Installation

Before installation, accurately mark the fixing positions and verify that the supporting structure is suitable for the expected loads. The chemical-anchor end of the Ø16 × 320 mm rod is fixed into the wall or façade structure, while the glass holder is connected using the M8×25 mm internal thread.

The glass panel must have a hole with a minimum diameter of Ø18 mm. Suitable glass protection gaskets must be used to prevent direct contact between the glass and metal components. The chemical anchor, installation depth and other fixing elements should be selected according to the base material, façade structure and calculated design loads.

Fixing Elements

The chemical anchor and other structural fixing elements are not included, because their specification depends on the wall, concrete, masonry or other supporting structure. Suitable fixing elements should be selected according to the base material and expected structural loads.
