Do I need special tools for installation?

Standard tools such as a drill and a screwdriver are sufficient for installation.

Troubleshooting

Lock is difficult to turn with the key

Ensure the window is pushed fully into the closed position so there is no tension on the locking mechanism.

Restrictor cable or arm feels loose

Check that all mounting screws are fully tightened and that the base plate is flush against the frame surface.

Key is stuck in the lock

Apply slight pressure to the window while turning the key to align the internal locking pins.

  • Suitable for a wide range of frame types

Setup, Compatibility & Care

Installation requires a drill and a screwdriver. Begin by aligning the restrictor on the window frame and the opening section, ensuring the cable or arm length is set to the desired opening gap. Mark the screw holes, drill pilot holes if necessary, and secure the device using the provided screws. These locks are compatible with UPVC, aluminium, wood, and metal profiles. To maintain the device, periodically check that the screws remain tight and the locking mechanism operates freely. If you live in a coastal area, a light wipe with a silicone-based lubricant can help maintain the anti-corrosion properties of the metal.
