Sash Lock

The sash lock is simply the locking mechanism attached to a window. It is most common in a single-hung or double-hung window.

Window Frame

A window frame is the window framework attached to the window edge that surrounds and supports the entire window component. It is comprised of the head jamb, side jambs, and sill. A window frame is the combination of the head, jambs, and sill that forms the exact opening in which a window sash fits.

Jamb Liner

A jamb liner is a strip that goes on a window frame's sides that provides the window sash with a snug fit.

Balance

A balance is a component present in single- and double-hung windows that use a spring mechanism to help with the weight of the sash as the window is opened and closed. Balances sit inside the window frame so they are somewhat hidden.
