. The Skyline Series Enclosure features 3/8-inch-thick glass, recessed finger pulls, and - best of all - no metal surroundings. That means no side rails, no track, and no flimsy aluminum header. Instead, the sliding panel travels on inset rollers along a simple stainless steel rod. The enclosure can be made to fit openings as large as 72 inches by 80 inches. The manufacturer declined to provide pricing. Cardinal Shower Enclosures, 800/826-2577, cardinalshower.com.
