Dormakaba QDB200, QDB284 Operating instructions

  • Hello! I've reviewed the installation instructions for the dormakaba QDB200 series deadbolt, specifically model QDB284. This document provides detailed steps for installing the deadbolt, including the use of a drilling template and guidance for mounting various components such as the adapter plates, latch, and strike plate. I'm here to help answer any questions you might have about the installation process or the device itself.
  • What tools are recommended for installation?
    What is the correct orientation for the deadbolt latch?
    What is the drilling depth for hole A?
