Schletter Solo Mounting Rail 3.55m | 120005-03550

Description

The Schletter Solo Mounting Rail is a 3.55m aluminium module-bearing profile that forms the structural backbone of Schletter Solo-based PV mounting systems. Measuring 40mm x 40mm in cross-section, it is sized to carry three standard-width modules side by side along a single rail length.

The rail combines an upper KlickNut M8 channel for clamp attachment with a lower M10 screw channel for roof hook or support fixings, giving installers a single profile that handles both module clamping and roof-side mounting hardware.

Key Features

Dual Channel Design

An upper KlickNut M8 channel accepts Rapid16 and compatible click-in clamps, while a lower M10 screw channel takes roof hooks, connectors and support hardware from the same rail body.

Three-Module Span

At 3.55m, the rail is sized to carry three modules of standard width side by side, reducing the number of rail joins needed across a typical row.

Slide-In Rail Connectors

Rails join end-to-end using a slide-in connector, allowing continuous rail runs to be built up across longer roof spans without cutting standard lengths.

High-Strength Aluminium

Manufactured from high-strength aluminium for corrosion resistance and long-term structural performance in outdoor conditions.

Compatible With Rapid16 & Classic Clamps

The KlickNut channel accepts Rapid16 click-in clamps, while the profile also supports Schletter's wider clamp and connector ecosystem.

25-Year Manufacturer Warranty

Backed by a 25-year warranty, matched to the expected service life of the solar modules it supports.

Frequently Asked Questions

How many modules can I fit on one 3.55m rail?

The rail is sized to carry three modules of standard width side by side per rail length, minimising the number of joins across a row.

Can I join two Solo rails together for a longer run?

Yes. Solo rails connect end-to-end using the Schletter Solo/Solo05 rail connector (SLT-129002-002), which slides into the rail profile to create one continuous run.

Which clamps fit this rail?

The upper KlickNut M8 channel accepts Schletter Rapid16 click-in mid and end clamps in the 30-40mm and 40-50mm ranges, giving a click-and-tighten fixing for framed modules.

What is the lower screw channel used for?

The M10 screw channel along the underside of the rail is used to fix roof hooks, support brackets and other Schletter mounting hardware directly to the rail.

What warranty does this rail carry?

Schletter backs the Solo rail with a 25-year manufacturer warranty, aligned with the typical service life of the solar modules it supports.
