6550 Commercial and Industrial

The 6500 Series Operators are designed to operate Vehicular Swing Gates in residential, commercial and industrial applications for both single and bi-parting gates. The Operator swings gates 90 degrees in approximately 12-14 seconds.

The unique design of this Operator allows for easy access to the electronics and mechanical areas of the Operator without ever having to remove the gate arm. The electronic magnetic limits will never wear out or break and they are easily adjusted. The solid steel frame and belt-driven gear box make this operator one of the quietest on the market today.

Product Features




Split Case

Two-piece split steel housing allows easy installation and maintenance.





One of the Quietest

The solid steel frame and belt-driven gearbox make this Operator one of the quietest on the market today.


Steel Frame

Provides strength and durability even in harsh weather environments.

Loop Detectors

Easy plug-in ports for DKS Loop Detectors.

Breakaway Hub

Unique breakaway hub design prevents gear box damage if the gate is struck.

Easy-to-Adjust Electronic Magnetic Limits

Eliminates old-style mechanical switches that can wear out, break, or fail.


Technical Specifications

  • Maximum gate width 25-ft.
  • Maximum gate weight 2000 pounds*.   (*Assumes gate swings level and is in good condition with properly adjusted hardware.   Other external factors may affect the performance of the gate operator.)
  • 115 VAC.   High Voltage Kit allows the operator to be powered from 208, 230, 460 or 575 source voltage. In dual gate applications, only one (1) kit is required (secondary operator DOES NOT require a high voltage kit).
  • Class I, II, III and IV applications.
  • Compliant with UL 325 and 991. ETL Listed.   (Note: To be compliant with UL 325 and industry safety guidelines, additional Type B1 and/or Type B2 entrapment protection devices are required to be installed with this gate operator.   Your professional DKS system installer can provide you with more details on these devices and on current industry safety standards.)
