20-45kg Automatic Adjustable Door Closer for Residential and ...

A 20-45KG automatic door closer is a hydraulic device designed for lighter to medium-weight interior/exterior doors (like for apartments, offices, or shops) that automatically and smoothly closes them, preventing slams and improving security/energy efficiency, featuring adjustable closing/latching speeds via separate valves for controlled movement. Key features include durable aluminum alloy construction, fire resistance (often), installation versatility, and options for hold-open, making them great for general residential and commercial use.

Door Weight: Specifically rated for doors weighing 20 to 45 kilograms (approx. 44-99 lbs).
Adjustable Speed: Two independent valves control the closing (main) and latching (final) speeds for a smooth, controlled shut.
Hydraulic System: Ensures quiet, non-slamming operation.
Material: Typically aluminum alloy for durability and corrosion resistance.
Hold-Open: Some models offer an adjustable hold-open feature (90°-180°).
Versatile Installation: Can be installed on various door types (wood, metal, fire) and sides (push/pull).
Applications: Suitable for homes, apartments, offices, schools, hotels, etc..
