The Signature Cable Railing, Surface Mount, Flat Top Level Passthrough Post “A-5” is the intermediate post for level runs. Pre-drilled with level 5/16″ holes on both sides, cable passes cleanly through the post without any additional fittings or hardware – keeping installation fast and the finished look clean.

Stainless models are also available in a brushed finish. Standard colors include Textured Black, White, and Silver. Premium powder coat options are available for larger projects or custom color needs.

The Flat Top cap delivers a clean, minimal profile. Available in 36″, 39″, and 42″ heights. All posts are made in America. Pair with Universal Top posts wherever level and stair runs meet.
