Wood Doors

All of our wood doors are prefit and beveled.

We allow for 1/8″ head clearance and 5/8″ sill clearance

making the net door size 3/4″ less than nominal size.

Wood doors are also undersized 3/16″ in width on the

high side. For instance, if you order a 30 x 70 wood door,

actual size would be 35 13/16 x 83 1/4 to the high side of

the bevel.

Our standard hinge backset is 7/32″.

Hollow Metal Doors

All of our hollow metal doors are square

edge. We allow for 1/8″ head clearance and 5/8″

sill clearance making the net door size 3/4″ less than

nominal size. Active hollow metal doors are undersized 1/4″

in width and inactive hollow metal doors are undersized 1/8″

in width.

Our standard hinge backset is 7/32″.
