Dyneema rigging fittings?

The only two brands I can find regarding dyneema rigging, is Colligo and Blue wave. Are there any other ones I have missed?

Seems there has been a lot of talk about how big radius dyneema needs to not be downgraded, but not really any answers. Colligo seem to have 5:1 radius and Blue wave's looks a lot smaller with their stainless fittings.

How about skip all those fancy fittings and splice directly to a turnbuckle's clevis pin? Or any other DIY solutions?

I was thinking going with a DM20, either 8 or 10mm.
Today the rigging is 1x19, 1/4" or if it was 9/32...

At the least I'd use wire rope thimbles, the ones that are one continuous piece. Available on the internet at fairly good prices. Bending the line around the pin of a turnbuckle without a thimble seems to be way too tight a radius.

I've used these ones in the past, albeit only on small boats (< 24 ft)



They are of a closed design and in cross-section are oval shaped, which from what I am led to believe is required for dyneema.



Closed stainless steel rope thimble


Very inexpensive when compared to Colligo, but then again what price would you place on knowing your mast is secure.

Actually, the open ones are for wire rope. The open ends can't cut wire rope.



The closed ones are called sailmaker's thimbles. There are also tube thimbles.

Re: Dyneema rigging fittings?

The bend radius was a huge issue for SK90 Dyneema, which everyone has phased out since SK99 came out. Apparently both SK78 and SK99 can take a tighter radius than 90 could. I'd still not just splice to a pin, but a thimble that will fit the line's diameter should be a large enough bend radius. Unless someone sells you their last spool of 90 cheap.
