Sleek design and reliable

Looks professional under our aluminum framed door. The silver finish matches our hardware perfectly. No leaks or issues after six months of daily use.

Perfect for heavy glass doors

Installed this on a 85kg frameless glass door in our office lobby. The 90-degree hold-open feature works flawlessly, and the closing action is smooth and quiet. Very impressed with the build quality of the aluminum alloy.

Does exactly what it says

Universal type as advertised. Worked on our retrofit project without needing major modifications to the floor pit. The 90kg capacity gives us plenty of safety margin.

Smooth operation

Very happy with this purchase. The door closes gently but firmly every time. The positioning feature is helpful for moving furniture or large items through the doorway.

Solid unit, installation requires precision

The spring itself is very robust and handles our heavy wooden door easily. Deducting one star because the template for drilling needs to be measured very precisely, but once installed, it works great.

Great value for commercial use

We replaced three old units with these GBDWN springs. They handle high traffic well and the adjustable speed valves make it easy to customize the closing rate for different door weights.

5 FAQ

Q: Can I adjust the closing speed myself after installation?

A: Yes, there are adjustment valves on the top of the unit that allow you to regulate the closing and latching speeds using a standard screwdriver.

Q: Is this suitable for outdoor entrance doors exposed to rain?

A: While the aluminum alloy is corrosion-resistant, we recommend installing a protective cover or ensuring the drainage system is effective if the unit is directly exposed to heavy rainfall.

Q: Is there a back-check function to prevent the door from slamming open?

A: The H-220A model primarily features adjustable closing and latching speeds with a 90-degree hold-open. For specific back-check requirements on very high-wind areas, please consult our technical team for alternative models.

Q: What is the minimum floor pit depth required for installation?

A: We recommend a floor pit depth of at least 75mm to accommodate the H-220A body comfortably, allowing space for concrete grouting around the unit.

Q: Can this floor spring be used for a double door setup?

A: Yes, you can use two H-220A units for a double door setup, provided each door leaf weighs less than 90KG. Ensure they are synchronized during installation.
