Metolius Nano Rings - Portable Wooden Finger Training Blocks

Metolius Nano Rings are compact wooden finger training blocks you can hang anywhere. Each block weighs 220g and measures 135 × 80 × 40 mm, so they disappear into a pack for warm-ups at the crag, sessions at home or keeping your fingers honest while travelling.

Each block carries four edge depths, 10, 15, 20 and 25mm, plus a 40mm finger jug and a full-hand jug, so you can progress from comfortable hangs to serious edge work on the same tool. Use them as a pair or individually for hangs, pulls or suspension exercises, all bodyweight. They're made from FSC-certified wood, and setup takes seconds.
