Installation Instructions

STEP 8: ASSEMBLE SIDE WALK DOOR FRAME AND OPTIONAL WINDOW
FRAME
The Door Frame consists of a Header Tube 2” x 3” x 45 3/4” long (for 4’ OC) or 57 3/4” long (for 5’ OC) 69 3/4” (for 6’ OC)
and a Door Jamb 2” x 3” x 81 3/4”. These combine with the side post to create a 38” x 81 3/4” rough opening for your
door. Note: If your building is on a slab, the base rail can be cut out at the door opening to prevent a trip hazard.
If you will cut out the base rail use a reciprocating saw with a metal cutting blade. Measure your door frame and cut an
opening in the base rail 1/4” wider than the door frame width. Cut in the section of the base rail away from the anchor
hole location. If you cut out the base rail you will also need to cut the vertical door frame member down from 81 3/4” to
the height of your door frame minus 2”. The vertical should sit on top of the base rail.
Place your pre-hung door into the building frame, set the door header tube on top of the door frame and attach the
header tube to the frame on both sides with angle brackets and screws. Now, measure from the bottom of the door
header to the base rail and cut the 2” x 3” x 81 3/4” door vertical down to fit. Set the vertical in place against the side of
you door frame and attach it to the bottom of the header with an angle bracket at the bottom to the base rail with a flat
bracket on the inside of the building. Remove the door from the opening and install two vertical nailer tubes and one
header nailer tube using #14 x 2” self-drilling concealor screws (black screws with #2 square drive). The vertical nailers
are a 1 1/2” square tube x 81 3/4” long with 5 holes and the header nailer is a 1 1/2” square x 42” tube with 2 holes. You
may have to cut the vertical nailers to fit.
