Every Advanced Spa Covers comes standard with a geared, continuous leaf, heavy duty, corrosion resistant aluminum hinge. This hinge leaves only a .25” wide gap when the traditional cover has a gap of up to 1.5” under a vinyl sewn in hinge that easily tears.
The quarter inch gap left by our metal hinge is fully gasketed all across the center seam. This gasket is then pinched by the hinge when closed offering a vapor tight seal.
