Deck railings are essential for safety and aesthetics, and cable railing systems are gaining popularity for their sleek, modern design. Here’s everything you need to know about DIY cable railing for decks.

Benefits of Cable Railing

Aside from providing safety, cable railing offers several benefits:

• Clear Views: Thin horizontal cables provide clear views compared to bulky wooden or vinyl bars.
• Modern Style: The sleek design completes contemporary architecture, especially with metal posts.
• Durability: Stainless steel cables withstand intense environmental conditions.
• Low Maintenance: Requires significantly less maintenance than traditional wooden railings.

Is Cable Railing Safe for Decks?

Yes, cable railing is safe when properly installed and maintained. This system should comply with local code requirements to ensure safety. Cables must be tensioned correctly, and the railing should be regularly inspected for wear or slack.

Cable Railing Code Requirements

• Height: Railings must be at least 36 inches tall for residential and 42 inches for commercial settings.
• Spacing: The space between cables should prevent a 4-inch sphere from passing through to protect children and pets.
• Force & Load: Railings must withstand 200 lbs of concentrated force in any direction, with intermediate structures needing to handle 50 lbs.

Always consult local building codes for accurate regulations specific to your area before installation.

Cable Railing Posts and Hardware

A cable railing system is made up of several components, each falling into one of four categories:

• Posts: These are the primary structural elements of the system, typically made from metal or wood.
• Handrail: Often made of wood or metal, the handrail supports individuals near the railing.
• Fasteners: These are the small components that secure and tension the system. Bellointeriors, fasteners come in kits designed to mount the infill or tension the cables at the end of each railing run.
• Infill: Refers to the cable wires themselves. Bellointeriors also offers metal rod infill as an upgrade, providing the same look as cable but with enhanced durability and a modern, powder-coated black finish.
