Glass Railing Square Surface Mount Post with Handrail Bracket • Inline Design

The Glass Railing Square Surface Mount Post with Handrail Bracket is part of Inline Design’s Chicago Square Style Glass Railing System. This version includes the top handrail bracket hardware needed to support a round, square, or rectangular handrail/top rail above the glass railing posts.

Built from a 1.57" x 1.57" / 40 x 40 mm square stainless steel profile with a 12 gauge / 0.102" / 2.6 mm wall thickness, this post is a heavy-duty choice for modern glass railing systems that need clean square lines, strong post construction, and integrated handrail support.

Use it for balconies, decks, porches, patios, stairs, landings, terraces, indoor railings, outdoor railings, residential projects, and commercial projects, when installed according to local code, approved mounting conditions, glass requirements, and project-specific engineering.

Glass panels are purchased separately. This post system is designed for use with compatible tempered or laminated glass panels. Verify glass thickness, panel height, panel width, local code requirements, and project-specific engineering before ordering glass.

Important Installation Notes

Glass panels are not included. Glass must be provided by a local vendor.
Handrail/top rail tubing is not included. Select compatible round, square, or rectangular tubing based on the project design.
Base anchors are not included. Due to the variety of floor surfaces, customers must supply the connecting hardware for the base, including screws, bolts, anchor bolts, or other project-specific fasteners. For substrate-specific fastener guidance and recommended approaches, see Anchoring Options for Railing Posts.
Anchor selection must be based on the mounting surface, including concrete, steel, wood framing, blocking, or other approved structural substrates.
Stair posts and other custom posts require an additional fee to account for custom post fabrication and CAD drawings specific to the customer field measurements when necessary.
Custom fabrication requires a minimum of 1–2 weeks for production.
Handrail height, top rail layout, guardrail height, glass type, post spacing, anchoring, and other structural requirements must be verified against local code and project-specific engineering.
For coastal or high-corrosion environments, stainless steel must be cleaned and maintained regularly.

Handrail Bracket M6 Screw Direction Disclaimer

The direction of the M6 screw on the handrail bracket may vary. The M6 screw that secures the saddle on top of the post may be positioned either on the inside or the outside face. This orientation is random and depends on the production batch. We cannot guarantee a specific direction, and mixing post batches may result in variation. This does not affect structural performance.

Optional Safety Pins and Glass Notches for Surface-Mounted Posts

For surface-mounted glass railing posts, safety pins and glass notches are optional.

If safety pins are selected, matching glass notches are required for the pins to engage. Inline Design recommends two notches at the bottom of each panel, positioned for the two lower safety pins.

The downloadable drawing applies to 3/8-inch, 1/2-inch, and 9/16-inch glass. Provide it to the glass fabricator before the panel is ordered or cut.
