As a professional, you know that not all walls are straight. Bay windows, columns, fitting rooms, or room dividers in hospitals often require curved rails like Double T Rail.

Traditionally, this meant ordering a pre-curved rail from the factory (with the risk of measurement errors) or hauling a heavy bending machine to the job site.

At Rutperfil, we have a more agile solution: The Double T Rail System.

What makes the Double T Rail unique?

The key lies in its design. Unlike a standard rigid rail, the aluminum profile 920052 features a specific “Double T” structure (7x15mm) that allows it to be curved manually right on the job site.

  • No Tools Required: You can shape it with your hands (or by using your knee for leverage) to follow the exact contour of the wall or ceiling.

  • No Channel Deformation: Its engineering ensures that, when bent, the channel where the gliders run does not close or warp, guaranteeing the curtain slides smoothly.

System Components

The system is simple yet robust, designed for rapid installation:

  • Aluminum Profile (920052): Supplied in 5m bars, ready to cut and bend. White finish.

  • Special Gliders:

    • Double T Glider (922011): Designed specifically for this profile, combining metal and plastic for strength and silence.

    • Extra Glider (922060): Additional option (12x25mm).

  • Versatile Fixing:

    • Ceiling Bracket (923042): Metallic, discreet, and strong.

    • Universal Bracket (923031): For greater mounting flexibility.

  • Finishes: End caps and metal stops for a secure finish to the installation.

Where to install the Double T Rail?

This system is the perfect “go-to” solution to keep in your van. It is ideal for:

  • Arched windows or bay windows in residential homes.

  • Bed separation in hospitals or clinics.

  • Fitting rooms in clothing stores.

  • Ceiling decoration with organic shapes.

  • Vehicles: Caravans, boats, or trucks where space is irregular.
