How to tie on a bridge

Overhand Knot on a Bight Retrace

First, tie an overhand on a bight so you know how much material you need.

Then untie the knot and tie an overhand knot where your original knot started

Feed the tag around your loop

Now just retrace the knot

Two knots like this in webbing reduces the total length about 30" (I don't make my loops small)

What knot is that? Is it just an overhand or an overhand on a bight? I was just sitting down trying to figure out how to tie a good, safe knot to both ends of the Sit Drag without a lot of twisting.

It becomes an Overhand on a bight after you retrace it. It is a tried and trusted climbing knot used for making anchors around trees

How did you tie the second one without being able to wrap the bight due to the Sit Drag and bridge combo being a full circle?

You tie both loops in place around the SitDrag.
Just follow the pics above. It's so simple that when I finally got it I laughed

But the way... you can do the same thing with a Figure 8

Sweet! After 3 tries, I finally got one to work!!!

The water knot is fine for webbing but you should use a figure8 or a tripple fishermans loop for a rope bridge.

Technically, this is the exact same final knot as an "overhand on a bight" which is rescue rated. He just used a retrace technique to get it done since he didn't have a free tail to loop through for the overhand. I used the overhand on a bight two seasons in a row without any noticeable loss of tails. Although "technically" a slipable knot, I haven't noticed any slippage. Long tails and frequent checks and it should be very safe.

I am NOT a climbing expert. But I have friends that are. General consensus is that yes, a Fig 8 is stronger. But the knot isn't the weak link in this equation.
Your sit drag will pop WAY before my bridge will.

They mainly use the Fig 8 when they know they have enough rope and space to fit the knot and they know it is going to get loaded and they want to be able to easily untie it afterwards.

David Toms has a youtube video of the webbing he called an adjustable bridge. I am using it (water knot) to get the finale length i want for my bridge.

FWIW as this is an old thread, I'm using a buntline finished with a half hitch. There have been some good videos posted on the topic of cinching termination hitches since this thread. Hope this helps anyone who's searching for info tying a fixed bridge on a saddle. JR

Evidently inspection is necessary throughout use; but initially, climbing industry "spec" requires that the length of any tag end of a knot be at least 5x the rope diameter. I.e. a 13mm rope should have a minimum 65mm (2.6") tag end exiting the knot. These lengths also are after fully "dressing" the knots.

Do your own research lol. Don't just take my word for it!

I prefer scaffold knots for bridges on my hunting saddles
