Tubular Knob Lock

Boluosi Tubular Knob Lock – this one uses a stable three-rod structure, so day-to-day door security is pretty reliable. It works with different door thicknesses, which makes it a good fit for homes, apartments, and light commercial use.
The latch is adjustable at 60 or 70mm, so installation is more flexible and you don't have to mess around with complicated adjustments. The drilling holes are kept small, which means less damage to the door surface and no major modifications. That makes the whole install faster and cleaner.
Compatibility is strong – in many cases, it fits right into existing door holes without extra work. The structure makes it easy for you to install and quickly take it apart when needed. Replacement parts aren't hard to find either, so maintenance is more efficient and long-term repair costs stay lower.
