Since 1992 we have strived to be the quickest, easiest and most predictable supplier of extruded threshold products and weatherstrip to the prehung door industry. We make our products from durable 6063-T5 and 6463-T5 alloys in many anodized finishes. Our products include high quality sills, thresholds, door bottoms, t-astragals and weatherstrip. We offer full fabrication and can machine for most any specification or preparation. Our commercial sills are UL listed.
