The Shark underground kit foundation box is installed beneath the gate at the foot of the hinge pillar. Refer to diagrams. The minimum distance between the vertical centre line of the hinges and the inner face of the pillar is 65mm. There must also be at least 65 mm between the lid of the foundation box and the bottom of the gate.
Remember if fitting underground drivers to wooden gates, it will be necessary to clad the gate bottom edge with metal to spread the load and to give something to attach the motor shoe. If you don't, the push-pull from the high torque will eventually split the wood.
When fitting Shark underground motors you will need a minimum of 65mm from your gate hinge point to the post. Though soak-aways may be adequate, we recommend that you drain the motor case to lower lying land where possible. All underground motors will operate underwater when new, but if left submerged, it is likely that water will eventually enter the motor and / or cable insulation will become porous. It is better to correctly drain the foundation cases from day one to protect your investment! Some additional fabrication/welding may be necessary to connect the drive shoe to your gates.
Only a single gate? Not sure if you need a right-hand kit or left-hand kit? Don't worry - the Shark kit is ambidextrous!
