Standard Door size 3' 0" (.91m) x 7' 0" (2.13m)*

Design Options: A comparable CB 3 Knuckle or “F” Line hinge may be substituted. A comparable non-ferrous hinge may also be substituted. A comparable different configuration of hinge may be subsituted.

HINGE HEIGHT – OTHER DOOR SIZES*

Example 1 – 150 Ibs. (68 Kg) door 13⁄4" (44mm) x 3'(.91m) wide x 7' (2.13m) door–Medium frequency application. Select door weight column 126 lbs. (57Kg) to 175 lbs. (79Kg) and select door size column 13⁄4" (44mm) x 3'(.91m) wide x 7' (2.13m). In box where both lines intersect use CB179 4 1⁄2"x 4 1⁄2" (114mm x 114mm) or 4 1⁄2" x 4" (114mm x 102mm)hinge for medium frequency use.

Example 2 – 100 Ibs. (45 Kg) door 13⁄4" (44mm) x 4'(1.22m) wide x 60" (1524mm) hinge spacing and high
frequency application.

Solution: Door width factor 4'(1.22m) = 1.33; Hinge spacing factor 60" (1524mm) = 1.17

Multiply: Door weight x door width factor x hinge spacing factor.; 100 Ibs. (45 Kg) x 1.33 x 1.17 = 156 Ibs. (70 Kg).

Check: Door weight column 126 Ibs. (57 Kg) to 175 Ibs. (79 Kg) and 13⁄4"(44mm) door side column. Where they intersect use CB168 4 1⁄2" x 4 1⁄2" (114mm x 114mm) for high frequency use.

* This information is offered strictly as a guide to help select hinges for use in normal situations. The major factors affecting hinge selection are addressed but no attempt has been made to include extraordinary factors such as abuse, impacts, hostile atmospheres or other such conditions that can and often do affect hinge performance.

** A special hole pattern may be necessary for thin doors (such as 1 3/8"). Consult factory.
