The ULAMEX “Click” end clamp completes the rapid-assembly clamp system by securing the outermost modules at the edges of every photovoltaic array — without tools, without loose bolts and without torque settings. Like its counterpart the Click middle clamp, this tool-free snap-in end clamp uses an integrated spring mechanism to achieve reliable clamping force with a single downward press. The adjustable design covers panel frame thicknesses from 30 to 40 mm, eliminating the need to stock multiple end clamp sizes on the job site. Manufactured from EN AW-6060 T6 anodized aluminum, the Click end clamp delivers the corrosion resistance, frame protection and vibration damping required for long-term outdoor PV installations. Available in silver and black anodized finishes to match both standard and all-black module designs.

How It Works — Tool-Free Installation
Installing the Click end clamp follows the same rapid-assembly principle as the Click middle clamp. Slide the clamp base into the T-slot channel of your PV mounting rail, position it at the outer edge of the last module, and press down firmly until the spring locks with an audible click. The clamp engages the panel frame’s outer edge, providing secure single-sided clamping. Because end clamps experience asymmetric loads — they grip only one module frame rather than bridging two — the spring mechanism is calibrated to deliver sufficient hold-down force even at the array periphery where wind uplift is greatest. To release, lift the spring tab with a flat-head screwdriver and slide the clamp to a new position or remove it entirely for module replacement or maintenance access.
Compatible Components
Click end clamps pair directly with Click middle clamps to form a complete tool-free mounting clamp system. Install both on aluminum PV profiles (40×40 mm and 45×40 mm). Attach profiles to pitched roofs using roof hooks, or build non-penetrating flat roof systems with ballast trays and PV tilt triangles. Additional PV fasteners and accessories are available for any bolt-on connections needed in the broader mounting structure.
Application Scenarios
Large commercial and industrial arrays: On warehouse rooftops and factory buildings with long module rows, Click end clamps are installed only at the two outer edges of each row. Their tool-free mechanism means the entire edge-finishing step takes minutes rather than the extended time required to torque conventional bolt-on end clamps across dozens of rows.
Residential installations: Homeowner installations benefit from the Click system’s simplicity and consistent quality. The adjustable 30–40 mm range means the installer does not need to carry multiple end clamp sizes for different module brands, which is common in the residential retrofit market where module selection varies project by project.
Flat roof and ground-mount projects: Whether the array sits on a ballasted flat roof or a ground-mounted steel structure, Click end clamps provide the same rapid edge-securing capability. In ground-mount configurations where arrays are particularly exposed to wind, structural engineers should verify that the spring clamping force meets site-specific Eurocode requirements.
Maintenance and module replacement: The tool-free release mechanism of the Click end clamp simplifies future module replacement. Technicians can release the edge clamps, slide out a damaged module, insert the replacement, and re-engage the clamps — all without hunting for the correct wrench or recalibrating a torque tool. This reduces maintenance downtime significantly.
Sizing Guide — Universal 30–40 mm Range
The Click end clamp adjusts to fit panel frame thicknesses from 30 to 40 mm — covering the standard dimensions of 30, 32, 35, 37 and 40 mm found on the vast majority of framed PV modules currently available in the European market. For panels with thicker frames (45 mm, 50 mm), use the standard bolt-on end clamps in the matching fixed size. For each module row, you need 2 Click end clamps per rail line (one at each end), totaling 4 end clamps per row in a standard two-rail layout. All interior positions between modules use Click middle clamps. For a fully tool-free installation, specify Click variants for both mid and end positions.
Standards and Certifications
ULAMEX Click end clamps are manufactured from EN AW-6060 T6 aluminum in accordance with European material standards. The spring mechanism is engineered to produce a clamping force consistent with Eurocode EN 1991 wind and snow load requirements for standard photovoltaic installations across Central Europe. ULAMEX is EN 1090 certified for the execution of aluminum structures, ensuring full material traceability and quality assurance. Each production batch undergoes testing for spring force repeatability, dimensional tolerance and clamping performance.

Frequently Asked Questions
Do I need both Click middle clamps and Click end clamps, or can I mix Click and bolt-on types?
You can mix Click and bolt-on clamps within the same installation. However, using Click clamps at all positions (mid and end) maximizes the speed advantage of the tool-free system. Some installers use Click clamps throughout the array interior and standard bolt-on end clamps at the edges for added wind resistance confidence — both approaches are technically valid.
How does the Click end clamp handle asymmetric wind loads at the array edge?
The Click end clamp’s spring mechanism is calibrated to provide sufficient hold-down force for single-sided clamping at the array periphery, where wind uplift is typically highest. The clamp body enhances friction between the clamp and the panel frame, increasing resistance to lateral forces. For extreme wind zones, consult a structural engineer for site-specific verification.
Can the Click end clamp be reused on a different project?
Yes. The Click mechanism is designed for repeated engagement and release cycles. As long as the spring retains its shape and the clamp is not damaged, the clamp can be removed from one installation and reused on another. Inspect the spring before reuse to confirm they are in serviceable condition.
What is the advantage of the adjustable 30–40 mm range over fixed-size end clamps?
The adjustable range eliminates the need to stock seven different clamp sizes (30, 32, 35, 37, 40, 45, 50 mm) on the job site. One Click end clamp covers the five most common frame heights, reducing inventory complexity, purchase order lines and the risk of installing the wrong size. This is especially valuable for distributors and large installers managing multiple concurrent projects with varying module specifications.
