Drop forged from aircraft quality 7075-T6 aluminum alloy, the Air Traffic Controller is the ultimate belay/rappel device. It’s light, easy to operate, and won’t lock up unexpectedly. Best of all, when used correctly, the ATC won’t kink your cord. The complex geometry of the ATC allows it to feed rope smoothly yet hold your partner’s screamers with ease. As a rappel tool the ATC provides a silky smooth ride and its extensive surface area dissipates heat.
