Bend – 90deg fixed bend – Slotted Square – 25 x 21mm

The 25 x 21mm Square Slotted 90° Fixed Bend is the corner fitting for square slotted top rail systems, maintaining the crisp, angular geometry of the 25 x 21mm profile through each 90° turn. It slides cleanly onto the open ends of both tube runs at the corner — no bolts, no screws, no adhesive — creating a sharp, precise corner that looks as though it was fabricated as a single piece.

The square profile of this fitting means the corner retains the same flat-top, flat-side geometry as the tube itself, producing a consistent, architectural line from start to finish. This is particularly important in square-tube slotted systems where the clean geometry of the design is the defining aesthetic feature.

The glass slot terminates at the fitting, providing a neat end point for glass panels on each side of the corner.

Which Grade Should I Choose?

Grade 304 is strong and reliable, suited to internal applications and external use in non-coastal, non-corrosive environments — ideal for inland areas such as Johannesburg, Pretoria, and most non-coastal suburbs.

Grade 316 (Marine Grade) offers superior corrosion resistance and is the essential choice for coastal properties, poolside installations, and any environment exposed to salt air, moisture, or chemicals. If you are in Cape Town, the Winelands, Durban, or any coastal area, Grade 316 is strongly recommended.

Installation Note

Always match your fitting grade and finish to your slotted tubing for a consistent, professional result. When fitting against glass panels, use neutral-cure silicone or clear rubber gaskets — avoid acetoxy (acid-cure) silicone as it can stain stainless steel.
