The right kit is essential for fitting your door furniture correctly. These spindles and mortice bars are suitable for door knobs and door handles. The long mortice bar is ideal for doors that are thicker than average, or for fitting a door knob to a  Rim Lock. Taylors Spindles are used for fixing a dummy door knob to a door or a cupboard.
