The GTO/PRO 2000 and the GTO/PRO 2200 can be mounted on any size column, but the gate hinge cannot be more than 12" from the mounting surface of the post bracket. The edge of the post bracket must be aligned with the edge of the column face where the hinges are mounted. If these conditions cannot be met, and you do not want to pocket the column, Call GTO"s Service Deptment for Alternative solutions.

In column applications, the rear mount of the operator will be attached directly to the gate bracket without the use of the spacers between the rear mount and the gate bracket, 5 on the top and 5 on the bottom. Align washers, rear mount holes and gate bracket holes, then secure with 1/2" x 3-3/4" bolt and lock nut. When tightening the 1/2" nut, lsave it just loose enought for the arm to swing freely.
