Views:21     Author:Site Editor     Publish Time: 2018-04-19      Origin:Site

When it comes to doors, hinges is very important. Their style and functionality have a huge effect on the performance of your doors. The good news is that a wide range of hinge options are available, so there's an excellent chance there's a hinge out there that's right for your application.



SELECT THE PROPER WEIGHT AND BEARING STRUCTURE

Hinges are placed into three groups because of the various door sizes and weights:


Standard Weight –– Ball Bearing

Example –– DDSS001, 41/2”x 41/2” (114.3 x 114.3 mm), US32D

2BB Door Hinge-D&D Hardware


Heavy Duty- Ball Bearing

Example ––DDSS002, 5”x 5”(127 x 127 mm), US32D

4BB Door Hinge-D&D Hardware


Standard Weight –– Plain Bearing

Example ––DDSS004, 41/2”x 4”(114 x 102 mm), US32D

Plain Joint Hinge-D&D Hardware



There are two factors that determine the weight and structure of the hinge: weight of the door and frequency of use. It is advisable to include the approximate weight of additional hardware that will be installed on the door.


THICKNESS OF DOOR

WIDTH OF DOOR

HEIGHT OF HINGE

13/18” (35 mm) Door

To 32” (813mm )

31/2” (89 mm)

13/8” (35 mm) Door

32” to 36” (813 to 914 mm)

4” (102 mm)

13/4” (45 mm) Door

To 36” (914 mm)

41/2” (114 mm)

13/4” (45 mm) Door

36” to 48” (914 to 1219 mm)

5” (127 mm)

13/4” (45 mm) Door

Over 48” (1219 mm)

6” (152 mm)

2'', 21/4” & 21/2” Door (51, 57 & 64 mm)

To 42” (1067 mm)

5” Heavy Weight(127 mm)

 2'', 21/4” & 21/2”Door (51, 57 & 64 mm)

Over 42” (1067 mm)

6” Heavy Weight(152 mm)





There are three dimensions to know in order to determine the minimum width of the hinge: door thickness, backset and clearance required.


1.When figuring the calculations for a wood door and wood frame, the door is flush with the casing or face of the frame. When figuring the calculations for a wood or metal door with a hollow metal frame, the door is inset approximately 1/8” (3.2 mm).


2.For doors up to 2 1/4” (57 mm) thick, the hinge is set back 1/4” (6.4mm) from the back face of the door.

3.For doors over 21/4” (57 mm) thick, the hinge is set back  3/8”  (9.5 mm) from the back face of the door.


Once these dimensions are known, the formula can then be applied. Take the door thickness, minus the backset, times two, plus the clearance required. If the hinge size is not standard, then go to the next larger hinge width. If the width of the hinge is greater than the height of the hinge (example: 41/2” x 6” (114 x 152 mm) this is referred to as a Wide Throw Hinge. This would apply only to full mortise hinges.
