Most businesses operate with razor-thin profit margins and keep a close eye on their operational budgets at all times. Small “mom-and-pop shops” are often only a few bad months away from closing their doors for good, and large companies can easily get overextended as their operations expand. To make matters worse, utility providers operate legally sanctioned monopolies with the authority to raise rates as they see fit. The good news is that our team at National Custom Hollow Metal proudly manufactures custom-built two-part kerf frames that can help you lower your energy costs, and we can give you a quote in two hours or less!

The only remedy companies have against rising utility bills is reducing consumption, and kerf frames are a great way to do a little “belt-tightening” without sacrificing anyone’s comfort. Our kerf door frames feature a 3/32” gap that holds our Elon 490 kerf foam weather stripping, which offers superior protection from thermal transfer and can be installed in minutes without any special tools. Weatherstripping needs to be replaced at least every two or three years to ensure maximum effectiveness, and we’ll be happy to send reminders when it’s time to reorder!

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 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 Difference is Quality at NCHM, and all orders are subjected to a multi-point quality assurance inspection prior to shipping. We include Quik Ship Service with all NCHM orders and expedited shipping options for distributors with tight deadlines. Let us know when you need your frames, and we’ll ensure they’re shipped on your schedule. Most importantly, you can always order with confidence because we stand behind all of our American-made products with a one-year warranty!
