This kit includes all the hardware and cable required for a single run of railing. To calculate how many kits you need, simply count your railing sections and multiply by the number of runs: 36" Rail Height: Typically requires 10-11 runs (10-11 Kits). 42" Rail Height: Typically requires 12-13 runs (12-13 Kits). Included 2x Level Fitting Assembly 1x Pre-Cut Cable Strand Note: A "Run" refers to one row of cable railing. If your project turns a corner or hits an end post, that run terminates. You will need to start a new set of runs for the next section. Choosing Your Lag Screw Length: Select the screw length that best fits your project needs. 1.5" Lag Screw: The standard choice for attaching directly to a typical 4x4 wood posts or larger. 3.5" Lag Screw: Ideal for wall attachments where you need to penetrate through drywall, sheathing, or siding to securely reach the internal framing.
