Assembling window frame assemblies often requires skilled labor at a construction site. Various aspects of the invention provide frame assemblies and methods of installing that may reduce the need of skilled carpenters on-site in some circumstances. In one particular example, the invention provides a wind ow frame assembly that includes a cover, a main frame, and a glazing pane. The cover has a transverse member that includes a mating projection. The main frame has a window opening and a confronting periphery. The confronting periphery includes a peripheral recess and a guide, with the peripheral rece ss being sized to telescopically receive a portion of the cover mating projection. The guide may include an outwardly flared guide surface that is adapted to guide the leading edge of the mating projection into the recess. The presence of the guide can greatly facilitate assembly of the cover and the main frame in a window housing.
