EVSE mounting for hollow-wall construction
•
Place the unit such that both mounting holes can take advantage of solid structural framing inside of the wall or
a strong wall surface such as plywood.
•
Size ¼" - 20 lag screws are recommended for mounting the EVSE to a wooden structure. Pre-drill appropriately
sized pilot holes to allow the lag screw to grip the wooden structure while preventing the wood from cracking or
splintering while the screw is fastened.
•
The included plastic angle washers can be oriented to allow the lag screws to be fastened at an angle while still
providing a solid flat backing to the screw head.
•
If the screw head is smaller than the ⅜" (1 cm) washer aperture, an additional flat washer will need to be placed
between the plastic angle washer and the head of the lag screw.
•
If either mounting hole does not have a solid mounting structure (such as drywall without a solid backing). It will
be necessary to use proper anchoring hardware, such as drywall toggles or molly bolts.
