Sewn eye Prusik rope for Bridge???

[Wall hanger]

Can tell me why I couldn’t use a sewn eye Prusik rope for a bridge? I didn’t like how bulky the bridge from my kestrel is and was looking at the Prusik knot on my linesman and tree tether rope and it got me thinking why couldn’t I use that for a bridge.
I would think if a Prusik rope is safe on my tree tether why wouldn’t it be safe for a bridge.
The only thing that has me thinking otherwise is I see on the NewTribes webside under the description of there new Prusik it says “caution do not use as a bridge”.

Tubular webbing is rated for a bit over 4000 pounds. That’s as low as I would go. So that is probably 8mm or 9mm.

Whatever you get, check the rating, and make sure you are comfortable with it.

There is a thread floating around somewhere where I saw someone using a 30inch pre sewn prusik cord girth hitched on 1 side and attached with a caribiner on the other I'd imagine that would be o-k, just be sure to do your research on the ratings, not all prusik cords are created equally. I believe it is safe to hang from a prusik on a tether or lineman belt because of the way I the hitch distributes your weight throughout the entire line it essentially doubles the strength of the cord as opposed to being hooked from end to end.

If your main reason is to reduce bulk, why not splice an amsteel bridge?
It's super easy to do, it is lighter, more compact and a whole lot stronger.

I have very limited experience hanging from a prusik cord bridge. Maybe a total of 10 hours. But it seemed to be fine and I know others have done it. I used the Sterling flex 10mm prusik with Viking sewn eyes. It's rated at like 8,000 lbs if I remember right. It was pretty solid and I may go back to it eventually. But for now I am running two 23kn Sterling runners that are 24" long ran through 1 inch tubular webbing to keep them together and attached to my saddle with delta links. I really like it.

I use one of these. Its plenty strong and is very clean. No knots and not bulky. Its dynamic rope but for such a short piece there isnt any stretch. I attach it with a delta link on each side

Do this with the Samson predator rope that you have and get rid of the double figure 8 knot. Put a Rooeman1 and a carabiner on the other side. Then you have an adjustable bridge. Also costs you nothing for a great set up. I actually put the eye on the rope around the saddle loop so you can not remove that side.

YOS (year of safety) ... be careful using hardware to attach your bridge. Make sure the hardware you use cannot be cross loaded. Tethrd just put out a video testing their Amsteel bridge, the carabiner was the weak link, and it was NOT cross loaded. Even at full strength, the carabiner failed before the bridge. Just something to keep in mind.

If you like delta links, shoot for the P11 8B or P11 8BN. I personally like the Petzl Ring Open, it's 70 g and 23 kn in all directions (which prevents cross loading).
