For those who like to keep their gadgets and accessories organized without sacrificing space, Series 55™ is a dream come true. It's compact, so it fits just about anywhere, making it ideal for consumers and enterprises alike looking for a sleek, space-saving solution. With options ranging from our 50mm Universal Rail to our 840mm Full Length BroncoRail™, with dozens of both universal and preconfigured rail solutions, as well as our ability to custom cut and machine to an enterprise's specific needs.

And the fun doesn't stop there; the system is designed to evolve with your needs. Whether it's patented anti-rotation trackballs, Pro Series™ clamps, or any other accessory you can think of, Series 55™ makes adding and swapping components a breeze.

Embrace the future of mounting with Series 55™, where innovation meets convenience, and your mounting possibilities are limitless. Whether you're setting up a vehicle, boat, experimental aircraft or an industrial workspace, Series 55™ is your partner in customization. Discover the joy of creating a space that's uniquely yours, effortlessly and efficiently.

More than just pretty trackballs. The Pro Series™ clamps enable arms-less connection or the chance to use the Ball2Ball™ arms.

The smallest footprint rail system on the market with either 20mm Trackballs or Pro Series™ Clamps for 20mm and 1" Balls.


Make Your Life Easier - Upgrade Any 3rd Party Generic Slotted Base

Upgrade your setup with the Series 55™ Rails from 67 Designs, evolving the way you expand and install systems on existing thin metal slotted grid bases traditionally equipped with an AMPS plate. Here's why the Series 55™ Rails are a game-changer:

Effortless Installation: Secure the Series 55™ rail to your current grid with 2-5 fasteners depending on the length of rail. It's a one-time setup that offers a lasting upgrade.

Simplified Expansion: Forget about dismantling your grid base to add more devices. With Series 55™, you can incorporate additional mounting points effortlessly, slashing the number of fasteners needed by 90% for setups involving three devices.

Versatile Compatibility: Slide on 20mm trackballs or Pro Series™ clamps anywhere along the rail with a single fastener, offering unmatched flexibility.

Unrestricted Placement: The Series 55™ rails eliminate the limitations of preset grooves found in other rail systems, including Picatinny rails, granting you complete freedom in device positioning.

Rapid Adjustments: The fastest system for adding or removing trackballs, clamps, arms, and devices on the market, making changes quick and hassle-free.

Embrace the future of mounting systems with the Series 55™ Rails and transform how you install your devices with unparalleled ease and flexibility.
