What is the Solex Buried Door Bolt B20/8″ used for?

The Solex Buried Door Bolt B20/8″ is a recessed bolt lock that secures doors by sliding a hardened steel bolt into a recessed keeper inside the door frame or a corresponding pocket. Unlike surface bolts that mount visibly on the door face, a buried door bolt installs flush with the door edge or face so the hardware is mostly hidden, delivering a cleaner finish and enhanced resistance to forced entry. The “B20/8″ designation refers to the specific model series (B20) and the approximate bolt length of 8 inches (~200 mm), providing a solid locking reach suitable for medium‑to‑large doors.

This type of bolt is commonly used as a secondary security device alongside primary locksets (such as deadbolts or mortise locks), increasing the overall locking strength and peace of mind for property owners. Because the main bolt slides into a recessed cavity, it has fewer exposed parts that could be pried or tampered with, making it a more secure option than surface mount bolts for both residential and commercial doors.

The concealed nature also helps maintain the door’s finished look while providing a robust mechanical engagement between door and frame. Buried door bolts like this one are typically constructed from hardened steel or corrosion‑resistant materials, making them durable in everyday use and resistant to environmental wear.
