An 11mm static rope bridge for swapping out a worn saddle bridge.
This 11mm replacement rope bridge is made from KMIII Max static kernmantle rope in black and yellow. Static rope keeps stretch low, so the bridge stays a consistent length as it slides on your ring or carabiner all day.
The bridge is the part of your saddle that sees the most friction. Your center ring or carabiner slides on it every time you shift sides, and it carries your weight the whole climb. A tight-weave static kernmantle like KMIII Max resists that abrasion and does not stretch much, so the bridge length you set up on the ground is the length you have in the tree. Bridges see a lot of side-to-side travel on a pruning climb, and a firm static rope holds up to that better than a soft, stretchy one.
The high-visibility black and yellow color also makes wear and dirt easier to see during your pre-climb check.
Saddles take different bridge lengths, diameters, and terminations. Confirm that an 11mm bridge of this length and end style is approved by your saddle's maker, then install it exactly as the saddle manual shows. Do not tie your own improvised replacement.
Inspect the bridge before every climb for cuts, glazing, flat spots, contamination, and damaged ends, and retire it on the maker's schedule. Life-support gear must meet the applicable standard and be used per ANSI Z133 and manufacturer instructions by trained climbers. Other saddle parts are listed here.

Yes. It is a low-stretch kernmantle rope, which suits a saddle bridge that should hold its length.
Only if the saddle maker approves it. Diameter affects how rings and hardware fit and run, so check the manual first.
