INSTALLING A WALK DOOR FRAME IN SIDE OF BUILDING WITH BASE RAILS

We recommend that you cut out the base rail where walk doors will be located. Cut out a section of base rail wide enough

to fit your pre-hung door frame into the opening (frame width + 3/8”). Measure the height of your pre-hung door frame and

cut a vertical door jamb post 2” shorter than the door frame height. This post will be mounted on top of the base rail and to

the bottom of the door header. (You should have a 2” x 4” x 81 3/4” from which to cut this door jamb post) In your kit you

will have a door header 2” x 4” x 46”, 58” or 70” depending on the on center spacing of your side posts.

Pre assemble these components as shown below and place them in the chosen space between to side posts. The door

frame assembly should be flush with the building frame. The header will be attached to the side posts with BK-10 angle

brackets and the bottom of the vertical door jamb post will be attached to the inside of the base rail with a BK-20 flat

bracket. Make sure the door jamb post is flush and plumb. Use #12 x 3/4” self-drilling screws.
