The CO2 powered gun shoots a foam dart with a line attached to it up to 200ft. Stop climbing your ladder and moving it every ten feet to pull your wire across a t-bar ceiling. Pull your wire the entire distance in one shot with the Laserline! Tired of wiggling through a crawl space just to drag your wire to the other end? Fire the Laserline, attach your wire, then walk around and pull it across while standing. It’s that easy!
