RailFX Horizontal Cable System
This contemporary, continuous-top-rail style cable railing is one of our recommended horizontal cable rail systems, due to its seamless design, relatively easy installation, and customizability.
The basic parts include top rails, splices for joining top rails, posts, and cable kits.
- The 200 and 400 top rails are designed to be attached directly to the top of the post with two self-drilling screws.
- Splices do not need to be located above posts, splices are long enough to keep the rail straight and stiff regardless of where the seam is. Splices are secured to top rails by screwing them up through the hidden channel on the bottom of the rail.

Cables For 2-3/8" Posts
Fittings with the RailFX cables are designed to be hidden inside the posts, for a seamless appearance. cable kits include one cable and the fittings for each end. One end of the cable is raw and can be pulled through the fitting and trimmed. Once the slack is out of the cable, the other fitting has a threaded end crimped onto the cable, which is used with a hex wrench to micro-tighten another 2" or so.








RailFX Cable Post, Surface Mount for 36" Res.
RailFX is one of the few systems tested to have posts spaced 60" on center, leaving less material obstructing your view. Most systems need some sort of support for the cables every 48", meaning they have a post or baluster brace every four feet.Posts will have the top rail run over the post to hide the top surface and create a continuous top rail surface.Posts are drilled, slotted, or left undrilled, depending on the position on the deck where they are installed. End posts are use on any level surface or the top of a stair where the cables end, and the fittings are hidden inside the post. Intermediate posts are used anywhere the cable is running straight through the post on a level deck surface (or at the top of a stair). Stair slotted posts are installed partway down a stair where the cable is running through the post at a downward angle (and does not change directions). These posts will need to be trimmed to height and have a baseplate attached, depending on the placement and position on the stair.Pre-drilled corner posts are drilled so that the cable can go into the post, turn 90 degrees, and come out of the adjacent side. These are used on either internal or external corners of the deck. At the bottom of a stair, if the cable ends at the last step, use a "bottom of stair" post and trim it to height to ensure that the cables are lined up properly with the other posts. These posts have holes drilled for fittings to be hidden inside the posts, much like standard end posts.














Splices for Top Rails
Top rails can be joined with splices in straight runs, at 90 degree angles or other angles, or when transitioning from a level rail to stair rail.

Transition Brackets and Parts
Standard splices cannot be used in some applications, and special brackets will be needed for:
- Connecting a 250 top rail on stairs to a perpendicular 200 top rail on the deck
- Connecting a 250 top rail to the top of a post
- Connecting a 250 rail to the side of a post at the bottom of the stair
End plates are used to cover the end of a top rail at the end of any rail run, such as where it approaches the house wall.
