This deck cable railing kit features a sleek and elegant new design. Its main components are made of T316 stainless steel, which offers rust resistance, water resistance, and corrosion resistance, meeting marine-grade standards. Suitable for both indoor and outdoor use, it can be used for DIY stair railings, porch railings, patio railings, and deck railings. The 100-piece kit comes with a wrench to facilitate easier and faster installation. This railing hardware is compatible with cables of 1/8-inch outer diameter in cable deck railing systems. The threaded expansion screws are specifically designed for wooden posts, they can rotate the steel cable in the same direction, preventing twisting of the connected cables and extending the service life. During installation, the cable length should be 1-1/2 inches shorter than the distance between the wood surfaces. It is recommended to match it with standard 1/8-inch outer diameter cables made of T316 stainless steel to create a high-quality system. The expansion screws can be directly drilled into the wood to adjust tightness, eliminating the need for additional turnbuckles or tensioners. Additionally, the railing system does not block the view. A basic economical cable railing system typically includes 1/8-inch expansion screws (Model DM50), 1/8-inch steel cables, a cutter (Model DW40), and a hydraulic crimping tool (Model DC01).
