Petzl Micrograb Rope Grab Lanyard Adjuster

The Petzl Micrograb is a compact Petzl rope grab that turns a length of arborist rope into an adjustable work-positioning lanyard. It grips the rope with a cam and releases with a simple pull, so you can take up or let out slack on the stem.

Building a lanyard around it

The Micrograb lets you choose your own lanyard length and rope. Many climbers run it on a length of 11 to 13 mm class arborist line with a sewn eye, which keeps the whole lanyard lighter than a wire core flipline. Check Petzl's notice for the exact compatible ropes before you buy rope for it.

If you would rather buy a complete kit, see the Micrograb lanyard add-on kit.

A rope lanyard built around the Micrograb is also gentler on bark than wire core, which matters on pruning jobs where you are choking limbs and repositioning often. It slides around the stem easily and coils up neatly on a saddle loop.

Inspection

Look for wear on the cam, a weak return spring and cracks or deformation on the body. Rope wear behind the cam shows up first, so check the lanyard rope too. A rope lanyard is not cut resistant, so keep it away from the chainsaw or pair it with a wire core flipline when cutting. Life-support gear has to meet the applicable standard and the manufacturer's instructions, get inspected before every climb, and be used only by trained climbers.

Keep the cam clean. Sap, sand and sawdust packed into the teeth reduce grip, so brush it out at the end of the day and let it dry before storing it in your bag.
