clamp) can be used to quickly make an eye around a thimble. Typically used with two or three in a row.

Is there any equivalent for High Modulus rope?

I know the rope can be spliced, but in some circumstances you may need a quick or temporary eye around a thimble, and a device equivalent to a Bulldog Grip could be very useful if it exists.

Nothing beats a splice, nothing around a thimble can be rushed without risk of mechanically damaging by the crimp. Whip it whip it good....

I did exactly that about 4 years ago on one of my anchor bridals and it's still holding tight. I used the Clamptite tool. ClampTite - The Official Website | ClampTite | tools | business opportunity Easy and works very well for almost any clamp situation.

Re: Bulldog grips for High Modulus rope

Keeping in mind the thimble you choose must not introduce any mechanical chafe i'd tend to use this 100% strength Quick Splice you could shrink wrap on top or whip..... Cheers

Re: Bulldog Grips for High Modulus Rope

Thanks for all the suggestions. I'm quite keen to look further into the Yale quick-splice (although I'm not sure whether it only works for their "dielectric" rope) and the ClampTite idea. Thanks again.

Re: Bulldog Grips for High Modulus Rope

There are also splicing nuts: SplicingNut...every line needs a secure loop

Most high modulus rope is easy to 'quick' splice - much easier and faster than standard Dacron double braid. In high modulus single braid you can do that Yale quick splice (or just a simple Chinese finger splice) and in high modulus double braid the core takes all the load so you just peel the cover back and again do one of the quick splices in the core.

There were some tests of 'splices' done with the ClampTite which indicated that they weakened high modulus line significantly by creating a sharp hard spot stress riser where the wire clamp ended.

The splice nuts say specifically in their instructions not to use with high modulus.

A bunt line hitch is a decent knot for high modulus rope. It's what the volvo guys use when they need to do something quickly on deck and don't have the time for a splice. If its spectra single braid you need to put a stitch or two thru the tail to make sure it does not slip under load.

Very valuable feedback, thanks.

That's a no-no. Never apply heat to high-mod rope. Spectra/Dyneema permanently lose strength starting at about 175F.

I would do a knot for quick temporary needs. Splicing single-braid is so easy there is no reason to do a knot unless it's an emergency.
