Creating Mounting Slab
5
1. Determine the height of your concrete pad based upon how high the gate is from the ground and where the
belt can be mounted to the gate. The minimum height from the top of the slab to the belt is 10”.
2. Pour a concrete pad for your opener to bolt to. Levelness of the pad is important. For convenience place a
piece of conduit that runs up the center of the pad and the other end is easily accessible.
3. After the foundation has dried, use 7/16 concrete anchors attach the opener to the base.
NOTE: The gate opener can be placed on the left or right of the driveway. The diagram below is for being
placed on the left side of the driveway (if you are standing on the inside of the property looking out)
Mount Base
* Pad can be larger/closer to gate as long as opener is mounted at correct distance from the gate.
** Dimension can be greater if spacers are used to offset gate brackets from rear face of gate.
Spacers will need to be (Base distance from gate) - 31/8 = Spacer Width.
Concrete Slab Tips: Creating a wood rectangle with no top is a good way to form a slab. After the cement
dries the wood can be knocked away. The slab must be secured to the ground below. Having rebar pass into
the slab works well.
