A pre-hinged folding delta wedge that hooks the railing top or a parapet wall — drill-free. It folds flat to ship, opens on the balcony, and pins the strut anywhere from 15–30°. Two frames support each panel.

Part of the 2026 balcony series — one engineered hardware family in 6005-T5 aluminium with SUS304 fasteners, adapted to the railing and the yield you need.

Benefits

  1. Ships folded flat — the pre-hinged delta opens on the balcony and pins at 15–30°, no assembly from loose parts.
  2. Hooks the railing top or parapet drill-free, with two frames supporting each panel.
  3. Very low footprint and 300–600 W module coverage — built for compact shipping and small balconies.

Applications

Balcony railings and parapet walls — compact-shipping projects, distributor and wholesale volume.

Engineering basis

One engineered hardware family across the balcony range — 6005-T5 rails and arms adapted per railing geometry; angle hardware uses multi-hole and pinned locking (no slip, no sag). Layout and quote are matched to your wind zone from railing type and panel size.

  • DIN EN 1991 (wind actions) — 120–130 km/h holding test

Frequently asked questions

Why the folding design?

The delta wedge ships pre-hinged and folds flat — compact freight and storage. On the balcony it opens, hooks the railing top or parapet, and pins at 15–30°.

Where does it mount?

Over the railing top or on a parapet wall — drill-free, with two frames supporting each panel.

Will it hold in wind?

Wind-load tested per DIN EN 1991 — holds 120–130 km/h without slipping; the pinned strut holds its angle without sag.

Which panels fit?

Framed modules from 300–600 W; module clamps and SUS304 hardware are included, install-ready.

What warranty do I get?

A 12-year warranty in writing, on a 25+ year design life — the 6005-T5 aluminium frame and SUS304 stainless fasteners carry the service life.
