A stainless steel round tube of Ø 33.7 or 42.4 mm (2 mm wall thickness). For maximum burglary protection, optionally with shear nuts to prevent unauthorized removal.
They serve as mechanical burglary protection for windows (especially on the ground floor and in basements) and at the same time as fall protection or a French balcony for floor-to-ceiling windows – a modern, discreet alternative to window grilles.
High-quality, rust-free 1.4301 (V2A) stainless steel, brushed. The wall-mounting elements are also made of stainless steel. Manufactured in Germany.
You specify the mounting distance in mm; we manufacture made to measure. The mounting distance corresponds to the exact reveal dimension of your window opening in mm – that is, the clear dimension between the two reveal walls on which the bar is mounted. Please measure precisely, as the Security Bar III is fitted into the reveal with an exact fit. The slip-on sleeves give us an installation clearance of 5 mm – so the bar can be inserted without any problem despite being made to measure.
The mounting kit is selected separately to match the wall: standard masonry (brick/aerated concrete), thermal insulation (ETICS, with thermal separation against cold bridges), or timber-frame construction.

After a long search, we discovered this shop. Great service, very friendly and competent advice. Top quality. When purchasing from the online shop, the various options are clearly displayed, which makes selection and purchase easier. Payment also possible via PayPal. The delivery announcement by the forwarding agent worked well. The window grille was carefully packed and delivered. We will definitely be ordering more window grilles here. Purchase August 2025; UPDATE: We have become repeat customers and bought another window grille from Kirchberger in November - absolutely satisfied - fits together perfectly.
