Method and apparatus for extending a window frame with extension jamb assembly

摘要

The present invention provides an assembly for extending the effective depth of a frame secured within an opening having a depth greater than that of the frame itself. A channel is associated with each segment of the frame and opens in the direction in which added frame depth is desired. Each channel has a similar, half-dovetail profile, and a frame extending member is associated with each channel. Each frame extending member has a profile that includes a first portion which is rotatable into engagement with a respective channel, and a second portion which extends in the desired direction when the first portion is retained within the channel.
