U-Shape Double-Hole Mid Clamp

Xiamen Honor Energy supplies U-Shape Double-Hole Mid Clamps. It consists of a U-bolt, a thickened pressure plate, and matching nuts and washers. Designed to clamp the frames of two adjacent modules, it's a high-volume double-hole mid clamp for installation projects.

Simple in structure, but solid in force distribution. The two threaded legs of the U-bolt pass through the plate simultaneously, creating a double-point clamping action—far more stable than a single-bolt mid clamp. During installation, even if a worker applies too much torque, it won't easily deform the aluminum frame. The pressure plate edges are smooth and won't scratch module frames. Both the bolt and plate are hot-dip galvanized, resisting rust during long-term outdoor use.

Installation has no learning curve. No extra washers needed—just slip it on and tighten the nuts for fast on-site work. If you're looking for a PV mid clamp with a firm grip and great rust prevention, just grab a sample and put it to the test.

Application Scenarios

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

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

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

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

Advantages

1. Two-point clamping that actually stays put: The U-bolt pulls down on both sides at once, so the modules sit tight and don't work loose. Even on a gusty day, it's not going anywhere.

2. Real steel, real rust protection: The hot-dip galvanized layer is thick and even, covering the whole thing properly. Leave it outside for years—rain, sun, whatever—and it still won't rust.

3. Won't chew up your module frames: The pressure plate edges are flat and smooth. When you tighten it down, it won't scratch the aluminum or leave dents.

4. Quick to install: No extra washers to mess with. Just slide it on and run the nuts down. Your crew will figure it out in seconds, and it saves time on site.

5. Fits what you're already using: Works with the common frame thicknesses—30 mm, 35 mm, that sort of thing. Got something unusual? Just ask us.

FAQ

Q1: What module frame thickness does this U-shape double-hole mid 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.
