Cross connector ELKO-BIS 4-hole 57×57 mm galvanized, model 1.2 OC

ELKO-BIS cross connector model 1.2 OC is a galvanized 4-hole metal connector with plate dimensions of 57×57 mm, engineered to join profiles or structural elements at a cross intersection. The compact square plate with four mounting holes provides a stable mechanical connection between perpendicular members and the galvanization layer increases resistance to corrosion in indoor and sheltered outdoor environments. This connector is suitable where a small footprint and reliable load transfer between intersecting metal profiles are required.

Advantages

The galvanized steel construction delivers consistent corrosion protection and long service life in typical construction and shelving applications. The four-hole layout ensures even distribution of fastening forces and simplifies alignment during installation. The 57×57 mm plate size offers a compact solution that fits within constrained assemblies while maintaining adequate bearing area for bolts or screws. The connector’s simple geometry makes it compatible with a range of standard metal profiles and structural members.

Suitable for

• Joining metal framing profiles at right-angle intersections
• Shelving supports and storage rack assemblies
• Light structural connections in workshops, utility enclosures, and interiors
• Repair or reinforcement of existing cross joints in metal constructions

Key specifications

• Material: galvanized steel
• Plate dimensions: 57 × 57 mm
• Hole count: 4 mounting holes
• Geometry: square cross connector for perpendicular joints
• Surface finish: zinc galvanization for corrosion resistance

How to use

Position the cross connector at the intersection of the two profiles so that the holes align with predrilled or marked attachment points. Use appropriate fasteners (bolts, nuts, or self-tapping screws) sized to the connector holes and compatible with the profiles being joined. Tighten fasteners to the torque recommended for the chosen bolt or screw grade and profile thickness, ensuring even compression and avoiding over-tightening that could deform the plate or reduce coating effectiveness. If used outdoors or in high-humidity environments, verify that the fasteners have comparable corrosion protection.

Usage recommendations

Select fasteners with diameter and length suited to the plate hole size and the thickness of both profiles to ensure secure load transfer. For load-bearing or safety-critical installations, evaluate the required mechanical capacity and follow relevant structural guidance or standards. Store connectors in dry conditions to preserve the galvanization and avoid contact with dissimilar metals that can accelerate corrosion.
