Corner Connectors & Angle Reinforcers: The Quality Upgrade for Your Project
Maximum stability and elegant design in two perfectly matched corner connectors.
The corner connector is the ideal choice for stable frame constructions, shelves, tables, or technical installations. Its optimized triangular geometry reliably absorbs shear forces and ensures that profile connections remain dimensionally stable long-term.
The design corner connector is aimed at projects where, in addition to stability, an aesthetically clear look is desired. With its modern design, it is ideal for furniture, interior fittings, or constructions where the connector may remain visible.
Both variants feature an integrated panel receiver.
Thanks to the pre-drilled 5mm holes, wood panels, HPL, screen printing, or claddings can be directly attached at the node point – without additional support brackets. The result: clean transitions, high stability, and an aesthetically coherent construction.
Corner connector: for stable, functional frame constructions
Design corner connector: for high-quality, visible furniture and interior fitting projects
Suitable for: 20×20, 25×25 and 30×30 mm systems
The Stability Upgrade: Design Corner Connectors for Mounting Panel Material
Properly joining panel material is an art in itself. Only with a suitable corner connector do edges, lines, and transitions fit as cleanly as one expects from high-quality furniture and interior design.
When constructing furniture, frames, or functional modules, the secure and clean mounting of panel material is often the central challenge. Especially when wood, HPL, screen printing, or other panels need to be precisely connected with aluminum profiles, conventional connectors quickly reach their limits.
This is where the design corner connector comes into play: It enables a stable 90° connection and simultaneously serves as a direct fastening solution for panel material. The panel is firmly screwed to the profile – no slipping, no play, a permanently dimensionally stable unit. Ideal for side panels, shelves, tabletops, or technical installations.
Even in modern furniture construction – for example, with side tables, shelves, or room dividers – this connector ensures a high-quality result. The construction appears tidy, valuable, and well-thought-out. Furthermore, an elegant material combination is created: aluminum profiles meet wood or other panel materials and are visually cleanly guided by the visible design corner connector.
Corner Connector & Flange Connector – combinable for clean, stable connections
The corner connector can be easily combined with the flange connector. Both components are designed to perfectly complement each other and together enable a precise and resilient connection between two profiles – as shown in the picture.
The corner connector is attached directly to the profile and supports the connection made by the flange connector. This creates additional stabilization, which is particularly useful for constructions with lateral loads or larger frame areas.
The components are fully compatible and can be used flexibly together – ideal for furniture construction, frame structures, enclosures, or outdoor projects where a clean and secure connection is crucial.
The interaction of the corner connector and flange connector creates a secure, cleanly guided construction. The two elements distribute forces evenly and ensure that even larger or more heavily loaded frames reliably maintain their shape. This allows stable structures to be realized without the need for additional reinforcements or complex special solutions.
All questions answered: Material, Assembly and Compatibility
The stainless steel bracket serves the stiffening of the joint, not merely the connection. While standard push-fit connectors fix the profiles in place, this bracket absorbs shear forces and torsional loads. It is indispensable whenever your construction is exposed to dynamic forces (e.g. tables, campers, wind-resistant enclosures) and has to stand absolutely wobble-free.
The triangular shape of the angle reinforcer is designed so that you can screw wood, acrylic or metal panels directly in the corner area. The pre-drilled 5mm holes allow the panel to be fastened to the bracket, so you save on additional fasteners and achieve a very clean look.
The angle connector is designed universally for our most common square tubes:
20 x 20 mm (1,5 mm wall thickness)
25 x 25 mm (1,5 mm wall thickness)
30 x 30 mm (2 mm wall thickness)
Yes. The angle reinforcement is constructed so that it holds reliably even under demanding conditions. Whether damp rooms, garden, cat enclosure or outdoor kitchen – it remains permanently dimensionally stable and resilient.
Installation is carried out by screwing. You position the bracket at the joint (inside or outside) and fasten it using suitable self-tapping screws through the profile walls. For most applications (such as table legs) we recommend using it on the underside of the construction.
