A flush lock is a type of door hardware designed to secure doors while maintaining a sleek, recessed appearance. Similar to flush bolts, flush locks are mounted within the door’s edge or face, ensuring that the locking mechanism sits flush with the door surface, minimizing protrusions and enhancing the aesthetic appeal.

Where It's Used:

• Sliding Doors: Flush locks are commonly used on sliding doors (like pocket or barn doors) where standard doorknobs would be impractical.
• Bi-fold or Closet Doors: Often installed on bi-fold or closet doors for a clean appearance and easy locking mechanism.
• Glass or Aluminum Doors: Frequently used in modern glass or aluminum framed doors in commercial buildings to maintain a minimalist look.
• French and Double Doors: In some cases, flush locks are used on French or double doors to provide a lock while keeping the hardware discreet.

Flush locks are ideal for spaces where door hardware needs to be both functional and low-profile, preserving the overall clean lines of modern architecture.
