The main element of the Guppy frame is the back-bone centre frame of light-weight aluminium which is fastened by pins to the cross-section part of the floats. They are permanently attached to the floats and define their position. The trampoline is produced from high-strength woven plastic fabric and is permanently attached to the floats for speed of assembly.
The trampoline fabric sections fill the frame and are tightly secured by a threaded line. As the trampoline is taut and the frame is tight there is no need for any additional fixings.
