Suspension mounting system for Flash 737e stringing machines:

Six-point mounting system provides 10-point maximum supports and eliminates any racquet distortion. Head and throat mounting posts could move in and out without any adapter. Single-action quick mounting arms (heavy-duty): turn a single knob to control both mounting arms. Large padded, L-shaped rotating shoulder supports rotate to perfectly fit against the frame. Padded head and throat mounting posts secure any frame (including deep V-shaped throats), no cosmetic damage to any frame.
