Support covers and brake shoes play a critical role in the function and safety of single and double hung vinyl windows. These components are used in constant force balance systems, which control how the window sash moves up and down and help keep the window securely locked in any open position. If a window is difficult to operate or won't stay up, a worn brake shoe or support cover may be to blame.

What Are Support Covers and Brake Shoes?

Brake shoes are locking mechanisms that fit into the window track and grip the sash, preventing it from slipping. Support covers hold and protect the coil springs in the balance system, ensuring that the constant force mechanism works smoothly. Together, these parts make sure your window sash moves easily and holds its position when open.
