EDUARD KRONENBERG GmbH has firmly established itself as the world's leading supplier of connecting elements and innovative system solutions for the insulating glass industry.
Whether the request is for straight connectors, corner keys or Georgian bar accessories, our product portfolio includes numerous variants. For all profile systems and in all dimensions, we have the right connecting element – in steel and nylon.
At the center of all projects in EK's glass business area is application technology. From a newly developed product to its continuous optimization, the specific properties of every product undergo countless series of internal tests using various test methods. These tests enable us:
[Bend & Connect]
Regardless of type, width and material, straight connectors from the EK STEEL and EK POLO Connect series are available in numerous designs. This means they can be used for all spacer profiles, whether standard or warm edge, for pre-fill and refill technology. All variants of the EK straight connectors – pre-inserted and used for subsequent frame assembly after bending – are characterized by reliable centering, optimal matching to the profile geometry, high stability and secure locking.
[Cut & Corner]
Easy insertion. Permanent grip. Extremely high load capacity. Features that distinguish our corner keys and custom corners. Custom corners are bendable and simplify the production of special-purpose and custom window panes, while providing superior dust-tight performance. And what’s more – once inserted, they do not shift from their original position.
GEORGIAN BAR CONNECTORS
[Assemble & Join]
The Georgian bar grids between insulating glass units should provide a tight fit, not rattle and be securely fixed. The wide range of Georgian bar accessories available from EK is designed for universal application and meets the highest standards required for Vienna Georgian bars (box section), Swiss Georgian bars, Georgian bar 2000 and 76 systems. Our innovative nylon end pieces and Georgian bar cross connectors from the EK POLO Connect series enable a Georgian bar grid to be produced in the same material as that used for the frame - they can also be used with both standard and warm edge profiles. The end pieces are designed to be pressed into place and screwed on to facilitate assembly.
Easy insertion - permanent and secure grip with no profile separation.
Pleasant handling, as there are no sharp serrated edges.
Excellent absorption of profile tolerances and trouble-free desiccant filling.
Extremely high stability for all spacer bar widths and frame sizes (incl. jumbo formats).
Pre-assembled and for subsequent frame assembly using warm edge hybrid profiles.
Save your strength. All you have to do is gently push the EK connector into the hollow profile as far as the second serration. When you slide the second spacer bar over the other end of the connector, as a result of its design, the connector always takes up the correct position in the profile to produce a permanent and secure seal.
Filling the spacer frame with desiccant efficiently and safe handling in subsequent operations are guaranteed for all profile widths. The geometry of our connectors has been optimized for user-friendly handling: The serrated edges are designed to ensure that the connector sits well in the palm of your hand and can be inserted into the profile with little effort.
The standard in modern insulating glass production in all widths: stable, durable, user-friendly - with secure handling and permanent connections, made of steel or nylon.
