"5" from jamb rabbet to top edge of barrel |
|
Bottom hinge |
"10" from bottom edge of barrel to finished floor |
|
Third hinge |
centered between top and bottom hinges |

The above is U. S. Standards procedure |
|
|
*Certain western states use as standard 7" from top and 11"
from the bottom |
|
|
|
HOW TO
DETERMINE THE NUMBER OF HINGES PER DOOR
As a general rule you will want to use 1 hinge per every 30"(0.760m)
of door or fraction thereof.
Referring to door height:
|
Doors up to 60" |
2 hinges |
| doors over 60" but not over
90" |
3 hinges |
| doors over 90" but not over 120" |
4 hinges |
|
|
HOW TO
DETERMINE THE HINGE WIDTH
You need: 1. Door thickness 2. Backset
3. Clearance required
Wood Door x Wood Frame: The door would be flush with the casing or face
of the frame.
Wood or Metal Door x Hollow Metal Frame: The door inset would be ¹/8".
Doors up to 2 每¼" Thick: The hinge is set back ¼"
from the back face of
the door.
Doors over 2 每¼" Thick: The hinge is set back ³/8"
from the back
face of the door.
Once these dimensions are known you can apply the
following formula:
Take the door thickness, minus the backset, times two, plus the
clearance required. If the size is not standard move up to the next
larger hinge width.
The first dimension of a full Mortise hinge is the hinge height. The
second dimension is the hinge width when both leaves are in the open
position. It may be necessary to extend the width of the hinge to clear
trim or wall conditions.

CARE IN
MAINTENANCE
If a rust-resistant base is desired. ALL hinges are either zinc plated
or copper plated prior to the final finishing.
Plated finishes are all well lacquered to retard oxidation of the
finish.
For a BHMA specification category, a hinge will meet or exceed BHMA
requirements 每 gauge of metal, hinge size supporting specified door
weight, type of finish. We are under constant testing and evaluation
with both Warnock Hersey and Underwriters Laboratories.
Refinements are included such as special milling of the knuckles on all
bearing hinges for proper seating of the bearing surface.
The streamline design of s five-knuckle and concealed bearing
series, meets the demands of todays architectural standards without
sacrificing quality, strength, serviceability, or price.

HOW
TO SELECT THE PROPER WEIGHT AND BEARING STRUCTURE
There are three groups of hinges:
Standard Weight 每 Plain Bearing
Standard Weight 每 Ball Bearing
Heavy Weight 每 Ball Bearing
To determine the weight and structure of the
hinge you must consider:
Frequency of use
Weight of door
Weight of door hardware
Ball bearing hinges should always be used on doors
where door closers are applied and in all fire rated openings. Heavy
weight ball bearing hinges should be used on heavy doors and high
frequency use doors. |
|
|
HOW
TO SELECT THE PROPER HINGE SIZE
To determine the proper
hinge size consider the following:
1. Door Height 2. Door Weight
3. Door Width
4. Door
Thickness 5. Trim Dimension Required
First find the height of hinge.

NOTE
1: All hinges or pivots, except spring hinges,
shall be of the ball bearing type. Hinges or pivots
employing other antifriction bearing surfaces are
permitted if they meet the test requirements of Standard
for Butts and Hinges (ANSI A156.1). Spring hinges shall
be labeled.
NOTE
2: 4½-in. (114-mm) high, 0.180-in.
(4.57-mm) thick hinges should be used on doors which are
usually wide and heavy or which will receive high
frequency use or unusual stress.
NOTE
3: Some manufacturers may provide fire doors
with hinges of lighter weight which are not ball bearing
when they are part of a listed assembly and meet the
test requirements of ANSI A156.1 and have been tested to
a minimum of 350,000 cycles.
NOTE 4:
Pivot sets made up of components smaller and/or of a
lighter gage than shown in Table 2-8A may be used
provided they meet the requirements of ANSI A 156.4 Door
Controls (Closers), and are in accordance with the
manufacturers＊ labeled service procedures.

APPLICATION
DETERMINES KIND OF HINGE
Use Three Hinges To A Door 每 Use Anti-Friction Bearing
Hinges On Doors Equipped With Closers |
| TO
SELECT THE PROPER HINGE THE FOLLOWING FACTORS SHOULD BE
CONSIDERED |
- The material of the door and frame
determine method of application, i.e. mortised,
surface mounted, half surface mounted, or half
mortised.
- The size, thickness and weight of the
door 每 Wider doors, put more strain on hinges, so
taller hinges should be used. Thicker doors require
wider hinges. Heavy doors require taller, heavier
gauge, narrower hinges.
|
- Clearance of the trim when a door
swings 180∼ effects the width of the hinge.
- The frequency of use and the abuse
the door will be subjected to effect hinge choice ＃
heavy duty ball bearing, average ball bearing or
non-ball bearing hinges. It also effects the need for
additional hardware such as closers, panic devices,
etc.
