Demco Products

What Demco Products does

Demco Products, operating as Dethmers Manufacturing Company LLC, is a privately held Iowa-based manufacturer founded in 1948 and headquartered in Boyden, with a second production facility in Spencer. The company operates four product divisions: agricultural equipment (sprayers, tractor-mounted fertilizer tanks, grain carts, grain wagons, and header transport trailers), semi-trailers (steel grain, liquid tender, side dump, drop deck, and gondola scrap), RV towing products (flat tow bars, baseplates, supplemental braking systems, 5th wheel hitches including Autoslide™ and Recon Stealth™, and KarKaddy™ tow dollies), and trailer components (hydraulic brake actuators, couplers, jacks, tongues, and brake lines). The portfolio includes several registered trademarks (FlexCorner®, Harvest Vision™, Autoslide™, KarKaddy™, SideQuest™, Big Buddy™) and at least one granted patent (EZ Latch Coupler, #76906732), with ISO 9001:2015 certification supporting manufacturing quality.

Revenue is generated almost exclusively through hardware sales across both B2B and B2C channels. Agricultural equipment, semi-trailers, and trailer components are sold quote-based through an extensive dealer network across the US and Canada, supported by dedicated territory managers for each product line and a dealer locator on the corporate website. RV towing products are additionally sold direct-to-consumer via the shopdemco-products.com e-commerce storefront. Pricing is not publicly disclosed; commercial and industrial products are quote-based, while select consumer RV items carry published pricing.

The company has grown primarily through acquisition, integrating Maurer Manufacturing (full 2016, partial 2001), Circle R Side Dump (2010), Hijacker 5th Wheel Hitches (2011), and SMI Braking Systems (2017) as wholly owned sub-brands. Customer evidence indicates a diversified base spanning SMB farmers, enterprise agricultural operators (Welker Farms), commercial logistics accounts (Midwest Scrap Management, Diehl & Neumaier), and individual RV consumers, with no disclosed revenue concentration. Recent strategic emphasis has shifted to product innovation, including the December 2025 Recon Stealth™ Hitch launch, the August 2025 Big Buddy™ 1300 grain cart, and AR450 abrasion-resistant steel standardization across side dump trailers.
