Securely mount your Signature series posts to your deck or floor with structural screws. The recommended screw type and length will vary by application. Follow our guidelines below for selecting the right screw for your project.
Order 4 mounting screws for each post. All screws require a T30 star drive bit to install.
To ensure the structural integrity of your guard rail it is essential to use the appropriate mounting screws for your posts. Cable Bullet offers select options designed to accommodate the most common interior and exterior applications. Properly installed, your Cable Bullet railing will withstand the applied cable rail tension (150# per cable), and secure against a 200# impact load as specified by the International Residential Code (IRC).
It is the installer's responsibility to ensure that the supporting structure is able to handle the sustained cable rail tension, and withstand an impact load to the railing.

5/4-inch Pine, Cedar, Redwood, or composite deck boards alone do not offer adequate structural support for Cable Bullet posts. To ensure maximum thread engagement and holding strength, add 3-1/2 inches of blocking under every post, for each of the 4 mounting screws.
5/4-inch tropical hardwood deck boards, including Ipe, Tigerwood, or Cumaru offer significantly more support than their softwood counterparts. 1-1/2 inches of blocking is preferred, but not necessary.
For interior applications, we recommend no less than 1/2-inch hardwood over 3/4-inch OSB subfloor, with 1-1/2-inch additional blocking preferred.
