All the digital locks displaying this logo are suitable for inside AND outside use. We recommend the SC (satin chrome) finish for the outside, as tarnishing may occur on other finishes.

The lock mechanism is sealed from water ingress and have a rubber backing plate supplied to stop wate entering the back of the unit. To ensure good external use the manufacturer advises to periodically use a non-greasy lubricant on the latchbolt face, cam, internal & external thumbturn, handle and knob.
