An end cap sits on the open end of a mounting rail. It is a finishing component – neither a rail connector nor a module clamp.
Our black plastic end cap is available for profile sizes 40 × 40 mm and 42 × 62 mm. Select it to match the rail being used, not the height of the solar panel.
Inquire about the correct size.
On the end cap product page, select the profile cross-section and the required quantity. This item is ordered separately as an accessory. If you also need the mounting rails, you can find them under Mounting Profile.
The end clamp is responsible for attaching the module to the edge of the row. The similar-sounding terms therefore refer to different tasks.
