Drill Free Blinds: Kepler Adhesive and Taurus Pressure-Mounted Blinds for Installation Without Construction Work
When an installation doesn’t allow for drilling into the frame, glass, or side panels, working with a drill free blinds makes all the difference between a makeshift solution and a clean, controlled installation. At Rutperfil, we address this scenario with two different systems: Kepler, designed for adhesive mounting on windows or doors, and Taurus, designed for installation between walls using the pressure-mounted mechanism.
1. Kepler System: Adhesive Engineering on Profiles
The Kepler System doesn’t use simple double-sided tape; it employs an industrial-grade adhesive polymer designed to withstand the thermal expansion of the window and the continuous tension of the chain drive.
Optimal Surfaces: Structural performance on glass and aluminum. Excellent performance on PVC and lacquered surfaces in good condition (not suitable for untreated wood or rough/dirty surfaces).
Versatile Mounting: Its extruded design allows for installation on the frame, glazing bead, or directly on the glass, guiding the blind along the window (perfect for tilt-and-turn windows).
Curing Protocol: To ensure strength, installation requires cleaning the surface with isopropyl alcohol, positioning the roller box, applying even pressure, and respecting the 72-hour chemical curing period before subjecting it to any load.
⚠️ Critical Installation Specifications (Kepler):
Total Width: The ordered measurement includes mechanisms and guides. The visible fabric will be 5 cm narrower.
Total Height: The system is 9 cm taller than the visible fabric.
Support: A minimum flat surface of 1.5 cm between the handle and the glass is required for structural adhesion.

2. Taurus System: Mechanical Expansion Between Walls
When the goal isn’t to cover the window sash, but rather to fill an entire architectural opening (such as the space between two columns or the interior of a window frame), adhesives give way to pure physics.
The Taurus System is designed to anchor exclusively between walls using a rotating pressure mechanism.
Tool-free installation: The leveled blind is placed inside the opening, and the end mechanisms are rotated. This expands the side stops, generating sufficient mechanical pressure to lock the system against the walls, keeping it completely stable and aligned.
Environmental protection: An impeccable solution for rental properties, bathroom tiles, or openings where drilling is prohibited. It does not require adhesive for the window frame.
⚠️ Critical Installation Specifications (Taurus):
Width Calculation: The requested measurement must be the exact distance of the interior opening. As with Kepler, this width includes the mechanism, so the fabric will be approximately 5 cm below the total width ordered.

Kepler or Taurus?
Both systems can be ordered from the factory in three formats depending on your business’s service requirements: as a kit (individual components), as a bare system (assembled without fabric), or as a finished product with fabric. To make the right choice on site:
- Choose KEPLER if: You need the blind to move in unison with the window/door, you have smooth surfaces (glass/aluminium/PVC) and there is space for the box without interfering with the handle.
- Choose TAURUS if: You have a recess or opening between walls, you do not want to alter the window, or the framing is irregular/untreated wood.
Here is the table translated into English, maintaining the technical and direct tone for a B2B context:
Technical Summary for Specification
| System | Mounting Method | Ideal Placement | Key Strength | Technical Limitation |
| Kepler | Chemical (High-performance adhesive) | Window frame, glazing bead, or glass. | Total integration into the sash. Fast installation, guided directly on the window. | Not suitable for untreated wood. The cassette (4.8 cm projection) may interfere with inward wall-facing openings. |
| Taurus | Physical (Tension / Pressure mechanism) | Exclusive for window recesses / between walls. | Clean mechanical installation with no glues or drilling on delicate surfaces. | Strictly designed to work between parallel walls; impossible to mount on the front frame. |
Eliminating the drill from the equation doesn’t mean reducing quality; it means evolving the hardware so you save time and avoid problems.
