Outwater sells its cable-railing assemblies in a range of pre-cut lengths; builders then order the cable a little long and cut any excess in the field. Each assembly includes threaded terminals and quick-connect fittings that are easy to use and to conceal, according to the company. The 316 stainless steel cable is available in three diameters—1/8 inch, 3/16 inch, and 1/4 inch—and in lengths from 5 to 80 feet in 5-foot increments. Railings can be installed on new or existing wood or metal railing frames, in residential or commercial settings. Outwater Plastics Industries & Architectural Products , 800.631.8375, outwater.com
