​​​​RLD Jackshaft Advantages
  • CodeDodger® 315/390 MHz receiver can store up to 255 standard and/or open/close/stop transmitters
  • Soft start and stop reduces stress on the door and operator for improved life
  • Safe-T-Pulse® - Internal cable slack detection eliminates external cable monitoring devices and reverses door travel when cable tension isn’t detected for safety
  • Operator force profile detects irregularities in operation of the door to identify unsafe door operation. The force profile is updated every cycle to account for changes in weather and temperature
  • Precision sealed roller bearings on output shaft for improved power transfer
  • Interlock circuit with pre-installed jumper
  • Output shaft coupler utilizes six set screws with threadlocker to reduce shaft slippage and screw back outs
  • Output shaft coupler can be used on 1” hollow or solid door shafts with 1/4” keyway
  • Optional LED worklight may be toggled via the stop button on Open/Close/Stop control station when the door is inactive
  • Small operator profile of 12” length by 6.9” width allows for use in tight applications. Only requires 2.5” of headroom clearance and 7” of side room clearance to be used
