Hot Dip Galvanized U-Type Line Joint with Positive Locking
Product Overview
During tower erection and line assembly, every structural link must carry its rated share of tension without slipping or loosening. The SLU series serves exactly this role: a family of U-shaped coupling joints rated from 10KN up to 320KN that join tower members, anchor crossarms and secure insulator strings. Each unit is CNC-machined from alloy steel, hot-dip galvanized for outdoor endurance, and fitted with matched contact faces that spread the working load evenly so the whole structure stays stable and dependable on site.

Applications
· Joining lattice tower members on overhead lines
· Mounting and securing crossarms
· Linking insulator strings into the tower
· Temporary bracing during erection work
Product Advantages
· CNC-Matched Bearing Faces — every contact surface is machined to fit, so the working load spreads evenly and the joint keeps its structural integrity from 10KN to 320KN.
· Hardened Stress Zones in Alloy Steel — critical load points are reinforced during forging, giving long service life in permanent line connections.
· Double-Layer Anti-Corrosion Finish — hot-dip galvanizing plus a weather-resistant top coat resists rust for decades of tower-top exposure.
· Locking Security with Fast Fit-Up — a fail-safe lock option prevents loosening, while pre-drilled holes and alignment slots speed up on-site assembly; a non-conductive version is available on request.
