2025 Diamond C Trailers 77″X12′ TUBE TOP PSA135 For Sale in Amsterdam, NY

The 2025 Diamond C PSA135 is a premium single-axle trailer that brings heavy-duty engineering to a nimble, lightweight frame. If you are hauling equipment through Schenectady, moving a side-by-side out to Duanesburg, or tackling a landscaping project in Niskayuna, this unit provides a level of durability that standard angle-iron trailers simply cannot match. Built with an industry-exclusive 4″ engineered channel frame, the PSA135 is designed to be stronger yet lighter, allowing for a more stable tow and easier handling on the road. The 2-3/8″ pipe top rail is permanently sealed and balled-in, creating a smooth, professional finish that is easy on your gear and hands. Serving the entire Capital Region and Schenectady County from our Amsterdam location, we recommend the PSA135 for those who want a long-lasting, high-performance trailer that stays quiet and composed even when fully loaded with a tractor or UTV.

Top Rail: 2-3/8″ Balled-end Pipe (13ga) providing a snag-free, ultra-strong tie-down surface.

What is the benefit of the bi-fold gate design on the PSA135? The bi-fold gate folds in the middle, which lowers the profile of the trailer while driving. This significantly reduces wind drag and prevents the “parachute effect,” making your tow much smoother and saving you money on fuel compared to a standard 4-foot mesh gate.

How does the Demco EZ-Latch coupler make hitching easier? The EZ-Latch is a self-latching system that automatically locks onto the hitch ball as you lower the trailer. It eliminates the need for a traditional locking pin and ensures a secure, rattle-free connection every time you head out on the road.
