Transolid Frederick semi-frameless by-pass shower door collection combines the practicality of a space saving design with custom quality craftsmanship. The collection features thick, premium 5/16 in. (8 mm) clear tempered glass with professionally applied nano clear glass coating, which provides superior dirt and water repellant and stain resistant benefits. TruMotion technology makes our shower doors close softly and effortlessly no matter how hard you slam them or how heavy they are, and the Frederick door provides up to 2/5 in. of out-of-plumb adjustability on each side to provide a watertight fit in your alcove. Built for an alcove (3-wall) shower enclosure, sliding glass shower doors can be opened from left or right with its full by-pass (both panels slide) design. 20 in. (500 mm from center to center) sliding shower door handles also function as towel bars, providing handy storage space for a folded bath towel or two hand towels. Multiple Transolid handle options are available, but this combination features the contemporary riley handles in a polished chrome finish. The riley handles are part of the Meridian series and feature a unique, high-end design, adding a distinctive look to your Frederick shower door. These handles are substantial in weight and are every bit as functional as they are beautiful. Look for the matching grab bar to complete the look.
