Marlow Maverick 11.5mm Climbing Rope

The Marlow Maverick climbing rope is an 11.5mm arborist line that sits at the slimmer end of the typical range. It suits climbers who want a lighter line for long days while still running the hitches and devices most crews already use.

A slimmer arborist line

At 11.5mm the Maverick is slightly thinner than the 11.7 to 11.8mm lines many climbers know. That saves a little weight in the bag and on your saddle, and a slimmer rope feeds a bit more freely through a hitch or device. The trade-off is that you may need a thinner hitch cord, or a few more wraps, for the same grab.

Marlow builds its arborist ropes for both moving rope and stationary rope work. Use it doubled with a friction hitch, or as a single line on a device that lists 11.5mm rope as compatible.

Maverick is also a sensible line for climbers who want to try a slightly thinner rope without changing their whole kit. Most of the hardware you already own will still work with it.

Setup and inspection

Test any new rope and hitch pairing near the ground first. Check the hitch cord diameter, the device's rope range and how the system behaves when the rope is wet or dirty, since all of these change friction.

Climbing line is life-support equipment. Use it only within the manufacturer's instructions and ANSI Z133, inspect it before every climb, retire it when the cover is cut or glazed or the core feels damaged, and get proper training before you trust it. Compare the Maverick with other 24-strand climbing rope in our range.
