A Fenster sash rebuild kit (SRK) is a new wood sash frame used to rebuild your existing sash. The kit includes all four sides and new weatherstrip. The kit does not include new glass, cladding or hardware. Our casement sash kits are exact copies of the original design to match your existing window sash.

We offer a limited selection of double hung sash kits due to volume. Please see our model catalog for available models listed. We have many double hung brands/models available through our millwork dept. sold as millstock parts only. See our millstock page for more information.

A Fenster replica sash is a complete replacement sash for a painted casement window. Our replica sashes are nearly identical to the original with the exception of obsolete boot glazed models that have been upgraded to our more advanced wet-seal technology.

Fenster Quiksash is a complete replacement sash for a clad-wood window. Our replica sashes are nearly identical to the original with the exception of obsolete boot glazed models that have been upgraded to our more advanced wet-seal technology

A Fenster Quiksash kit includes the upper and lower sash set with a new pair of vinyl compression balance kits. Quiksash is designed to fit any brand or model of painted wood or clad wood double hung window that originally had vinyl compression jambliners. This is the only product we offer for a complete double hung sash. If you are looking for brand specific parts, please see our millstock page for available profiles.

Fenster balance kits, AKA, jambliners are a complete set of left and right vinyl tracks with heavy duty balancers installed. The kit comes complete with all the hardware you need for a quick and simple installation. Fenster jambliners come in industry standard track shapes, colors, and rough opening lengths so they do not have to be brand specific. They fit nearly any brand of double hung tilt-in wood window that originally had vinyl compression jambliners.

We stock a wide variety of weatherstrip, seals, glazing beads and stops that we commonly use on our replica sash models. We do not carry brand specific parts. We may substitute an alternate product that matches, resembles or improves the performance of the existing sash on our replica model.

Our new millstock dept. is coming mid-2018! Fenster will now offer its extensive catalog of sash profiles in 6 ft lengths for casement and double hung. In the meantime, while we build out this page, please contact sales, windowparts@fensterusa.com, to make a millstock request.

Fenster does not sell window hardware in general. In fact, window hardware is not brand specific. Most major brands, with the exception of Pella, Andersen, and Marvin, used TRUTH brand hardware. We offer a very limited assortment of the most common TRUTH hardware. Please contact sales at windowparts@fensterusa.com with your hardware request. We suggest searching for TRUTH hardware online to find one of the many online window hardware companies for a more extensive selection.
