NT Audio manufactures five types of leader: From frame-countdown leader for the initial thread-up of reels, platters and interlocks, to leader for use between trailers and intermissions. Our leader is made from high strength polyester.
Type A
A modified academy countdown leader used for the initial thread - up of reels, platters and interlocks. It has footage numbers printed on clear leader, and the soundtrack is marked for easy threading. Type A is available in six lengths: 18', 25', 35', 50', 70' and 100' rolls.
Type C
Used for intermissions, thread-up and interlock applications with the projector dowser closed. This is a clear leader with blue sound track identification and solid frame lines. Type C is available in six lengths: 25', 35', 50', 100', 500' and 1000' rolls.
Type D
Serves the same purpose as the C leader. The only difference is that this is a blue leader with sound track identification and clear frame lines. Type D is available in three lengths: 50', 100' and 1000' rolls.
Type B
