Roadmaster 521448-4 Crossbar-Style Tow Bar Baseplate Kit with Removable Arms

The Roadmaster 521448-4 is a Crossbar-Style Tow Bar Baseplate Kit with Removable Arms, engineered for flat towing your vehicle behind a motorhome or RV. The crossbar-style brackets are virtually invisible, easy to mount, and simple to remove, installing directly on your vehicle's frame to provide solid attachment points for your tow bar.

Key Features:

• Removable arms designed for easy attachment and removal, accommodating various towing setups
• Front arms are easily removed when the vehicle is not being towed
• Provides a strong, secure mounting point for tow bars that utilize a crossbar or quick-disconnect system, constructed from high-quality steel that resists rust and wear over time
• Custom-fit design integrates into the frame and undercarriage of the vehicle, connecting to existing holes and fasteners wherever possible for quick, easy installation
• Every baseplate is powder-coated with a baked-on finish for long-lasting corrosion resistance
• Roadmaster was the first towing products manufacturer to use computerized stress testing — as well as real-world physical testing — on baseplates to ensure structural integrity and safety
• Made in the USA; covered by a limited lifetime warranty against defects in material and workmanship

Ideal for car-mounted tow bar setups needing additional accessory support. Note: this crossbar-style baseplate is designed for use with a car-mounted tow bar such as the Roadmaster StowMaster. If using a motorhome-mounted tow bar such as the Roadmaster Nighthawk or Falcon, a crossbar adapter (#37674) is required.
