9/10 Security Rating

The Yale PM444 Mortice Door Bolt is a concealed security solution designed specifically for timber doors. Commonly known as a rack bolt, this device is morticed into the door leaf to provide an additional point of resistance against forced entry. It is typically installed in pairs, positioned at the top and bottom of the door, to complement the primary locking system and ensure the door remains secure across its full height.

The bolt functions via a rack and pinion mechanism, which is activated by inserting a standard splined rack bolt key into the keyhole on the face of the door. This mechanism drives the bolt forward into a strike plate mounted on the door frame. Because the key is removable and the bolt is hidden within the door, it provides a clean, unobtrusive security upgrade that is ideal for both domestic and commercial settings.

This product is suitable for new door installations or as a direct replacement for existing rack bolts of similar dimensions. Its simple cylindrical body allows for easy preparation using standard drill bits, making it a practical choice for improving perimeter security on front and rear external doors.

  • Provides secondary security without visible external hardware
  • Hardened steel bolt for resistance to physical attack
  • Universal handed design for versatile installation
  • Operates smoothly with standard star-shaped keys
