Pressure Lock
Pressure lock handle that improves door sound insulation by applying adjustable compression between door and frame, reducing gaps and sound leakage. Durable zinc alloy with multiple lock and latch configurations.
Product Description
SG-PL Pressure Lock Handle is designed to improve door sound insulation by applying adjustable compression between the door and frame, reducing gaps and minimizing sound leakage. Made from durable zinc alloy, it offers smooth operation, reliable locking, and long-lasting performance.
Ideal for acoustic doors, recording studios, home theatres, meeting rooms, KTV rooms, and other noise-sensitive environments. Available in left and right, with-key and no-key configurations, plus a range of latch fitting types (A, B, C, D) to suit different door assemblies.
Product Engineering Principle & Performance

Product Engineering Principle
The SG-PL improves door acoustic performance at the most common leak point — the door-to-frame gap:
- Adjustable Compression Mechanism - Pulls the door tight against the frame seal
- Durable Zinc Alloy Body - Strong, smooth, long-lasting operation
- Configurable Lock & Latch - Left/right, with/without key, latch fitting types A–D
By compressing the door against its perimeter seal, the SG-PL closes the air gaps that allow sound to leak around even well-built acoustic doors.
Why Choose SG-PL?
A high-performance acoustic door is only as good as its seal. The SG-PL applies consistent, adjustable pressure to eliminate the gaps that undermine door insulation.
Key Benefits
- Improves Door Sealing: Adjustable compression against the frame
- Reduces Sound Leakage: Closes perimeter air gaps
- Durable Zinc Alloy: Reliable locking and smooth operation
- Flexible Configurations: Left/right, with-key/no-key options
- Multiple Latch Fittings: Types A, B, C, D for different doors
- Fits Thick Doors: Up to ± 97mm door thickness
Installation Methods
SG-PL is mounted to the acoustic door leaf with its matching latch fitting installed on the frame. Select the correct handing (left/right), key option, and latch fitting type (A–D) for the door assembly, then adjust the compression to achieve a firm seal against the perimeter gasket.
Recommended Applications
SG-PL is designed for high-performance acoustic doors in:
- Professional Audio: Recording studios, broadcast rooms
- Entertainment: KTV rooms, home theatres
- Commercial: Meeting rooms, conference facilities
- Any Noise-Sensitive Environment requiring a sealed acoustic door
