FAQ: Rope Logic Replacement Rope Bridge

The rope bridge on your harness is subject to friction, bending and flexing throughout your climbing and work positioning. Chances are that the harness manufacturer recommends retiring your rope bridge every six to nine months, even if it’s not showing any signs of damage or wear. Rather than replacing your entire harness, it’s easy and affordable to simply replace your rope bridge. Here’s some useful information about Rope Logic new replacement rope bridge.

What is the purpose of the rope bridge?  
A rope bridge is a length of rope that is the primary connecting point from a harness to an arborist’s climbing or work positioning system. It offers versatility through being compatible with a wide range of hardware. Replacement rope bridges are used to replace used/worn rope bridges in a climbing harness.


What is the difference between being “compatible” and being “approved” with a harness?
“Compatible” means the rope bridge dimensions match what the manufacturer used with the original harness.

“Approved” means the rope bridge has been tested, certified, and approved by the manufacturer for use with a specific harness.


What harnesses is this rope bridge compatible with?
This rope bridge is compatible with all rope bridge harnesses with anchoring holes <20mm (ID).

What sets this product apart from other products in the industry and why?
This particular rope was specifically engineered and developed for the use in a rope bridge style harness. It contains a Nylon/Dyneema core which provides optimal firmness and roundness of the rope and high carrier count Polyester sheath for extended wear.


How do I determine when to replace my rope bridge?
Read the instruction manual that came with your harness. In most cases, it will recommend replacing your rope bridge within 6-9 months of use, even if the bridge shows no signs of damage. If there is damage, replace your bridge immediately. Damage can include:

      • Nicks and abrasion on the sheath of the bridge
      • Bulging of the sheath or flat spots, especially in the middle of the bridge.
      • Fraying of the sheath or ‘core shots’ where the core can be seen through the sheath.
      • Cut or loose stitches on sewn eyes.

When in doubt, replace the rope bridge.

What is the most common issue and how do I avoid it?
Two double fisherman knots are required at each end to ensure the rope remains anchored between the anchoring holes, inspect both knots to ensure they are firmly secured.

Avoid contact with any sharp objects to prevent cuts to the rope.  

Caution should be used to prevent any sharp edges (such as found on a hand saw or chainsaw) to come in contact with the rope. Extended use of hardware on the bridge could be a catalyst to shorten lifecycle.

Make sure to fully inspect your bridge prior to each climb.


How easy is this product to use?
On a scale of 1 (very easy) to 5 (difficult, takes practice and calibration), this product is a 1. This rope bridge functions and performs like the rope bridge that came on your harness originally.


How do I maintain and store the replacement rope bridge?
Wipe off any excess debris when necessary and store in dry place, away from extreme heat and UV. Avoid storing near sharp objects.
