Identifying Parts of Your Door Locks [infographic]

Whether you are a new homeowner or have been browsing online for an upgraded lock, you will quickly discover that there is a wealth of vocabulary to learn when it comes to something so seemingly simple as your door lock. Here at Coastal Contract Hardware, we work with locks frequently and would like to help some of our customers when it comes to the labeling and identification of the working and stationary portions of their door locks. Here are a few that you can expect to find with most any lock:

  • Strike Plate- The strike plate is separate from the lock, but also important to security. The strike plate is the portion of a lock that is secured to the door jamb and accepts the lock bolt.
  • Spindle- Located in the middle of any doorknob’s inner workings is where the spindle, a short bar, operates the two handles and holds the knobs together.

  • Trim- Attached under the doorknob, this sometimes decorative plate is also called a rose.
  • Deadbolt- Strong and secure, the deadbolt is a lock that is key operated and often above the doorknob.
  • Chassis- The chassis is the inner portion of the locking mechanism and determines if your knob is a key, bedroom or bathroom knob or closet knob.
  • Escutcheon- This is a plate (may or may not be decorative) that surrounds a lock or keyhole and prevents drilling or scratches.
  • Backplate- The metal plate is there to protect your lock from wear that comes with frequent use.
  • Bore Holes- These holes are drilled purposely for door hardware installation and can be standard or custom.
