SL Rack Mounting Rail RAIL 40 (4750 mm)

📏 Main Parameters

📐 Length: 4,750 mm

🧱 Profile: 40 x 40 mm square section

🪶 Material: Aluminum (natural or black anodized) – lightweight and corrosion-resistant

⚖️ Weight

A single rail weighs approximately 3.94 kg – this is a relatively lightweight profile, simplifying transportation and installation without adding unnecessary weight to the roof.

🔩 Design and Compatibility

The RAIL 40 has a deep upper channel, suitable for mounting modular terminals with a 30–50 mm frame.

The lower channel is optimized for installing brackets/crocodile clips and is compatible with all SL Rack system mounting elements (requiring appropriate brackets and holders).

The profile is compatible with the SL Rack system itself and can be combined with most standard modular fastening solutions on the market.

🛠️ Strength and Application

Although the manufacturer does not specify specific static load or permissible deflection figures for RAIL 40 in public specifications, SL Rack aluminum profiles are traditionally designed to support panels under standard snow and wind loads on residential and commercial roofs (exact values ​​are determined by the installation project and installation conditions; see the manufacturer's static data sheet for calculations).

RAIL 40 provides sufficient rigidity with low weight, suitable for both pitched and flat roofs.
