Tips

For best results, ensure your door is properly aligned and the mortise lock is centered before installing the knob set. Use a soft cloth with mild detergent to clean the stainless steel surface; avoid abrasive pads that could scratch the brushed finish. If your door is at the thicker end of the range, verify that the included screws are long enough or source longer through-bolts for a secure fit.
