Important Measurements and Terms
Details Critical to Filling an Order for Door Hardware.
Before trying to fill an order for door hardware, jot down a few details about the door and its hardware.
* Thickness of the door.
* Hand of the door and the locks.
* Width of the door and stiles where push and pull bars and kick plates are required.
* The type of strikes required for cremone bolts, surface bolts and casement fasteners.
* The type of lock front, whether flat beveled or rabbeted.
* The backset of the locks.
* Sizes of the escutcheons, push plates door pulls, etc. (Vertical dimensions first).
* If special strikes are needed, the length of the lip.
* Height of the door where cremone bolts are used.
* Length of casement adjusters, bolts, transom chains, transom lifters, etc.
* Special conditions that require details or drawings.
Determining the Hand of Locks & Doors
The rules for handing were set down in the 1880's, giving the industry an established standard that had been badly needed. There are exceptions to the handing rules for specific cases. However, the following rules will cover the vast majority of situations and prevent confusion when discussing door hardware requirements.
* The hand of a door is determined from the outside.
* The outside of an entrance door is the street side.
* The outside of a room door is the hall side.
* The outside of a closet door is the room side.
* The outside of a communicating door is the side where the butts cannot be seen when the
door is closed.
* The outside of twin doors, either sliding or swinging, is the space between the two doors.
* Standing outside the door, if the butts are on the right it is a right hand door; if on the left it
is a left hand door.
* When standing outside, if the door opens away from you, use a lock with a regular bevel
latch bolt; if it opens towards you, use a lock with a reverse bevel latch bolt.
* Locks labeled "reversible" can be used on doors of either hand. However, if the door is
beveled the hand and bevel of the door must be considered.
* The hand of French doors is taken from the inside when cremone bolts or casement
fasteners are used.
* The inside of a French door is the side to which the cremone bolt is applied.
