Got a tilt window that won’t stay up or is hard to open? This WRS 31 Series Constant Force Balance Coil might be just what you need! It’s a stainless steel spring that replaces the old, worn-out one in your window sash. The coil is 1/2 inch thick and designed for tilt windows—it works by providing a constant force to help the window stay open when raised and shut firmly when closed. This one is rated for 5 pounds, so you’ll need to check the stamp on your old spring to know what weight you need (for example, a 16 lb sash with single coils would need two 8 lb coils, one on each side). It’s interchangeable for left or right sides. Super durable stainless steel construction means it’ll last. If you’re handy, replacing it can save you a service call. Just make sure you get the right weight! A must-have for window repair or maintenance.
