Drop Forged Fixed Coupler 48.3X48.3mm

 

Drop forged fixed coupler 48.3X48.3mm, a durable and reliable solution for all your construction needs.

 

Precise Right-Angle Design: The inner wall of the coupler is a standard 90° angle, with a fitting degree of 99% with the steel tube. After installation, the scaffolding frame is square and stable, avoiding structural inclination caused by connection deviation.

 

Dual Fastening System: Equipped with high-strength T-bolts and nuts. After tightening, the bolts fit into the coupler grooves to prevent loosening; the serrated inner wall enhances friction with the steel tube, ensuring no slipping under load.

Hot-Dip Galvanizing Surface Treatment: The surface is treated with hot-dip galvanizing process, with a zinc layer thickness ≥ 85μm, effectively isolating moisture/acidity and alkalinity corrosion. No obvious rust after more than 5 years of outdoor use, with low maintenance cost.

 

Lightweight & High Load-Bearing: The net weight of a single coupler is only 0.8kg, easy to carry and install; however, the load-bearing performance reaches 20kN (about 2 tons), meeting the needs of heavy-duty operations such as building scaffolding and decoration frames.
