Overview

The Ningbo Dimon Concealed Round Flush Ring Pull Door Lock is an ultra-low-profile architectural lockset engineered for concealed flush doors, sliding pocket doors, secret bookcase doors, and modern minimalist wooden partitions. Designed to sit completely flush with the door face, it features an integrated flip-out rotating pull ring that folds neatly away when not in use, creating seamless, obstruction-free wall and door lines. Available in both Keyed Entry (with precision cylinder and computer keys) and Keyless Privacy / Passage configurations, this lock combines a heavy-duty brass deadbolt with a solid 304 stainless steel recessed escutcheon to deliver discreet security and effortless operation.

Key Features

• Ultra-Flush Recessed Architectural Profile: Circular recessed escutcheon sits virtually flat against the door panel, allowing pocket doors to slide completely into wall cavities without clearance interference.
• Retractable Flip-Out Pull Ring: Spring-loaded rotating pull lever lifts easily from the recessed cup to slide or swing the door, then folds flush into the escutcheon when released.
• Dual Locking Functionality:
  • Keyed Security Lock: Equipped with a solid brass computer cylinder and 3 keys for secure locking from the exterior.
  • Privacy / Keyless Lock: Equipped with an ergonomic thumbturn for bathrooms, powder rooms, and private bedrooms.
• Heavy-Duty Solid Brass Deadbolt: Heavy-gauge tubular deadbolt latch resists prying, jimmying, and forced entry while providing smooth, positive latching.
• Premium 304 Stainless Steel Construction: High-density corrosion-resistant AISI 304 stainless steel face and zinc alloy interior chassis resist wear, tarnishing, and corrosion.
• Contemporary Designer Finishes: Available in Brushed Satin Silver, Electrostatic Matte Black, Architectural Gunmetal Gray, Antique Bronze, and Titanium Gold.
