Description
Description
Required on gear-reduced drawbar or slide door operators to slow the door speed down from 1 ft./sec. to 0.6 ft./sec. The speed reduction is achieved within secondary reduction of the door operator. The door operator powerhead is mounted in the normal manner.
Must be factory installed.
NOTE: The slower door speed allows a proportional increase in door size for the same HP model. With this modification, a GT50 will operate the same size door as a GT75 will at normal speed.
