Door Measuring
Step 1
FOR EXAMPLE:
If your framed opening is 7’6″ wide and 8’0″ high, you would order a 7’6″W x 8’0″H (width first, height second) door. A = Width B = Height
Step 2
Measure the mounting surface areas. NOTE: All mounting surfaces must be flush.
977 Door | 977 |
|---|---|
BRACKETS C = Width D = Height | 7.5″ and 4.5″ 13″ |
GUIDES E= Width | 3″ (5″ masonry jambs) |
Step 3
Measure the door clearance. NOTE: Insulated doors require an additional 1″ of back room and head room.
977 Door | 977 | 977WL |
|---|---|---|
F = Back Room
G = Head Room H = Side Room | 20″ 22″ 7.5” and 4.5″ | 21″ 23″ 7.5″ and 4.5” |
Step 4
Choose Model 944, 944WL, 977, 977WL, 988, or 988WL from the Door Model Selection Chart. If you are unsure of the best choice for your particular application, consider how your door will be used. The Model 944 is ideal for residential and light-duty needs. Model 988 offers the largest door dimensions. The “WL” models may be needed when building codes require a specific PSF rating.
Step 5
Once you have completed the four preliminary steps for determining your needs, you are ready to order your door.
