1. WINDING: RHW or LHW? (See "Winding Chart") |
xx |
METHOD #1:
Furnish spring length
Amount of stretch
Pull of spring in pounds |
EXAMPLE:
25" - 42" - 150# |
| |
xx |
| 2. WIRE SIZE: Measure 10 or 20 coils to nearest 1/16" and refer to "Spring Wire Chart". |
xx |
| |
xx |
|
|
| 3. INSIDE DIAMETER: Measure I.D. to nearest 1/16" and refer to "I.D. Chart". |
xx |
METHOD #2:
Furnish wire size
Inside diameter or outside diameter to nearest 1/32"
Length of spring
Type of ends
Specify if "wound tight" for a "one-piece door" |
EXAMPLE:
.177 - 1 9/32" I.D. - 25" with Double Loops |
| Note: Manufacturers not listed on "I.D. Chart" probably use these I.D.'s: 1 3/4", 2", 2 5/8", 3 3/4", 5 1/4", or 6". |
xx |
| These I.D.'s may often be varified by locating corresponding numbers on the spring fittings. (For example: "175" for 1 3/4" I.D., "200" for 2", "258" or "263" for 2 5/8", etc.) |
xx |
| |

|
|
| 3. LENGTH:Measure overall length of spring, or provide total number of coils in unwound length of spring. |
|
METHOD #3:
Furnish door width & height
Door weight |
EXAMPLE:
8' Wide x 7' High x 150 lbs |
