EV40 User’s Manual
For Hollow-Wall Construction
• Place the unit such that both mounting holes can take advantage of solid structural framing
of the outside wall or a strong wall surface, such as plywood.
• Size 1/4-20 lag screws are recommended for mounting the EV40 to a wooden structure.
Pre-drill approximately sized pilot holes to allow the lag screws 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 the screw head is smaller than the 3/8” 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 a drywall without
a solid backing) it will be necessary to use proper anchoring hardware such as drywall
toggles or molly bolts.
