PATIKIL Round Recessed Door Lock for 35-55 mm Thick Door Panel Stainless Steel 304 Hidden Recessed Cup Door Handle Furniture Pulls Latch Knob for Privacy Pocket Door Silver

Made of 304 stainless steel, this hidden door lock is anti-rust, fade-resistant, durable, and comfortable to touch for long-lasting use.

Double-sided handle design allows the handle to be turned from inside or outside to close the door, and the rotatable handle can be hidden in the center for a simple, elegant appearance.

A small latch can be installed inside if used on an outward-opening invisible door, as the handle does not lock the door itself.

Install with the provided bolts on doors with a thickness of 35-55mm—simply turn the handle to lock or open without a key.

Widely used on doors in living rooms, bedrooms, study rooms, kitchens, bathrooms, balconies, and passages.
