It offers a simple and economical door closing solution that requires no electricity, heat, or energy.

Product Features and Material Details

The YM729 model stands out as a simple, durable, and economical closing solution for light doors:

Mechanism Type: Mechanical Door Closer Spring (Traditional Door Closer Spring).

Function: The spring stretches when the door is opened and uses this tension to push the door back. The closing speed cannot be adjusted; the spring force is fixed. It is mounted next to the door handle or at the top of the door.

Capacity: 15 kg – 30 kg.

Suitable Doors: Specifically designed for low-weight doors such as very light interior doors, wooden partition doors, light storage lids, or screen doors. It may be insufficient for standard entrance doors.

Material: High-Strength Spring Steel and Steel Body/Arms.

Spring: Hardened steel spring (spring steel) resistant to long-term use and repeated tensioning.

Body/Arm: Steel or reinforced metal alloys are used for easy installation and robustness.

Coating: Usually coated with zinc plating or electrostatic paint to prevent corrosion.

The Yuma YM729 is used in light doors requiring an economical and basic automatic closing function:

Light Interior Doors: Light partition doors in offices or homes.

Service Doors: Light service doors used by waiters in places like restaurants, cafes, or kitchens.

Screen and Net Doors: Since the spring force is not adjustable, it is an economical solution for controlled closing in such very light and simple doors.
