A stick clip is a long telescoping pole — typically 3 to 5 metres extended — with a holder on the end that grips a quickdraw and the rope. The climber uses it to clip the first (or first few) bolts of a sport route from the ground, before they start climbing. This eliminates the most dangerous moment in lead climbing: the section between leaving the ground and clipping the first bolt, when a fall hits the deck.
Stick clips are universal at sport crags with bolted routes. Many crags have heavily-used "first bolt" sections where the rock has eroded enough to make the unprotected start sketchy. Even at moderate routes, climbers stick-clip the first bolt as a basic safety practice. The pole stays at the base of the route during the climb, available for clipping back at the end of the day.
Commercial stick clips (Beta Stick, Trango Squid Stick) range from 60 to 150 USD. Climbers can also rig DIY versions with painter's poles and small clips. The technique requires practice — the pole is unwieldy, the rope can twist, and getting the gate of the carabiner to snap shut around the bolt takes patience. Once mastered, stick clipping becomes second nature.
