solar panel Fitting clamp with Double Hole U-Bolt

SENYANG Solar Panel Fitting Clamp with Double Hole U-Bolt solve this with a single, versatile U-bolt system that fits a wide range of square tubes, C-steel purlins, and mounting rails — from 40x40mm to 60x120mm.

Every solar project has different structural profiles. Different purlin sizes. Different rail dimensions. And in high-wind zones, clamp strength is not optional.

Сайт Solar Panel Fitting Clamp Kits includes Double Hole Mid Clamps and Double Hole End Clamps, both engineered with a wide, thick profile for high clamping force and structural stability. They fit 30mm, 35mm, and 40mm panel frames — and are designed for super typhoon and hurricane regions, suitable for rooftop and ground-mounted solar mounting systems.
One kit. Multiple profiles. Extreme weather ready.

Key Advantages of our Solar Panel Fitting Clamp Kits

Our U-bolt kits fit a wide range of structural profiles:

Profile Size Application
40 × 40 mm Light-duty structures
40 × 60 mm Standard commercial frames
40 × 80 mm Heavy-duty commercial
50 × 100 mm Industrial frameworks
60 × 120 mm Large-scale ground mounts
Works with: square tubes, C-steel purlins, and mounting rails.
Note: U-bolt size and bolt length can be customized based on your structural profile. Contact us for compatibility confirmation.

Double Hole Mid & End Clamps for Solar Panel
✅ Wide and thick design – more material, more clamping force, more stability
✅ High strength – engineered for demanding structural loads
✅ Fits 30mm / 35mm / 40mm panel frames – standard and custom sizes
✅ For extreme wind zones – designed for super typhoon and hurricane regions
✅ Dual-bolt security – two mounting holes instead of one, reducing single-point failure risk

Material & Construction of our Solar Panel Fitting Clamp Kits

Clamp Body: AL6005-T5 anodized aluminum — corrosion-resistant, high strength, lightweight

U-Bolt: High-strength steel with corrosion-resistant coating

Fasteners: Stainless steel (SUS304) available

Design Life: 25+ years outdoor exposure

Middle of PV Arrays: Used to clamp the frames of two adjacent modules—the most common fixing component in any array.

Rooftop PV Projects: Works with rails for quick installation without damaging the roof.

Ground-Mounted Plants: Exposed outdoors long-term, the hot-dip galvanized material withstands wind and rain.

Module Repair & Replacement: An ideal replacement part when old mid clamps age, rust, or strip their threads.

Not all clamps are the same. Standard clamps use a single bolt. For high-wind areas, heavy-duty commercial arrays, and industrial frameworks, a double-hole design provides the extra structural stability your project needs.
