The Jigtech Pro Jig installation tool enables the quick installation of door handles and latches. It takes less than five minutes, because the drill holes do not have to be measured and marked out. The drilling jig can be used for doors with different thicknesses due to the self-centring clamp, and features an adjustable drill hole for the latch, which both mark out and guide drilling. The intuitive backset adjuster enables the user to easily switch between two different latch length settings.
