According to the United States Bureau of Labor Statistics (BLS), the average monthly energy costs for businesses have increased by nearly 13% per kilowatt hour (kWh). Utility providers operate legal monopolies with the freedom to increase rates whenever they deem it necessary, and our only option to keep our utility bills under control is by reducing our consumption. That’s often easier said than done, but National Custom Hollow Metal offers custom-built two-part kerf frames that can help you lower your energy costs!

We’ve been manufacturing stainless steel doors and frames right here in the USA for over 40 years, and all of our products are custom-built to your specifications. We most typically configure our kerf frames to fit 3068, 3070, or 3080 openings, but we can also manufacture doors and 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”. Our kerf frames can be built from 16 or 14-gauge 304 or 316 stainless steel or A-60 or G-90 galvanneal steel.

Our kerf 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 weather stripping forms a tight seal around your doors, and you can order replacement weatherstripping from us when it begins deteriorating near the end of its operational lifespan. It’s easier to install than screw-on or adhesive weather stripping, and it leaves no residue behind when it’s replaced.

Energy costs are always on the rise, but kerf frames are a great way to fight back without sacrificing anyone’s comfort! We include Quik Ship Service with all orders and Hot Rush and Walk Thru shipping options for distributors with tight deadlines.
