Which sash component is found where two sashes meet?

The correct answer identifies the meeting rails as the component located where two sashes converge. Meeting rails are horizontal pieces that connect two vertical sashes, forming a seal when the window is closed. This design is critical for maintaining the window's structural integrity and preventing air and water intrusion.

Understanding the role of meeting rails is also essential when considering overall window performance, including insulation and security. In double-hung windows, for instance, these components play a crucial role in the functionality and effectiveness of the window operation.

Other components, like stiles and muntins, serve different purposes. Stiles are the vertical elements that make up the sides of each sash, providing structure but not functioning as the seal between the two sashes. Muntins are the small bars that divide the panes of glass within a window frame, primarily serving an aesthetic purpose. Top rails are the horizontal components at the top of each sash but do not interact directly at the meeting point of the two sashes. These distinctions clarify why the meeting rail is identified as the correct answer in the context of the question.
