The Square Barebone Post for Custom Railings is a fabrication-ready stainless steel post for custom railing layouts where a standard pre-drilled post does not match the project design, field conditions, infill system, or handrail configuration.

These posts are supplied without predrilled holes for railing infill hardware, giving fabricators, contractors, architects, and experienced installers the flexibility to create project-specific hole patterns, fitting locations, mounting details, and railing assemblies.

Built from a 1 9/16" square / nominal 40 x 40 mm stainless steel profile with a 2.6 mm wall thickness, this post family supports surface-mount, fascia-mount, stair-pivot, and no-flange custom fabrication applications.

Quick Product Highlights

Common Applications

• Custom cable, glass, bar, and specialty infill railing systems
• Stainless steel, wood, and mixed-material handrail configurations
• Replacement or extension posts requiring custom hole patterns
• Decks, balconies, porches, stairs, and interior railings
• Residential, commercial, hospitality, and architectural projects
• Surface-mount and fascia-mount installations
• End, middle, inside-corner, and outside-corner locations

Intended Users

These posts are intended for experienced professionals who can complete project-specific drilling, fitting placement, fabrication, anchoring, and installation.

• Railing and metal fabricators
• General contractors and builders
• Architects and interior designers
• Professional railing installers
• Architectural metal contractors
• Experienced stainless-steel fabricators

These are not predrilled, plug-and-play railing posts. Final drilling, fitting placement, fabrication, anchoring, and installation must be completed according to project drawings, field conditions, selected railing infill, and applicable building-code requirements.

Details

Available Configurations

Mounting and Height Information

Surface-mount posts include a welded base flange. Fascia-mount posts include the selected end-or-middle, inside-corner, or outside-corner fascia flange.

Mounting anchors are sold separately and must match the supporting structure. For substrate-specific fastener guidance and recommended approaches, see Anchoring Options for Railing Posts.

For posts with a factory-welded pyramid handrail bracket, the selected 36" or 42" height represents the nominal finished railing height with the handrail installed. The handrail shown in the drawings is for reference only and is not included.

For posts without a top handrail bracket, the stated height represents the post height above the finished floor.

Special Variants

The 54 5/8" No-Flange Pyramid variant is intended for fabricators who will attach their own mounting plate, embed the post, cut it to a project-specific length, or integrate it into another custom assembly. It appears under Surface in the selector for ordering purposes only.

Refer to the technical drawings for post height, finished railing height, overall height, floor-level reference, base and fascia flange dimensions, and mounting-hole configurations.

Accessories Sold Separately

End caps, base flange covers, handrails, mounting anchors, separate handrail brackets, glass clamps, cable fittings, bar holders, infill hardware, and other railing accessories are not included unless specifically stated in the selected variant.

Compatible components are available from the Handrail Parts collection.

Installation Responsibility

Mounting hardware must be selected for the supporting structure, including concrete, structural steel, wood framing, engineered blocking, fascia framing, or other approved substrates.

The installer is responsible for confirming:

• Structural backing, anchor type, and required embedment
• Post spacing
• Handrail and infill configuration
• Required guard height
• Final drilled-hole locations and fitting placement
• Compliance with applicable residential or commercial building codes

For unusual mounting conditions, project-specific fabrication, or custom post configurations, contact Inline Design with the project dimensions and drawings before ordering.
