2 Pcs Automatic Sensor Door Closer with Drawstring - Kelamayi - Black

This product listing is for a pack of 2 automatic door closers.

The steel wire rope has a strong 800G pull force, designed for reliable rebound.

The 3M adhesive is designed to provide good firmness without damaging walls or door surfaces under normal use and removal conditions. However, always test on an inconspicuous area first if concerned.

Yes, it can be installed on glass doors provided the surface is clean, smooth, and free of any coatings that would prevent adhesion. Ensure firm pressure during installation.

While it is durable and resistant to high temperatures, it is primarily designed for interior doors. Prolonged exposure to harsh weather conditions might affect its longevity and adhesive performance.

This particular model does not feature adjustable speed settings. The closing action is determined by the spring mechanism within the device.

It is generally not recommended for very heavy, unbalanced, or exterior storm doors that require significant force to close or have specialized closing mechanisms.

Check if the hook is securely attached to the door and the closer mechanism is firmly attached to the frame. Ensure the steel wire rope is not tangled or obstructed. Verify that the door is not sticking or rubbing against the frame.

This model does not have adjustable speed settings. For doors that are too heavy or require a gentler close, consider if this device is the appropriate fit or if the door requires additional balancing.

Ensure the installation surfaces were thoroughly cleaned and dried before application. Re-apply the adhesive after cleaning the surfaces with an appropriate cleaner (e.g., isopropyl alcohol) and allow the adhesive to cure for the full 24 hours.

While designed for durability, excessive force or constant strain beyond its rated capacity may affect performance over time. Ensure the door is not being forced open or held open against the closer's pull.
