Roadmaster Base Plates - RM-521453-4

  • Removable Drawbars
  • Roadmaster
  • Twist Lock Attachment

Roadmaster's crossbar-style brackets are virtually invisible, easy to mount and simple to remove. Brackets install on your vehicle's frame to provide attachment points for your tow bar.

  • Hidden bracket design provides improved aesthetics compared with standard brackets
    • Crossbar-style brackets sit far back for a supremely clean look
  • Drawbars attach and remove quickly and easily
    • Arms click to lock in place in brackets
    • Built-in pull rings let you unlock arms so you can twist and remove them
  • Computer-cut, all-steel construction provides exceptional strength
  • Black powder coat finish is durable and corrosion resistant
  • Simple installation - no welding required
    • Custom base plates ensure a perfect fit for your vehicle
  • Integrated mounting points let you easily attach an electrical connector plug or bracket (sold separately)
  • Compatible with Roadmaster tow bars with use of quick-disconnect crossbar (910021-00 - sold separately)

The drawbars, or front arms, on the crossbar-style series base plate kit are supremely easy to mount and remove. Just insert them into the brackets and twist to lock them in place. To remove, simply twist the arms back and pull them out. Once the drawbars have been removed, the remaining brackets are virtually invisible. On most automobiles, the brackets are mounted within the grille, where they remain not only unseen, but protected from scrapes and scuffs, as well.

Great product and thanks to etrailer.com for the excellent videos detailing how to install the Demco Stay-In-Play Duo braking system. As a result of watching all of the available videos, I learned that there where a couple of different ways to install the system in our Jeep Wranglers. The first installation I did was in our 2019 Wrangler and that was super easy following the one video on your website. The second installation of the system was not as easy because our 2021 Wrangler has a manual transmission and required having to drill a hole in the firewall/floor board to run the wiring and vacuum tube from the passenger compartment to the engine area. If etrailer.com ever has an installation on a Jeep Wrangler with a manual transmission to perform, hopefully they will video tape that installation to guide customers with Jeeps with manual transmissions. I think etrailer.com's idea of mounting the control box on the fuse box is by far the cleanest and easiest way to install the Demco braking system.
I also followed etrailer.com's videos for installing the brake light system and the base plate on both our Wranglers and could not be happier with them. Thanks etrailer for all you offer.

Great product. This is the 4th unit I have purchased and used on different vehicles. When I purchased the wrong unit, etrailer replaced it with the correct one. Between the installation instructions that come with the kits and the available videos on the website, installation is relatively simple. I would and have recommended etrailer to a lot of people.

Installed these on my 2018 wrangler. Awesome instructions! Very happy with how it turned out. The videos in the web site are worth the watch.

easy to install. After 1 year not rusting at all. On a wrangler they are almost invisible compared to Blue Ox which a friend has and the entire set up is on the front end 24/7 (cross bar)

Absolutely great, easy install and hitches are hidden when the tow arms are removed , takes seconds by pulling the pin and a simple twist , I highly recommend buying this product, Installed in 2 hours on a 2020 jeep 2 door wrangler.

Recently I ordered a Roadmaster Sterling All Terrain Tow Bar (RM-576) and a Roadmaster Crossbar-Style Base Plate Kit (RM-521453-4). The included Roadmaster installation instructions were very good and easy to follow. A few minor questions came up during the installation, but eTrailer's excellent installation video by Shane cleared up any confusion. Overall the installation of both the base plates and the tow bar was pretty simple and straight forward. I think eTrailer's product and installation videos are a great help in picking the right item and installing it.
