Zhengmy Solar Panel Mid Clamps 48-Pack — 1.06" Aluminum Brackets for 35–50mm Framed Panels, Corrosion-Resistant

Zhengmy 48 Solar Panel Mid Clamps are aluminum mid-clamping brackets designed to fasten framed solar panels with a 1 1/16-inch gap, delivering a durable, corrosion-resistant connection between panels and rails.

These mid clamps from Zhengmy are a practical hardware solution for installers and DIYers who mount framed photovoltaic modules. Sold in a bulk pack of 48, each clamp is machined from aluminum to resist rust and provide a clean, low-profile join between adjacent panels. They fit panels with frame-to-frame spacing around 1.06 inches (27 mm) and accommodate framed panel thicknesses from 35 mm to 50 mm, with a 5/16" (8 mm) bolt hole for standard fasteners.

How do these mid clamps improve a solar array installation?

Mid clamps create a secure mechanical link that keeps panels aligned and fixed to the rail system. By anchoring the adjacent frames, they reduce movement from wind or vibration and simplify stringing panels in series. These clamps are often used where panels sit edge-to-edge on a shared rail.

• 48-piece pack supports multi-panel arrays and spare needs
• Aluminum construction resists corrosion for outdoor use
• Low-profile design keeps panels closely spaced for neat appearance
• Universal bolt hole (5/16" / 8 mm) fits common hardware

Will these clamps fit my framed solar panels and rails?

The clamps are sized to work with framed modules that have about 1 1/16" (27 mm) clearance between frames and frame thickness between 1 3/8" and 2 11/16" (35–50 mm). They fasten through an 8 mm bolt hole, so check your bolt dimensions and rail slot compatibility before installing.

• Designed for framed panel gap: ~1.06" (27 mm)
• Compatible framed thickness: 35 mm to 50 mm (1 3/8"–2 11/16")
• Bolt hole diameter: 5/16" (8 mm) — confirm with your rail fasteners
• Not intended for frameless (glass-glass) modules without adapter

How easy is installation and what tools are needed?

Installation is straightforward: position the mid clamp between panel frames on the rail, align the bolt hole, and tighten the mounting bolt. No special tools are required beyond standard wrenches or a socket set, making these clamps suitable for both professional crews and competent DIY installers.

• Simple mount-and-tighten workflow saves installation time
• Use common wrenches or sockets matching 5/16" bolts
• Bulk pack reduces trips to retrieve more hardware
• Follow manufacturer torque specs for secure mounting

What are the durability and maintenance considerations?

Made from aluminum with a smooth finish, these clamps are built to withstand outdoor conditions without quick corrosion. Periodic inspection is recommended to ensure bolts remain tightened and there is no unexpected movement, especially in high-wind or coastal environments.

• Aluminum alloy resists rust and maintains appearance
• Minimal maintenance: visual checks and bolt re-torque as needed
• Replacement is simple thanks to the 48-pack supply
• Avoid contact with dissimilar metals without appropriate coatings

Who is this for: Zhengmy 48 Solar Panel Mid Clamps suit solar installers, contractors, and homeowners installing framed PV modules who need a reliable, cost-effective mid-clamp solution in bulk. Choose these clamps if you want corrosion-resistant aluminum hardware that fits common framed panel dimensions and simplifies multi-panel mounting jobs. Verify your panel frame gap and bolt sizes before purchasing to ensure a proper fit.
