Connector LPRO 90 straight AKS 40x90 / 60x90 (model 111441)

The AKS LPRO 90 straight connector (model 111441) is designed to join structural aluminium or steel profiles with cross-sections 40x90 mm and 60x90 mm in a straight, rigid 90° alignment. It fits framing systems where those profile dimensions are used and provides a consistent interface for assembling frames, enclosures, and modular constructions. The connector is intended for mechanical fastening of mating profile ends and for creating durable right-angle joints within industrial and workshop environments.

Advantages

The connector provides a precise 90° alignment for compatible 40x90 and 60x90 profiles, enabling repeatable and stable joints without the need for complex machining. Its geometry supports straightforward assembly with standard fasteners and allows for easy integration into existing framing systems. The part is suitable for both load-bearing and non-load-bearing joins, offering structural continuity across connected profile sections.

Suitable for

• Assembly of machine frames and equipment guards using 40x90 or 60x90 profiles
• Construction of enclosures, cabinets and access panels where right-angle joints are required
• Modular structures, workstations and shelving systems built from compatible profiles
• Retrofit or extension of existing framing systems that use the same profile cross-sections

When it may not be suitable

This connector is not intended for profiles with cross-sections other than 40x90 mm or 60x90 mm and will not provide correct fit or alignment on incompatible profile sizes. It is designed for straight 90° connections; applications requiring adjustable angles, articulating joints, or non-rectilinear connections will require different connectors or custom brackets.

Key specifications

• Compatible profile cross-sections: 40x90 mm and 60x90 mm
• Connection type: straight 90° rigid joint for profile ends
• Material compatibility: suited for common structural aluminium or steel profile systems
• Use environment: indoor industrial, workshop, and protected outdoor applications when appropriate corrosion protection is provided

How to use

Position the connector at the ends of the two matching profiles so that the faces align at 90°. Secure the connector to each profile using the appropriate fasteners recommended for the profile system (bolts, T-nuts or screws), ensuring correct engagement and torque per the profile manufacturer’s guidance. Check alignment with a square and tighten fasteners progressively to avoid misalignment. For load-bearing assemblies, verify that additional supporting brackets or gussets are used as required by the structural design.

What to consider before purchase

• Confirm that your profiles have cross-sections 40x90 mm or 60x90 mm and that the connector geometry matches your profile system.
• Verify which fasteners and accessories are needed for secure attachment (bolts, T-nuts, washers) and whether they are included or must be purchased separately.
• Consider the expected load, orientation and environmental exposure to determine if supplemental reinforcement or corrosion protection is required.

Usage recommendations

Use the connector with matching-profile fastening hardware and inspect joints after initial assembly and periodically during service. For structural or safety-critical installations, follow engineering specifications for fastener torque and use additional reinforcements when required.
