Cross connector 4-hole 57×57 mm, galvanized — ELKO-BIS 1.1 OC

ELKO-BIS cross connector 4-hole 57×57 mm is a galvanized metal fitting designed for structural joining of steel profiles, channels and frames where a four-way intersection is required. With compact overall dimensions of 57×57 mm and four evenly spaced mounting holes, this connector creates a rigid mechanical junction for metal constructions, shelving, support frameworks and industrial assemblies while offering corrosion resistance from its zinc coating.

Advantages

The connector is made from galvanized steel, providing improved resistance to rust and long service life in indoor and sheltered outdoor environments. Its four-hole design ensures stable alignment of perpendicular members and reduces the need for custom fabrication or welding. The standardized square footprint and hole placement make it compatible with common profile sizes, allowing faster assembly and reduced installation time.

Suitable for

• Assembling steel shelving and racking systems
• Joining support frames and brackets in workshops and warehouses
• Building lightweight industrial frames and enclosures
• Temporary constructions and modular assemblies requiring four-way connections

Key specifications

• Material: galvanized steel
• Overall dimensions: 57 × 57 mm
• Configuration: four mounting holes for perpendicular connections
• Surface finish: zinc galvanization for corrosion resistance

How to use

Position the cross connector at the intersection of the profiles so that each joining member aligns with one of the four holes. Secure connections using appropriate bolts or screws sized to the profile and hole diameter, ensuring that fasteners are tightened to the torque recommended for the fastener type and material. Where necessary, use washers or lock nuts to prevent loosening in vibrating environments. Check alignment during assembly and adjust as required before final tightening.

Usage recommendations

For best results, select bolts and nuts compatible with galvanized surfaces and rated for the load conditions of the structure. Avoid prolonged exposure to aggressive outdoor environments without additional protection; in corrosive conditions consider supplementary coatings or using stainless fasteners. Periodically inspect connections for loosening or corrosion and retighten or replace components as needed.
