Spectrum Aquatics® Elkhorn® 28500 MP400 Pool Lift. The Elkhorn® manual powered pool lift is designed for installation in the decks of in-ground and above-ground pools and spas. A single lever hydraulic ram raises and lowers the occupant into and out of the water. Ease of rotation is due to the Elkhorn’s unique 2-3/8" sleeved stainless steel anchor system; the unit is virtually frictionless.
