As we begin the winter season, businesses are always looking for ways to “tighten their belts” without sacrificing the comfort of their workers and customers. That’s often easier said than done, but weatherstripping is a time-honored and economical way to significantly lower your energy bills. Our team at National Custom Hollow Metal has been manufacturing premium quality stainless steel doors and frames for five decades and counting, and we’re ready to give you a quote for custom-built two-part kerf frames in two hours or less!

We’ve been manufacturing premium-quality stainless steel doors and frames for over 50 years, and all of our products are built right here in the USA. Our kerf frames are custom-built from 16 or 14-gauge 304 or 316 stainless steel or A-60 or G-90 galvanneal steel and feature a 3/32” gap that holds our Elon 490 kerf foam weather stripping. The weather stripping doesn’t use any screws or adhesives, and it can be installed in minutes without any special tools.

Kerf frames are an excellent way to lower thermal transfer rates around exterior doors, and they can significantly reduce utility costs. To ensure maximum effectiveness, weatherstripping should be replaced every two or three years or more frequently in high-traffic areas. We’ll email you automatic reminders when it’s time to replace your weatherstripping, and you can reorder from us at any time!

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”. All NCHM orders include Quik Ship Service and a one-year warranty. We also offer expedited shipping options for distributors with tight deadlines.

Utilities are one of your most predictable expenses, and kerf frames are a great option for organizations interested in improving their overall energy and reducing their carbon footprint!
