The Renusol VarioSole+ End Cap is a small but important finishing component for VarioSole+ pitched-roof mounting rail systems, designed to close off the open end of the mounting rail once an array has been installed. Manufactured in black HDPE plastic, this single end cap is a dual-fit design compatible with both the VS+ 41x35mm and VS+ 50x37mm mounting rail profiles, giving installers one part number to stock for either rail size.
Fitted by hand with a simple push-fit action, the cap gives exposed rail ends a neater, safer finish, preventing water ingress and debris build-up inside the rail channel while removing a sharp cut edge from the roof line.

Rail Compatibility
ⓘ Please Note: This end cap is a dual-fit part and is compatible with both the VS+ 41x35mm and VS+ 50x37mm mounting rail profiles — check which rail width is used in your VarioSole+ layout before ordering to confirm the correct end cap is being specified for the job.
Key Features
Dual Rail Compatibility
One part covers both the 41x35mm and 50x37mm VS+ mounting rail profiles, reducing the number of separate SKUs an installer needs to carry on a job with mixed rail widths.
Weather & Debris Protection
Capping the open rail end helps to keep water and roof debris out of the rail channel, reducing the risk of trapped moisture and grit interfering with the rail's internal fixing slot over time.
Push-Fit Installation
The cap is pushed directly onto the cut end of the rail by hand, requiring no tools, screws, or adhesive, which keeps end-of-installation finishing quick.
Durable HDPE Construction
Made from high-density polyethylene, the cap is built to withstand continuous outdoor UV and weather exposure across the working life of the mounting system.
Low-Profile Black Finish
The black finish is designed to blend in with black VarioSole+ rail and most module frames, giving a tidier, less conspicuous appearance at the array edge compared with a bare cut rail end.
Genuine Renusol Part
As an official Renusol VarioSole+ system component, using the manufacturer's own end cap keeps the installation within the parameters of the VS+ system design and warranty.

Frequently Asked Questions
Which VarioSole+ rail profiles does this end cap fit?
This end cap (MPN 900276) is a dual-fit design compatible with both the VS+ 41x35mm mounting rail and the VS+ 50x37mm mounting rail, so the same part number can be used regardless of which of the two rail widths is fitted.
Do I need one end cap per rail or per array?
Each cut rail end that will remain visible or exposed at the edge of the array should be fitted with its own end cap. This listing is for a single end cap; order the quantity that matches the number of exposed rail ends on the installation.
Is any tool needed to fit the end cap?
No. The end cap is a push-fit component that clips onto the end of the mounting rail by hand, with no screws, adhesive, or special tools required.
Is this a genuine Renusol part?
Yes. This is a genuine Renusol VarioSole+ system component, manufactured for use with the VS+ rail range. Renusol mounting equipment should not be mixed with components from other manufacturers, as doing so can void the system warranty.
Will the end cap affect the electrical bonding of the rail?
No. The end cap is a non-structural, non-conductive HDPE cosmetic and protective cover for the open rail end; it plays no role in the rail's structural fixing or electrical bonding path, which are handled separately by the rail connectors and bonding clips used elsewhere in the VS+ system.
