Why should we use these brackets
First, ease of use. You only need a level, power driver and pencil to hang an interior door. You will only need to pick up your level once and you can throw away those shims. Quickness, we have trimmers that are averaging under 5 minutes a door. If you think you can do it the old way with shims that fast we ask you to time yourself, you might be surprised how long it actually takes you.
