Heki Y Lock Skylight Security – 3D Printed Additional Security for Midi Heki Roof Hatches in RVs (17 mm Bracket)

🔒 Heki-Y-Lock – Additional Security for Midi Heki Rooflights (with 17 mm bar)

Do you know the problem?
At higher speeds, Heki rooflights with a bar closure can easily open laterally. This causes annoying wind noise, disturbance while driving, and in the worst case, can lead to damage to the rooflight.

The Heki-Y-Lock additional security was developed precisely for this:
The precisely fitting clamps reliably secure the 17 mm bar of your Midi Heki rooflight in the closed position – no play, no rattling, no more unintentional opening, even at motorway speeds.
