Abstract
A casement window includes a lower hinge that has an oil-impregnated roller to facilitate easy opening and closing of the window, particularly with larger, heavier casement windows. In some instances, the lower hinge includes a housing having a roller portion and a guide portion. A roller can be disposed within the roller portion and a guide can be snap fitted into the guide portion. In some cases, a removable shipping spacer fits under the lower hinge and helps to support the weight of the sash during transport and storage.
