In summary, the Ratchet P-Clamp, a patent-pending cable bundle and wire management solution from HellermannTyton, is suited for heavy equipment, OEM and automotive manufacturers and solar photovoltaic system service providers. The one-piece PA66 nylon solid body and stamped metal mounting plate is engineered to streamline wire harness installation, comes in four sizes and in multiple mounting configurations. Ratchet P-Clamp’s adjustable ratchet mechanism is operated manually, clicking as it closes to signal that it is secure. It also can be closed with a HellermannTyton EVO series hand tool, using an optional tension tab. The clamp is then released by inserting a small flat-head screwdriver between the ratchet rails and pushing down. Traditional P-Clamps often twist when the user torques them down, stressing the bundle. They also can pinch wires when closing and it is difficult to adjust cables during installation.
