Solar Mounting Rail Splice Joiner Kit

Solar Mounting Rail Splice Joiner Kit

The Solar Mounting Rail Splice Joiner Kit is the professional solution for extending solar racking systems. Since standard aluminum rails are typically manufactured in specific lengths (like 2.4m or 4.8m), splice kits are essential for large-scale residential and commercial projects that require longer continuous spans.

Made from high-strength Anodized Aluminium (AL6005-T5), this joiner is designed to slide into or over the rail ends, creating a seamless and rigid connection. It ensures that the rails remain perfectly straight, which is critical for the easy sliding and mounting of mid and end clamps. Each kit comes pre-assembled with SUS304 stainless steel hardware, providing a secure lock that resists vibrations and thermal expansion.

Key Features & Specifications

• Material: High-grade Anodized Aluminium 6005-T5.
• Hardware: Stainless Steel (SUS304) M8 bolts and sliding nuts included.
• Standard Length: Typically 120mm to 200mm for maximum overlap and strength.
• Compatibility: Designed to fit standard aluminum profile rails (Universal fit for most 40x40mm and H-type rails).
• Structural Integrity: Restores up to 95% of the rail's original stiffness across the joint.
• Anti-Corrosive: Anodized finish prevents "galvanic corrosion" between different metals.
• Expansion Ready: Engineered to allow for slight thermal expansion of the aluminum rails without buckling.
• Installation: Tool-friendly slide-in design for fast on-roof assembly.
