Steel Railing Frames - Construction Requirements



See important notes on the main Frame Requirements & Details page before beginning your project.

End & Corner Post Minimum Sizes


The end and corner posts need to be strong enough to support the full tension load of the cables. Below are the recommended minimum sizes for the end and corner posts only. The intermediate posts do not support any tension load and only need to be sized as necessary to support the cap rails and meet code requirements.

Steel Railing Frames - The Details



Cable assemblies are strung horizontally and may either be terminated at corner posts or run continuously through the corners. Details of these conditions are shown below:

Running Cables Continuously Through The Corners

Single Pipe
Double Pipe
Double Flat Bar
Angle Iron
The detail for square tubing would be the same as that shown for round pipe.

Terminating Cables At Corners

Rubber grommets #3213 (for 1/8" cable only) may be inserted into the 1/4" holes on tubular posts to add a finish detail for intermediate posts only - not for corner or end posts.

All decks and railings are unique; therefore, slight variations in the installation procedures and frame designs may be necessary depending on your specific conditions. If you need assistance or have questions please give us a call at 1-877-810-4116.
