Self-locking drive gear

Put a stop to burglars

Put a stop to burglars

Prevent intruders from gaining entry by manually shifting the cam! Thanks to MACO’s self-locking drive gear, this method is now a thing of the past. The secret behind this unique solution is the automatic anchorage of the security cam, which cannot be shifted to unbolt the window even if a force of 300 kg is applied in an attempt to gain access. (Image left) The self-locking drive gear therefore considerably increases the basic security of the window in the locked position, even without a lockable window handle, which would otherwise be used to prevent the cam from being shifted. If force is applied without self-locking drive gear, the handle turns upward. (Image on the right)

The self-locking drive gear is quick to install, and cost-effective and easy to retrofit.
