A lifting edge, two handles and a rope lock, printed in matte bio‑PLA and packed into one box with a frog foot on the side. Finger training that goes where you go.
Tendons adapt far slower than muscle, a few percent a week. So the training that works is small, frequent, and loaded exactly as hard as you choose.
Cling is a no‑hang: you lift a weight off the floor with your fingers instead of hanging your body from a board. The load is yours to set, and it works anywhere you can put a weight down. No doorframe, no gym.
Every piece of the kit, from the real print files. The lid slides out on a dovetail, the coupler lets go of the handles, and the rope hardware floats free. Drag to turn it.
Lifting edge first. Then throw the handles over a bar or branch, pinch the block, pull from the couch, or warm up at the crag before the first move.





Every piece is printed from plant‑based PLA made from corn and sugarcane, with a matte finish that holds chalk and doesn't go glassy in the hand.
The frog foot on the box and the handles isn't drawn. It's the outline of the pocket in the bottom of the product, pressed a millimetre into the plastic.
Block, two handles, coupler, rope with lock, donuts and aglets, and the protocol card. Printed and assembled by climbers.
Orders aren't open yet. Series 01 is being printed and tested now.
Cling is a training tool, not climbing protection or PPE. Never use it for fall arrest or to support a person's weight in a life‑safety system. Build load gradually and stop if anything hurts.
