SMARTFY Bathroom Lock B-305 \u2014 Full Technical & Functional\u00a0<\/strong><\/h2>\n


Designed specifically as a privacy function lock<\/strong> \u2014 ideal for bathrooms, bedrooms, guest rooms, toilets, dressing rooms, and other interior doors<\/strong> where privacy (not high security) is the primary requirement.<\/p>\n

This is the type of lock often referred to as a \u201ctubular privacy lockset\u201d or \u201cbath\/bathroom lock\u201d \u2014 similar in function to ANSI\/BHMA privacy locksets used globally.<\/p>\n

\n

Construction & Materials<\/strong><\/h2>\n

Body & Components<\/strong><\/h3>\n
    \n
  • \n

    Material:<\/strong> 304 Stainless Steel<\/strong> \u2014 throughout the lock\u2019s key structural parts including the knob\/lever faces, rosettes\/escutcheons, and internal mechanisms. This grade resists rust and corrosion, making it suitable for humid environments like bathrooms. f<\/p>\n<\/li>\n

  • \n

    Finish:<\/strong> Satin Nickel<\/strong> \u2014 gives a smooth, modern aesthetic with good resistance to shows of fingerprints and wear over time.<\/p>\n<\/li>\n<\/ul>\n

    304 Stainless Steel<\/strong> is widely used in architectural hardware due to its durability and resistance to oxidation, especially in environments with moisture \u2014 such as bathrooms or coastal regions.<\/p>\n

    \n

    Door Compatibility<\/strong><\/h2>\n
      \n
    • \n

      Door Thickness:<\/strong> 40\u201345 mm<\/strong> (approximately 1\u215d\u2033\u20131\u00be\u2033), the common range for interior wood or composite doors. Many similar sets also accept slightly wider ranges with spacers\/adapters (e.g., 35\u201350 mm in other models) if needed.<\/p>\n<\/li>\n

    • \n

      Reversible:<\/strong> Works on both left-hand and right-hand doors<\/strong> (orientation doesn\u2019t matter \u2014 handle\/knob direction can be swapped).<\/p>\n<\/li>\n

    • \n

      Latch Type:<\/strong> Standard tubular latch<\/strong> (spring-loaded bolt) that retracts when the handle\/knob is turned.<\/p>\n<\/li>\n

    • \n

      Backset:<\/strong> Usually sized around 60 mm (2\u215c\u2033)<\/strong> to 70 mm (2\u00be\u2033)<\/strong> on similar units, which is the distance from the door edge to the center of the handle hole. (Exact B-305 data not published, but standard practice.)<\/p>\n<\/li>\n<\/ul>\n

      \n

      Locking Function<\/strong><\/h2>\n

      Privacy (Non-Keyed) Operation<\/strong><\/h3>\n

      This is not a keyed entry lock<\/strong>, but rather a privacy lock<\/strong>:<\/p>\n

      Inside:<\/strong><\/h4>\n

      \u2714 Turn-button or thumbturn:<\/strong><\/p>\n

        \n
      • \n

        Engage privacy mode by turning the button\/knob on the interior face.<\/p>\n<\/li>\n

      • \n

        The latch cannot be opened from the outside once privacy is engaged.<\/p>\n<\/li>\n<\/ul>\n

        Outside:<\/strong><\/h4>\n

        \u2714 Emergency unlock:<\/strong><\/p>\n

          \n
        • \n

          A small emergency slot\/hole<\/strong> on the outside plate allows unlocking with a simple tool (like a flat screwdriver or coin).<\/p>\n<\/li>\n

        • \n

          This ensures that if someone is accidentally locked inside<\/em> (e.g., child or elderly person), the door can be safely opened without breaking.<\/p>\n<\/li>\n

        • \n

          This is a standard privacy-function emergency release<\/strong> feature.<\/p>\n<\/li>\n<\/ul>\n

          This function is common on privacy locks \u2014 \u201clocked from inside with manual turn; emergency exit from outside.\u201d<\/p>\n

          \n

          5. Mechanical Details<\/strong><\/h2>\n

          Latch Assembly<\/strong><\/h3>\n
            \n
          • \n

            Latch Bolt:<\/strong> Spring-loaded, typically solid stainless steel<\/strong> or similarly durable alloy.<\/p>\n<\/li>\n

          • \n

            On many similar units, the latch projects ~12\u201316 mm<\/strong> when closed, providing secure engagement with the strike plate.<\/p>\n<\/li>\n

          • \n

            Strike Plate:<\/strong> Included, often with screws to secure into the door frame.<\/p>\n<\/li>\n<\/ul>\n

            Cycle Life & Durability<\/strong><\/h3>\n

            While specific B-305 cycle tests aren\u2019t published, privacy locks are generally tested to 100,000+ cycles<\/strong> (handle turn and latch operations) \u2014 some ANSI\/BHMA Grade 3 sets exceed 200,000 cycles<\/strong>.<\/p>\n

            Reversibility & Installation<\/strong><\/h3>\n
              \n
            • \n

              No special machining:<\/strong> Designed to fit standard bore holes<\/strong> (usually 2\u00bc\u2033 diameter), with a cross-bore and latch bore common to most interior door locksets.<\/p>\n<\/li>\n

            • \n

              Reversible latch:<\/strong> Latch can be flipped for left or right opening.<\/p>\n<\/li>\n<\/ul>\n

              \n

              6. Typical Use Cases<\/strong><\/h2>\n

              \ud83d\udccc Bathrooms & Toilets<\/strong> \u2014 privacy is essential, keyed access is unnecessary
              \ud83d\udccc Bedrooms & Guest Rooms<\/strong> \u2014 internal privacy lock
              \ud83d\udccc Office Meeting Rooms \/ Changing Rooms<\/strong> \u2014 contingent privacy requirement
              \ud83d\udccc Hotels or Guest Suites<\/strong> \u2014 simple privacy without key management<\/p>\n

              This lockset does not<\/em> provide keyed security (like front entry deadbolts) \u2014 it is intended for privacy and occupant safety<\/strong>, not burglary resistance.<\/p>\n

              \n

              7. Safety & Compliance Notes<\/strong><\/h2>\n

              \u2714 Emergency egress:<\/strong> The outside emergency release allows exit even if locked internally.
              \u2714 Non-security lock:<\/strong> Not designed for external doors or areas requiring theft protection.
              \u2714 304 Stainless Steel:<\/strong> Suitable for moist and high-usage environments \u2014 reduces corrosion and increases service life.<\/p>\n

              \n

              8. Installation Checklist<\/strong><\/h2>\n

              When installing a SMARTFY B-305<\/strong> privacy lock:<\/p>\n

              3. \n

                Align Backset:<\/strong> 60\u201370 mm typical for latch placement.<\/p>\n<\/li>\n

              4. \n

                Insert Latch:<\/strong> With bevel facing door frame.<\/p>\n<\/li>\n
