1. From inside the attic locate the area between the soffit
joists where you will be installing the soffit vents. Find the
center and then drill a hole to mark it.
2. Make a cardboard template of the soffit vent rough
opening. Cut a hole in the center.
• 14.5" x 5.5" for SV145
• 22.5" x 3.25" for SV223.
3. On the outside of your home, snap a chalkline to indicate
the center of the soffit area. Center the template over each
hole that you made in Step 1. Trace around the template. Cut
out the template outline with a jigsaw or reciprocating saw.
4. Install the vent by inserting it into the opening. Nail into
place with galvanized nails.
Gibraltar Soffit Vents are reversible for new stucco/plaster construction or for surface mount (wood siding soffits).
CAUTION! Working above grade is inherently dangerous, be sure that proper fall protection measures
are in place. When working with power tools, gloves and eye protection are absolutely required.
These installation guidelines are for use with typical or standard applications. It is always recommended to seek advice from a licensed professional,
and to check with your local building inspector or building permit office for approvals and possible variations that may apply.
