Modular Frame Part Dimensions

The NRS frame system is the most adjustable and adaptable raft frame system you can buy. The heart of the system is the LoPro Frame Fitting, which allows pieces to be added, removed and adjusted for the perfect rafting or cataraft setup.

Our frames and frame parts are built right here in Moscow, Idaho by our skilled and innovative Frameshop crew. They work with specialized tools and equipment to make precisely finished parts that you can count on to fit your frame.

The diagrams below show the design specs of the system’s individual parts.
