So why do you need to secure the tres end to the tab of the pulley anyway? Why not just secure it to the biner between the cheek plates like this?

I'm not talking about securing legs of hitches, thats all been done before.
Good photo though, shows set up for right handed climber?

I brought my climbing gear home especially.
Its raining.
I brought all the gear inside and set it up.
Battery flat on camera!
Pub looking like better option!

I'll continue this in the Rant and Rave section under hitchclimber as that is where it should be.

Chris and Mark, what types of ropes would you approve of as replacement bridges for the Treemotion? Polyester only? At least 5000 pounds?

Nick. The manufacturers replacement part is approved!
Please take a look at the flow chart here (in particular the third box):
http://www.treemagineers.com/downloads/flow_chart_def.pdf
Not being awkward, but we know the test results from the rope we are using, therefore we can identify that it is appropriate for the task. Equally, the product retains its' certification if approved replacement parts are used and installed correctly.

Chris, that's what I thought the answer would be. I checked out the flowchart last night and that's what actually spawned the question.
I think you guys should broaden the approved ropes for bridges. Right now you have one rope by one manufacturer. Not only that, it's a company that doesn't sell much in the US. I doubt I could find a store in all of Los Angeles that sells that rope.
Point is- it seems that this is an application for which MANY ropes would fit the criterium. As I can see, they are:
1- Must meet a minimum strength requirement
2- Must be small enough to fit the hole, but not so small that the knotted double overhand knot could fit through the hole
3- Must be abrasion resistant enough to withstand the daily rigors of the work expected of it
4- Must not be slippery enough that it can't hold the double overhand knot
I think that's it. I would hate to have someone come to a competition and not have their saddle approved because they put Sta-Set X as the bridge, but the manufacturer has only approved Ocean Polyester rope, which they couldn't find in time for the comp.
The flow chart is VERY clear. I'm glad you made it. I wish more manufacturers would show that level of dedication to their customers! I do have one question about it, though...
Let's say I want to replace my bridge. I go to the chart and>>
Am I competent to replace it? Yes>>
Is the proposed bridge approved? I don't know>>
Check treemagineers.com>>
At the site...I get confused. It shows a rope there, but it doesn't say, "this is the only rope approved as the bridge." Not only that, but the bridge that shown in all the pictures is NOT the rope that I see on the website....
What's one to do?
Is Ocean Polyester the rope that should be used? If so, which size? Can other ropes do the job? Beeline is of very similar construction- especially the larger diameter. There are many other ropes that would fit the bill, too.
love

I hear what you say, but it's not quite so simple. From a certification and liability point of view, you can not look at the rope used in the bridge as 'a bit of rope'. When the need arises, it is a 'replacement part' that is required.
A replacement part must be labelled and identifiable as a component for a PPE product (CE). The replacement bridge for tM has one knot pre-tied, dressed, set and stitched in place. In this way, the end user has not only the flow chart for reference, but also a finished knot to look at and compare.
If we were to add approved cords for the bridge, we would have to carry out a full set of certification tests for each one. I am sure you can see the expense in that process.
You are correct that the replacement part does not feature on our web site. Its' part number is however given in the User Instructions that accompany each harness. Following this route ordering should be simple, it is not necessary to know the specification or diameter of cord, although that may be of interest to some.
Ocean Polyester is not the rope used in the bridge.
tM dealers will be able to supply replacement bridges in the same way that dealers also supply replacement bridges for BFII, Tree Magic etc.
