Slotted Cap Rail 90deg corner

Straight cap rail can’t be bent to create proper 90-degree corners without distorting the slot or weakening the material. This slotted cap rail corner is precision-machined to maintain the exact 24mm x 24mm slot dimensions around the full 90-degree turn. It creates a stronger, neater corner that looks professional and maintains consistent glass support throughout the direction change.

The 90-degree cap rail corner has standard 42.4mm diameter ends that connect directly to straight cap rail sections using internal joining sleeves (sold separately). The connection is invisible once installed, creating one continuous cap rail run around your entire balustrade perimeter. Each corner piece maintains the same slot width and depth as straight sections.

This 90-degree cap rail corner accommodates glass panels from 10mm up to 21.5mm thick within its 24mm x 24mm slot. The slot depth allows for proper glass seating plus glazing gaskets. Most residential installations use 15mm or 17.5mm toughened glass, both of which fit perfectly in this cap rail corner with room for secure glazing compounds.

Count every direction change in your balustrade run. An L-shaped balcony needs one 90-degree cap rail corner. A rectangular balcony needs four corners. Staircases with landings typically need 2-4 corners depending on layout. Each corner piece replaces approximately 100mm of straight cap rail, so factor this into your total cap rail length calculations.

The satin finish hides minor scratches and maintains its appearance better than mirror finishes in outdoor applications.

This is a slotted cap rail corner specifically designed for glass balustrades. The 24mm x 24mm continuous slot allows glass panels to run through the corner, creating uninterrupted glass barriers. Standard cap rail corners without slots are only suitable for handrails where glass panels aren’t required. The slotted design is essential for balustrade applications.
