U-Shape Double-Hole End Clamp

Xiamen Honor Energy supplies U-shape double-hole clamps. As a professional supplier of solar mounting accessories, we understand how critical module edge fixing is to plant safety. It mainly consists of a U-bolt, a thickened pressure plate, and matching nuts and washers—a highly practical double-hole side clamp.

The two threaded legs of the U-bolt pass through the plate simultaneously, creating a double-point force distribution. This is far more reliable than a single-bolt side clamp. During installation, even if a worker applies a bit too much torque, it won't easily deform the aluminum frame. The pressure plate has a baked-on finish/plating, and the bolt is a hot-dip galvanized U-bolt, so rust isn't a concern.

The structure is straightforward, requiring no complex assembly. On-site installers can just tighten it with a wrench, saving significant labor time. If you're looking for a PV end clamp with strong clamping force and long-term corrosion resistance, just grab a sample of this one and put it to the test.

Application Scenarios

· Outer sections of rooftop solar arrays: For solid fixation of module frames onto rails at the perimeter of PV systems.

· Metal roof scenarios: Paired with roof clamps for fast installation, with no harm to the roof waterproof membrane.

· Ground-mounted solar plants: Hot-dip galvanized finish ensures multi-year anti-corrosion performance under tough outdoor exposure.

· Module overhaul and spare part swap: Suitable replacement hardware when existing side clamps become worn, rusted or develop damaged threads.

Advantages

1. Reliable two-point clamping design: The U-bolt exerts clamping force on two sides simultaneously, firmly securing solar modules and preventing loosening. It maintains stable fixation even under strong wind conditions.

2. Superior steel material with reliable anti-corrosion performance: A thick, uniform hot-dip galvanized coating provides full-coverage protection. Capable of long-term outdoor exposure under rain, sunlight, and other harsh conditions without rust formation.

3. Module-friendly pressure plate design: Flat, smooth edges on the pressure plate avoid scratching or denting aluminum module frames during tightening.

4. Time-saving installation: Additional supporting washers are not required. Simply position the component and fasten the nuts. Installation personnel can complete assembly rapidly, improving on-site work efficiency.

5. Broad compatibility with mainstream modules: Compatible with widely used frame thickness specifications such as 30 mm and 35 mm. Custom solutions are available for non-standard requirements upon inquiry.

FAQ

Q1: What module frame thickness does this U-shape double-hole end clamp fit? 

A: It typically fits 30mm and 35mm frames, the two most common sizes on the market. If your module has a non-standard frame thickness, just reach out to us to confirm.

Q2: Do I need to buy extra washers for installation? 

A: No. Nuts and washers come as a complete set. Just slip it on and tighten on-site—that's it.

Q3: Can I get a sample to test first? 

A: Sure. We support sample testing. Just let us know the specs and quantity you need, and we'll arrange the shipment.
