Would you like to open your BOLD cylinder remotely? Then there is now the BOLD connect (see related products). This is a bridge that allows you to open your door remotely anytime and anywhere.
Please note : the BOLD does not close automatically. The person you let in remotely must close the cylinder again.
He/she does this by pressing the button on the inside, pulling the door closed behind him/her and then turning the knob.
Or should your door be fitted with a fixed knob so that the handle hole is not operated?
