What is a common feature of 'cripples' in wall construction?

Cripples, which are short vertical framing members, serve a specific purpose in wall construction. They are typically used to fill the spaces that occur above or below window and door openings where full-length studs cannot be used. This is important in creating a strong and stable wall structure, as it helps maintain the overall integrity of the frame while providing support for the openings.

By using cripples, builders can effectively manage gaps in the framing without compromising the structural support needed for the frame and any loads that it must bear. While it’s true that other elements of wall construction play roles in support, insulation, and electrical work, the primary and most distinctive function of cripples is to fill these partial spaces.
