Square Barebone Post for Custom Railings | Surface & Fascia Mount

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.

Details Post Type Square barebone post for custom railing fabrication Profile Size 1 9/16" square / nominal 40 x 40 mm Wall Thickness 2.6 mm heavy-wall construction Predrilled Infill Holes Not included. Post is supplied barebone for project-specific drilling and fabrication. Satin Stainless Steel AISI 316 stainless steel with a satin brushed finish Black Matte Powder Coat Black Matte powder coat over AISI 304 stainless steel Use Case Custom railing systems where standard pre-drilled posts do not match the design, hole pattern, field condition, or selected infill system Available Configurations Heights / Styles 42", 36" with Pyramid, 42" with Pyramid, 44 3/4" Stair Pivot, and 54 5/8" No-Flange Pyramid Mounting Options Surface, Fascia End or Middle, Fascia Outside Corner, and Fascia Inside Corner Finish Options 316 Satin Stainless Steel and Black Matte Powder Coat over 304 Stainless Steel Pyramid Bracket Option Available with or without a factory-welded pyramid handrail bracket, depending on the selected variant 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 44 3/4" Stair Pivot Post Includes an adjustable pivoting surface flange for stair and sloped railing applications. Final angle, positioning, and anchoring must be confirmed during installation. 54 5/8" No-Flange Pyramid Post Extended square post with a factory-welded pyramid handrail bracket. It does not include a surface base flange or fascia mounting plate. 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.
