Height: 114 mm Width: 52 mm features: The Latch pull with cylinder Illuminator will ensure there is no more fumbling around in the dark to find the keyhole, as it lights up the rim cylinder as you approach the door, so you can pinpoint exactly where the keyhole is. The built in sensor only works in the dark and is triggered from about 5 metres away. The unit fits over the existing rim cylinder, so it is easy to retrofit the Illuminated Cylinder Pull to timber doors.
