Yale Prism Climbing Rope, 11.7mm

The Yale Prism Climbing Rope is a climbing line for tree climbing on a hitch or device. Here is how it handles on the job, what to check before you buy, and how to keep it in service.

How it climbs

Prism is an 11.7 mm Yale climbing line. The near half-inch diameter gives a confident grip, works with the hitch cords most climbers already own, and has enough mass to wear well on a rope that gets used hard in removal work.

A 24-strand cover is tightly braided and round, so the rope holds its shape under a hitch, feeds smoothly through pulleys and mechanical devices, and resists flattening over branch unions. Lines like this are used for moving rope (MRS/DdRT) climbing and, where the manufacturer lists the rope as compatible, for stationary rope (SRS) work. Most climbers buy them in hanks with a spliced eye on one end.

Compatibility, inspection and care

Before you buy, check the diameter range of your hitch cord, ascenders and descent device, since compatibility is set by those makers. You can compare it with the other 24-strand climbing ropes we carry.

Climbing rope is life-support equipment. It must meet the applicable standard, ANSI Z133 and the manufacturer's instructions. Inspect it before every climb for cuts, glazing, sheath damage and soft or stiff spots, keep it away from saws, fuel and bar oil, and retire it when in doubt. Get trained before you climb.
