cy circumstances. Positive latch accepts pad locks. Lintel and hinged door provides access to crawl space and base-
ments.
Material Foundation Access Doors are made from heavy gauge steel with all welded construction and are coated
with corrosion resistant paint, so they can be nish painted to match any structure.
Instructions Identify a location for the door that is clear of utility meters, pipes or lines, and allows at least 6 feet of
depth clearance on the exterior. With the location chosen, choose a foundation access door size and style to suit
your needs.
Measure and mark dimensions for rough door opening on both the exterior and interior. Include any additional
clearances called for in the specications to allow for easy placement and adjustments for plum and level.

the foundation by driving concrete screws into the foundation with your drilled tted with a screwdriver bit. Ensure
the frame is both is plumb and level. Place the door in the frame, check for plumb and level and smooth opening
and closing and attach the door to the wood frame.
