The Renusol VarioSole+ (VS+) mounting rail (Part No: REN-400572) is an aluminium rail profile supplied at 41 x 35mm in a 3.6m length, designed for use within the Renusol VS+ on-roof mounting system for pitched roofs. It forms the load-bearing rail component that connects to roof hooks, hanger bolts, or standing seam clamps, and in turn carries the universal module clamps that secure PV panels in place.
The VS+ system is built around two rail profiles for different load classes — this 41 x 35mm profile is the medium-load rail, paired with a larger 50 x 37mm profile for higher-load applications. Both are part of the same modular VS+ platform, so roof hooks, clamps, and connecting hardware are shared across the range, simplifying stock and installation on mixed projects.

Important: Renusol Components Only
The Renusol VarioSole+ system is designed exclusively for use with genuine Renusol mounting hardware. Combining this rail with roof hooks, clamps, or fixings from other manufacturers will void the system warranty and may compromise structural stability — do not mix components across brands.
Please Note: Confirm Rail Selection Before Ordering
VarioSole+ rails are supplied in two profile sizes — this listing is the 41 x 35mm medium-load rail. A separate 50 x 37mm high-load rail is also available in the range for installations with greater span or loading requirements. Check your project's structural calculation (via the Renusol PV Configurator or your designer) to confirm which profile is specified before ordering.
Good to Know: Structural Design Support Available
Renusol provides a free PV Configurator design tool that generates a full assembly plan, parts list, and structural calculation — including wind and snow load import — for VS+ installations. This is the recommended route for confirming rail spans, fixing centres, and load compliance for your specific roof and module combination.
Modular VS+ Platform
Part of Renusol's modular VarioSole+ system, where roof connection, rail, and clamping components are interchangeable across projects — reducing the range of parts an installer needs to stock.
Medium-Load Profile
The 41 x 35mm cross-section is engineered as the medium-load option in the VS+ range, giving a lighter, more cost-effective rail for installations that don't require the larger 50 x 37mm profile.
Universal Roof Compatibility
Designed to work with roof hooks, hanger bolts, and standing seam clamps, allowing the same rail to be used across tile, slate, sheet metal, sandwich panel, and fibre-cement roof coverings.
Adjustable Clamping
Pairs with Renusol's universal module clamps, which adjust for different PV frame heights and support both horizontal (landscape) and vertical (portrait) module orientation.
Aluminium Construction
Manufactured in aluminium for a strong, corrosion-resistant, low-weight rail that keeps dead load on the roof structure to a minimum over long spans.
TÜV & MCS Certified
Certified under TÜV ID 1111212485 and MCS012 IK0197/03, supporting compliance documentation for UK domestic and commercial PV installations.

What roof types is this rail suitable for?
The Renusol VS+ system covers tile, slate, sheet metal, sandwich panel, and fibre-cement roof coverings, on roof pitches between 10° and 45°, using the appropriate roof hook or fixing for the covering type.
Can I mix this rail with roof hooks or clamps from another brand?
No. Renusol specifies that VS+ components must only be used with genuine Renusol mounting hardware. Mixing brands will void the system warranty and may affect structural performance.
What's the difference between this rail and the 50 x 37mm VarioSole+ rail?
This 41 x 35mm rail is the medium-load profile in the VS+ range. Renusol also offers a larger 50 x 37mm high-load rail for installations with greater span or loading demands. Your project's structural calculation determines which is required.
How is rail span and loading confirmed for my project?
Renusol provides a free PV Configurator tool that produces a full structural calculation, assembly plan, and parts list based on your roof, module, and location-specific wind/snow loads.
What module clamp type is used with this rail?
The VS+ rail pairs with Renusol's universal module clamps, which are adjustable for different PV frame heights (30–50mm) and support both middle and end clamping positions.
