Zero #4, 400, 4000 Metal Weatherstrip, Wooden Windows, for Upper Sash Jambs
These Zero #4_400_4000 metal weatherstrips are compatible with double-hung wooden windows. When installed along the jambs of the upper sash, the protruding design corresponds with a cutout in the window frame and interlocks to create a barrier, which prevents draft infiltration and rattling due to faulty installation. Available in three designs (see product specs), and comes in a choice of either Zinc or Bronze Mill Finish.
SOLD IN STRIPS OF 4,5,6,7,8 FEET
This product is part of our series of metal weatherstripping for double-hung wooden windows. For a complete window weatherproofing job, please see our corresponding products detailed below.
How to order: To calculate amount needed to weatherstrip both upper sash jambs, measure upper sash height and multiply by two. As this product is sold in pre-cut strips of 4,5,6,7,8 feet, round up to the nearest of these length options and choose that amount from the 'Length' drop-down box below. To order multiple strips in that length, indicate amount in the ‘quantity’ drop-down box. Strips can be easily cut with shears.
This interlocking metal weatherstrip is compatible with double-hung wooden window frames. When installed, the protruding design corresponds with a cut out in the door / window frame and interlocks to create a barrier which prevents draft infiltration and rattling due to faulty installation.
The weatherstrip has a total width of approx. 1.750" and the raised portion has a height of .390". It requires a cut out of .125" (W) x .45" (H)- see product specs. It is easily applied with wood screws. Sold in pre-cut lengths of 4,5,6,7,8 feet.Â
This upper jamb metal weatherstrip comes in three designs, with a return flange, ridged, and smooth (see product specs and applications tab). A return flange allows for smooth sliding of the window as well aids in closing a slightly larger gap around the window frame . A ridged design aids in larger gap closure between the frame and jambs. The smooth design is the thinnest, requiring the least clearance between the frame and jambs.
Product Z4: Has a return flange and is ridged
Product Z400: Ridged only
Product Z4000: Smooth
To install, either remove or lower the upper sash window and measure and trim metal weatherstrip to jamb height. To create the corresponding groove in the window frame, use a circular saw to make a cutout measuring .125" (W) x .45" (H) along the window frame. Nail the metal weatherstrip in place after testing that the window interlocks and slides smoothly.

A note on metal options: Available in Zinc and Bronze Mill Finish. Zinc is a silvery, white metal with a long lasting, maintenance free life. It does not rust easily, making it an ideal option for external windows. Bronze Mill Finish is a solid bronze piece, which increases longevity and aesthetics, thus the large increase in price. It resists corrosion and does not rust. For more information see Understanding Metals and Finishes.
