Q: What exactly
is a "Prehung" door?
A: A prehung door
consist of the following components:
-
the door
-
head jamb
-
hinge jamb
-
strike jamb
Our prehung
Redi-Built doors start by using only high production precision door
manufacturing machinery. The door, hinge jamb and strike jamb are all
machined simultaneously in one cycle. All hinge screws are predrilled
and the hinges are applied to the door and hinge jamb. The striker
jamb is routed for face place and striker pocket. Once machining is
completed the door and jambs travel onto the automatic assembler
where the header jamb is positioned and all is nailed together. Now
the completed unit is packaged and ready for delivery for immediate installation.

Q: Are
Redi-Built doors available unassembled?
A: Yes, the door
and the components are factory machined then shipped to the job site.
This is known as a KD-Built (knock-down) unit.
All double doors
are shipped (knock down) |

Q: What is the
rough size opening needed for a prehung door?
A: For single door
from 1/4 thru to 3/0 x 6/8, add 2" in width and 2-1/2" in
height to the nominal size of the door. For example a 30" x
80" door will require a 32" x 82-1/2" RSO. |

Q: What is the backset?
A: The distance
from the high side of the beveled door edge to the center of the lock
bore is defined as the backset. All of our Redi-Built doors are
machined to 2-3/4" backset, this is the most common size used in
residential applications. |

Q: What depth
of jambs are available?
A: For all
Redi-Built assembled units we provide jambs to fit the standard 2x4
wall with 1/2" drywall on 2 sides. Typically a size of 4-5/8"
We provide our
KD-Built for all other off standard jamb depths of 2-1/2 up to
12" in depth

Q: How I
determine if a door is right hand or a left hand swing?
A: All doors are
denoted by the direction of their swing or their hand. There are
several different terms and ways to describe the swing of a door. The
system we use is the most straight forward and easiest to understand.
All you have to
remember is you must always face the door as it
swings away from you then note which
side is the hinge jamb on.
