Mounting bracket 90° for MG/MF/MH profile, Niczuk XX3 (MPN 81141030900)

The Niczuk XX3 90° mounting bracket is designed to create a rigid perpendicular connection between MG, MF and MH aluminium profiles. Intended for mechanical fastening in industrial and workshop environments, the bracket provides a stable joint for framework assembly, machine guards, enclosures and structural supports where a fixed right-angle connection is required.

Advantages

This right-angle bracket offers precise alignment and consistent 90° geometry for connecting MG, MF and MH profile sections. Its design ensures mechanical stability under static loads and simplifies assembly by providing a clear reference surface for tightening fasteners. The bracket supports repeated mounting and disassembly without compromising joint integrity, making it suitable for maintenance and retrofit work.

Suitable for

• Building frames and supports from MG, MF and MH aluminium profiles
• Mounting machine guards, panels and enclosures with rigid corners
• Constructing workstations, shelving and fixtures requiring fixed right angles
• Industrial and workshop assemblies where mechanical fastening is preferred

Key specifications

• Function: fixed 90° corner connector for aluminium profile systems
• Compatible profile series: MG, MF, MH
• Material and finish: metal bracket suitable for mechanical fastening (material type depends on manufacturer specification)
• Connection method: fastened with screws/bolts to profile slots or faces
• Application environment: industrial, workshop and production settings

How to use

Position the bracket at the intended junction of two profile sections ensuring correct orientation for a right-angle joint. Align the bracket faces with the profile faces or slots and insert appropriate fasteners through the bracket holes into the profile T-slots or threaded inserts. Tighten fasteners to the torque recommended for the chosen screws and profile system to achieve a secure, rigid connection. If disassembly is required, release the fasteners and remove the bracket; inspect mating surfaces and fasteners for wear before reassembly.

Usage recommendations

Choose fasteners compatible with MG/MF/MH profiles and the installation environment; verify material compatibility and tightening torque to avoid deformation of profiles or loss of preload. For load-bearing or safety-critical assemblies, follow applicable engineering guidelines and, where needed, use washers, thread-locking compounds or additional reinforcement to ensure long-term stability.
