If there’s one thing that small businesses have in common with large corporations, it’s the need to manage costs. Some businesses experience cyclical periods of prosperity, followed by lean times during the off-season. Other companies that are fortunate enough to experience steady business year-round have to pay close attention to their competitor’s prices to ensure their continued success. Utilities are one of your most predictable expenses, and a little belt-tightening can make a large difference. National Custom Hollow Metal offers custom-built two-part kerf frames that can help you lower your overall energy consumption, and we can give you a quote in two hours or less!

We’ve been manufacturing premium-quality stainless steel doors and frames for 50 years, and all of our products are built right here in the USA. Utility companies are legal monopolies that can raise rates as they see fit, and the only way to fight back is by reducing your energy consumption. Kerf frames are a great way to lower thermal transfer rates around frequently used entrances and exits, and they can make a significant difference in utility costs without sacrificing the comfort of the building’s occupants.

Our kerf frames are custom-built from 16 or 14-gauge 304 or 316 stainless steel or A-60 or G-90 galvanneal steel. We most typically configure our kerf frames to fit 3068, 3070, or 3080 openings, and we can also manufacture frames in custom sizes to your specifications. The jambs are configured to a 5 ¼” minimum depth for a 1 ¾” door or a 4 ⅞” minimum depth for a 1 ⅜” door, up to a maximum depth of 20”. The frames feature a 3/32” gap that holds our Elon 490 kerf foam weather stripping, which can be installed in minutes without any special tools. The weatherstripping needs to be replaced at least every two or three years to ensure maximum effectiveness, and we’ll email you automatic reminders when it’s time to reorder!

We include Quik Ship Service with all NCHM orders and offer Hot Rush and Walk-Thru service for distributors with tight deadlines. If you have any questions or would like to receive a quote in two hours or less, contact us online or dial 800-334-3070. Email us at [email protected].
