The Renusol VarioSole+ End Cap (50x37, Grey) is a finishing component for VarioSole+ pitched-roof mounting rail systems, designed to close off the open ends of the 50x37mm VS+ mounting rail once an array has been installed. Supplied as a matched left and right pair, one cap is shaped for each end of the rail run, giving a complete, tidy finish across the full length of the mounting rail.
Manufactured in grey PPH plastic, the caps push-fit onto the cut ends of the 50x37mm VS+ rail profile by hand, helping to keep water and debris out of the rail channel and removing the exposed cut edge left after the rail has been trimmed to length on site.

Rail Compatibility
ⓘ Please Note: This part supplies one left cap and one right cap (a matched pair) and is sized specifically for the 50x37mm VS+ mounting rail. It is not interchangeable with the 41x35mm rail end cap or with the single dual-fit black end cap (MPN 900276) — check the rail profile and required colour before ordering.
Key Features
Matched Left & Right Pair
Supplied as one left-hand and one right-hand cap, shaped to close off both ends of a 50x37mm VS+ rail run for a complete, symmetrical finish.
Purpose-Made for 50x37mm Rail
Sized specifically for the Renusol VS+ 50 x 37mm mounting rail profile, giving a close, secure fit at the rail end rather than a generic universal cap.
Weather & Debris Protection
Capping the open rail ends helps to keep water and roof debris out of the rail channel, reducing the risk of trapped moisture and grit affecting the rail's internal fixing slot over time.
Push-Fit Installation
Each cap is pushed directly onto the cut end of the rail by hand, requiring no tools, screws, or adhesive, keeping end-of-installation finishing quick.
Durable PPH Construction
Made from polypropylene homopolymer (PPH), the caps are built to withstand continuous outdoor UV and weather exposure across the working life of the mounting system.
Genuine Renusol Part
As an official Renusol VarioSole+ system component, using the manufacturer's own end caps keeps the installation within the parameters of the VS+ system design and warranty.

Frequently Asked Questions
How many end caps are included in this listing?
This listing is for one matched pair — one left-hand end cap and one right-hand end cap — sized for the 50x37mm VS+ mounting rail.
Is this the same part as the black dual-fit end cap (MPN 900276)?
No. MPN 920044 is a grey, left/right paired cap made specifically for the 50x37mm VS+ rail, whereas MPN 900276 is a single black end cap that fits either the 41x35mm or 50x37mm rail. Confirm the rail size and required colour before ordering, as the two are not interchangeable.
Is any tool needed to fit the end caps?
No. Each 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+ 50x37mm rail. Renusol mounting equipment should not be mixed with components from other manufacturers, as doing so can void the system warranty.
Will the end caps affect the electrical bonding of the rail?
No. The end caps are non-structural, non-conductive plastic covers for the open rail ends; they play 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.
