The different parts of work required to complete a door frame may be estimated as follows :

Making frame ..........

$ 0.90

Setting frame in building ..........

.25

Casing frame ..........

.44

Band molding frame ..........

.24

Fitting and hanging door ..........

.36

Putting on mortice lock ..........

.25

Cutting in thresholds ..........

.15

Cutting in steps ..........

.12

Total ..........................................

...$2.71

Thus it is worth $2.71 per frame to make and finish common door frames complete in a building. By looking over the above estimate it will be seen that there is a great deal of work about a door frame besides fitting and hanging the door and putting on the lock - hence many are apt to estimate too low. To fit, hang and put a lock on a common door, using one pair of loose pin butts and a common mortice lock, is worth 60 cents. The average day's work is about six doors per day. If the doors are large and require three butts each, it is worth 75 cents per door. Front doors having complicated locks with night keys, etc, are worth $ 1.50 to $2 per door.
