Heavy-Duty 90/180 Degree Flip-Up Security Door Latch for Sliding & Swing Doors

Add instant privacy, childproofing, and physical break-in security to interior doors, sliding barn tracks, and entryways. Engineered for universal installation across both right-angle and flat-flush door frames, this heavy-duty 90/180 degree flip-up security door latch delivers solid, tamper-resistant locking without keys or complex deadbolts.

Cast from high-density zinc alloy with a multi-layer corrosion-resistant finish, it resists pry attacks, forced kick pressure, and humid bathroom steam without rusting or binding. Whether securing a bedroom, home office, sliding barn door, bathroom, or garden shed, this flip-up anti-theft sliding door lock bolt brings dependable security and peace of mind to any room in your home.
