Dethmers Mfg Co Trailer Parts & Accessories

Dethmers Manufacturing Company, widely recognized under its Demco brand, has been a trusted name in the towing and trailer industry for more than five decades. Based in Boyden, Iowa, the company began with deep roots in agricultural machinery before expanding its engineering expertise into trailer components and towing accessories that RV owners, haulers, and working drivers rely on every day.

When it comes to the Trailer Parts & Accessories category, Dethmers brings the same commitment to innovation and durability that earned the brand its reputation in the field. Their trailer product lineup addresses some of the most safety-critical and performance-sensitive aspects of towing — the kind of components where quality truly matters.

What Dethmers Mfg Co Offers in Trailer Parts

Dethmers' trailer parts catalog spans a range of essential components for both recreational and utility towing applications. Key product types include:

• Hydraulic Brake Actuators — Demco hydraulic actuators, such as their A-frame drum brake actuators, are engineered for precise, reliable braking performance. Available in multiple ball sizes and tongue configurations, these actuators are a go-to choice for trailer builders and repair technicians alike.
• Trailer Brake Components — From galvanized hydraulic single-servo brakes to complete brake assemblies, Dethmers offers components designed to withstand the demands of heavy trailer loads across a range of weight ratings.
• Towed Vehicle Tail Light Wiring Diode Kits — Proper electrical wiring is essential for safe towing. Demco's wiring diode kits provide a clean, reliable solution for integrating towed vehicle lighting with the tow vehicle's electrical system — a must-have for flat towing behind an RV.
• Tow Bars, Dollies & Hitches — Dethmers rounds out its trailer accessories offering with tow bars and tow dollies engineered for smooth, secure vehicle transport.
