The foundation of any cable rail system is where the cables begin and end. Our DECK MOUNT TERMINAL POST is engineered specifically to withstand the applied stress when each wire rope is tensioned. Each aluminum railing post is manufactured from 6063 T6 aluminum with internal webbing. Avoid competitor hollow posts that are designed for glass infill. When the cables are tightened in these cable railings, the posts tend to deflect, so the installer must decrease cable tension to reduce the bending.

Terminal posts come either pre-drilled with powder-coated holes which eliminates many hours of installation labor, or un-drilled which are used in stairs.

The DECK MOUNT INTERMEDIATE POST mounts directly to the top surface by attachment hardware. Usually these are lag screws or concrete anchors (sold separately).


  1. Available for either 36" or 42" rail heights. 2 3/8" square
  2. 13 9mm predrilled holes (requiring 13 cable runs), for a total railing height of 42" above deck boards.
  3. 11 9mm predrilled holes (requiring 11 cable runs), for a total railing height of 36" above deck boards..

Use the CableView Railing™ WORKSHEET to design your aluminum railing system and consider the following:

  1. Are you going to DECK MOUNT or FASCIA MOUNT your posts?
  2. Which top rail will I use?
If PROFESSIONAL SWAGING SERVICE is used at both ends of the cable run: Use DECK OR FASCIA MOUNT TERMINAL POSTS for every post in your aluminum handrail, including double offset posts at the corners. This will allow the attached fitting to pass through every post in the system.

If HAND SWAGING your assemblies (RECOMMENDED): Minimum of 2 DECK OR FASCIA MOUNT TERMINAL POSTS are required for each cable run (wherever your cable begins and ends). If your cable run also has 90 degree corners, use double INTERMEDIATE POSTS at each corner. Use DECK OR FASCIA MOUNT INTERMEDIATE POSTS spaced evenly (5' Max) for the remainder of the posts. CABLE CRIMPERS and CABLE CUTTERS are required.

STAINLESS CABLE & RAILING™ only offers the best and most affordable cable rail assemblies, stainless fittings, and aluminum railing systems for your deck and balustrade railing project.

Stainless Cable & Railing offers turnkey cable railing using aluminum posts, steel posts, stainless steel posts, and wood posts. Favorite among contractors are the aluminum posts for brand new home projects or remodels. Competitor aluminum posts are not as strong as Stainless Cable & Railing aluminum posts. We designed additional webbing inside each end post to withstand the flexing. The general contractor can be assured their posts are the top in the construction business and are engineered specifically for cable railing system applications. Stainless cable rail systems start as low as $20 per lineal foot and are a terrific replacement to glass railing systems. See our videos on cable railing at or check out our deck railing designs.
