Models 936, 1456, 2906 and 6506 were designed as economic options for raising and lowering curtains on projects where lift speed is not critical. These machines are not equipped with friction brakes and may drift after the stop command is issued. A fairly high reduction in the gear unit helps minimize this drifting. Stop, Start and Reverse action is provided with a reversing motor and three-position maintained toggle control switch. Integral rotary limit switches are provided the for "Full Raise" and "Full Lower" positions.


  • Rotary Limit Switches for full open and full closed positions.
  • Full Voltage Control (motor voltage and amperage runs through the remote control switch)
  • One (1) toggle type remote control station (only one may be used with this series)
  • Flat (un-grooved) Spool 8"L x 4"D
  • Channel Steel Base
  • Connects to 120 volt power supply
  • ETL Listing on the entire machine, not just the control box
  • Approximate shipping weight 165 pounds
