Install the Second Gate
First check plumb and level. Use regular wood shims to raise the gate into the correct position. At this point, install the brackets in the same fashion as for the first gate -- keeping in mind that the gate cannot be moved from its position while shimmed. Once the last screw is secured, the shims can be removed. To finish, install the latch to catch the gate. First, mark the location of the latch. Drill small holes, then attach to the gate frame with a couple of screws.
