Fenster universal jambliner kits fit many brands of double hung, tilt in wood windows that originally used a vinyl compression jambliner with either a square or “vee” plough shaped track. We take the guess work out of matching balances and tilt pins by offering a complete kit with all of the hardware you need to replace your existing jambliners.  If your windows have an “easy-tilt” system with slide locks to release the sashes, our jambliners will not work for your application.
