The Kong Prog is a stiffened tubular sling with an end connector that closes automatically. The PROG mechanism stays opened until pushed onto a bolt, at which point the gates close. The gates stay closed when loaded to avoid them accidentally coming undone. The mechanism when paired with the inner bar in the sling creates a useful system for progressing to the next bolt when it's just out of reach to work a route or get past a dangerous section of climb.
