End Mount Low for Ballasted PV Structure Keno K-45-8 — low-profile end clamp for solar panel ballast systems

Keno K-45-8 is a low-profile end clamp designed for ballasted photovoltaic (PV) structures. It secures the outer edge of framed solar panels in ballast-mounted racking systems, providing a compact connection that maintains panel position and alignment without roof penetrations. The clamp is intended for use where non-penetrative mounting is required and where a low visual profile and reliable retention are priorities.

Advantages

The low-profile geometry reduces wind uplift exposure and minimizes the visible height of the mounting system, while the clamp's compatible design enables straightforward integration with typical ballast rails and supports. It provides stable lateral and vertical retention for framed modules and contributes to an overall streamlined ballast PV layout. The part is suited to installations where simplicity, minimal protrusion and secure edge fixation are needed.

Suitable for

• Ballasted rooftop PV systems where penetrations are not allowed or desired
• Ground-mounted ballast racking assemblies
• Framed solar modules requiring low-profile edge retention
• Commercial and residential ballast installations with space for ballast blocks

Key specifications

• Low-profile end clamp geometry for edge mounting of framed PV modules
• Designed for ballast-mounted racking applications (non-penetrative)
• Provides lateral and vertical retention for module edges
• Compact footprint to reduce visual height and wind exposure
• Material and finish compatible with outdoor PV system environments (corrosion resistant)

How to use

Position the clamp at the outer module edge on the ballast rail according to the racking manufacturer's layout and place ballast blocks as specified to achieve the required overturning resistance. Ensure the module frame sits fully within the clamp seating. Tighten the fastening hardware to the torque values recommended by the racking system instructions to secure the module without distorting the frame. Verify alignment and clearance along the module string and perform a final check of fastener tightness after initial system settling.

Usage recommendations

Use this low-profile end clamp only with framed modules and ballast racking components that are compatible in profile and fastening method. Follow the ballast system designer's guidelines for ballast quantities, placement and wind load calculations. Inspect clamps periodically for corrosion, loosening or damage and retighten fasteners after seasonal temperature cycles or maintenance activities.
