KONG Indy Evo Plus Descender

The KONG Indy Evo Plus descender is a self-braking device for controlled descents on a single rope. Tree workers and rope access crews use this type of descender for rescue kits, access lines and stationary-rope work where a handled descender makes sense.

Where it fits for tree work

Most climbing arborists use a dedicated SRS device, but a handled self-braking descender has a place in aerial rescue kits, for accessing a tree on a fixed line, and on crews that also do rope access work. The handle lets you control speed, and the device is designed to hold when you let go.

If you are thinking of adding a descender like this to your kit, start by working out what role it will play: rescue, access or regular descent. Each role sets different needs for rope type, backup and anchor, and those choices shape the rest of your system. Talk it through with an experienced climber or trainer first.

Check the rope diameter range and approved rope types in KONG's instructions before setting it up. See our ascent and descent gear for arborist-specific devices.

Training and inspection

Descenders behave differently on different ropes, wet or dry. Practice close to the ground first and always use a backup or stopper knot as the manufacturer directs.

Treat it as life-support gear: follow the manufacturer's instructions, check it before every climb, and retire it after a hard fall, a drop onto a hard surface, or any damage you can't explain. Use it within an ANSI Z133 program and only after proper training.
