Knappco Corp
Locations

Based in Kansas City, MO, Knappco Corporation is a specialized manufacturer of industrial access ports, manholes, hatches, coamings, collars, weld rings and fill covers. In other words, virtually every key component needed to keep a lid on hazardous bulk commodities while they're handled or transported.
So, halfway around the world, a state of the art petrochemical refinery shares one thing in common with a grain elevator in Iowa or cargo tankers moving commodities over-the-road and on rails - they all depend on Knappco Corporation products & accessories.
Whatever your base application, wherever your base of operation, Knappco covers your needs with precision engineered and manufactured manholes, fill covers, pressure vacuum hatches, valves and more. Our ability to meet the requirements of a wide range of industries and applications is only a part of the story. Our commitment to exceeding customer's expectations for over 50 years is the true measure of our success.
