Abstract: A pair of displacement levers maximize the holding strength of hook and loop attachment devices. A first piece of hook or loop material is firmly attached to a platform. The material attached to the platform is complementary to and mateable with material attached to the other surface. The displacement levers are rotatable and connected to both ends of the platform. Rotation of the levers causes the leg sections thereof to displace the platform. This causes the hook and loop materials to move in opposite directions thereby firmly setting the hooks and loops with respect to each other and placing them in tension. Wire holding posts attached to the platform on the side opposite from the hook or loop material are used to form bends or corners in wire harnesses on wire harness forming boards. Holding devices such as clothes hooks, clamps, rings, etc. could also be attached to the platform so that other items can be supported by the device.
