Alternate Installations
The rear mount installation is an excellent way to conceal the chain or opera- tor. The operator is placed in the extreme rear of the gate as shown and the chain never goes across the driveway. The chain only goes from the gate operator to a post or wall beside the driveway. Place shortest edge of the operator 3" from the rear end of the gate and place the long edge of the operator
The chain will form a continuous loop, going around the drive sprocket on the operator, and around the idler sprocket on the post or wall. Only one gate bracket is required on the rear edge of the gate where both ends of the chain come together and attach to the bracket. To prepare the SL920 for a rear mount installation, remove one or both idler sprockets from the operator. Neither idler sprocket will be needed on the gate operator. For the idler sprocket, an ES130 End Sprocket Assembly with chain guard may be used. Alternately, an idler sprocket that was removed from the gate operator may be used. It is recommended that a cover be placed over the idler sprocket in this case for safety.
