Installation of the Closed Position Stops
The GTO/PRO® 4000/4200 Gate Operators firmly hold the gates in the closed position using
positive stops. The positive stops help stabilize the gate leaves in the closed position. To further
enhance stability and security, we strongly recommended using an optional GTO/PRO®
Automatic Gate Lock (see Accessory Catalog) with your dual gates.
IMPORTANT:
You need to
determine which side of the
driveway you will mount the
control box. From this point on
the gate and gate operator on the
same side as the control box will
be referred to as the MASTER
gate and gate operator. The gate
and gate operator on the opposite
side of the driveway from the
control box will be referred to as
the SLAVE gate and gate
operator.

Step 1
Detach the gate operators from the gates and move the
gates to their closed position (Illustration A). Using
appropriate hardware for your type of gate (U-bolts for
tube or chain link; screw or bolts for wood or metal)
attach the closed position stop plate (horizontally) about
mid height on the MASTER gate frame. Do not tighten it
completely at this time. Slide the stop plate toward the
frame of the SLAVE gate leaf until they touch
(Illustration B). Once you have moved the stop plate to
the correct position, tighten its hardware completely.
NOTE:
The optional ground stop post is used to provide a secure point for the SLAVE gate to close
against. If you will be using the GTO/PRO Horizontal Gate Lock accessory with your gate operator
system, the closed position ground stop is REQUIRED, as shown in Steps 2 and 3 on the next page.
