Gamma2 Skamper Ramp SK-LGE Large Skamper Ramp. This simple white, recyclable, plastic ramp attaches to the side of the pool, walled pond/lake, most docks, and even many boats. Because all living beings see objects that reflect 550 nm-wavelength (white) light, animals can see it any time of day, and they "skamper" out on the ramp to safety.
