Replacement Window Cranks | |
Description: | |
Cranks used for the operation of hinged windows. |
Window cranks operate hinged operating windows by cranking their sashs open or close. They are often included in casement, awning, hopper and tilt and turn windows. Blinds of jalouise windows also operate with a cranking mechanism. Although mechanized operating options are available, most homeowners prefer manual cranks since they are significantly cheaper have have a lower risk of failing to operate. They are available in a wide range of styles, colors and materials.

[edit] Styles
Window cranks are available as fold-in cranks and non fold-in cranks. Many homeowners prefer fold up crank designs because it prevents possible damage to window treatments and ensures ease of operation. Window cranks are included as part of the hinged replacement window purchase. They are generally styled and colored to match the frame.
[edit] Materials
Window cranks are generally constructed with die cast metal, though the crank casing is often plastic. These metals can be painted to match any interior window design or framing material including wood, vinyl windows, fiberglass, aluminum or composite frames.
[edit] Window Sizes
Hinged windows generally crank outward. These windows can’t be too large or too heavy because the crank must support the window during the operating procedure. Smaller and more lightly constructed windows are the best solution for windows that operate with cranks.
[edit] Window Latches
Window cranks operate in conjunction with single-lever latches or tandem latches, making them easy to open and close.
[edit] Cranking Mechanism Maintenance
Maintaining the cranking mechanism in a hinged replacement window will add years to the life of the window. Homeowners should conduct a yearly maintenance program for their hinged windows.
Windows should be opened fully and a spray lubricant should be applied to oil the crank, hinges and the lock.
The cranking mechanism's cover should be removed and a bit of light grease can be applied to the attached crank as well as to the crank gears. Operating covers can then be replaced.
[edit] Replacing a Window Crank
If crank operator become worn or there are missing splines on the crank stud, broken or stripped gears or a worn-out crank arm, it will be necessary to replace the entire crank operator. This often is the case when the crank handle spins loosely as it's turned or doesn't pull the sash far enough inward to successfully engage the locking mechanism.
If the window's overall condition is good, it is preferable to replace the crank over replacing the entire window sash. Crank handles can be replaced if only the teeth are missing but if there are worn or broken parts the entire operating mechanism must be replaced.
Crank arms must first be removed from the guide track. When the window is opened it can be cranked until the notch on the guide track aligns with the plastic guide bushing. Trim mounting screws must then be unscrewed to remove the casement cover and remove the crank. A new crank can then be installed, reversing the procedure.
