A length of the same threat is tied to the inside end of the wire and secured to the spool. When the end of the wire and threat is reached on the Model 80 series of recorders, both the take-up spool and supply spool will be stopped, and the wire will be prevented from running off the supply spool. It is recommended that the "Run-Sop-Rewind" control lever be moved to Stop as soon as possible after the end of the wire and threat is reached. On the Model 180 series of recorders, the leader will be pulled tight against the automatic stop levers to shut off the power of the entire recorder. A 6-foot length of threat is supplied with each empty spool No. SP-176 and SP-077. This is sufficient for 100 spools, allowing the three foot leaders at each end of the wire.
