Slimline aluminum railing kits from Fairway Building Products come in 6- and 8-foot lengths, in two heights—36 inches for residential projects and 42 inches for commercial ones—and in two finishes, textured bronze and textured black (white is planned for later this year). Eight-foot kits are available for stairs. Top and bottom rails are cut to length on site; once balusters are inserted, the assembly is attached to surface-mounted posts with brackets. Screw heads are hidden by aluminum caps. A 6-foot-long, 36-inch-tall railing section is $177; an 8-foot section, $236. Hardware and posts are extra. Fairway Building Products,
