Perfect for heavy commercial doors

We installed this on our main warehouse entrance which sees a lot of traffic. The 160kg capacity is no joke; it handles the heavy steel door effortlessly. The rebound feature works smoothly even when there are obstacles.

Solid performer

Does exactly what it says. The obstacle rebound is sensitive enough to prevent pinching but strong enough to close the door firmly. Only minor issue was the instruction manual could be more detailed.

Exceeded expectations for outdoor use

We were worried about water damage since it's an outdoor install, but the waterproofing is excellent. No rust or corrosion after six months of rain and snow. Highly recommend for exterior applications.

Best floor spring we've used

We manage several properties and have tried many brands. The Dehuang DSW3A is by far the smoothest operating unit. The adjustable speed settings allow us to customize it for different user groups.

Reliable automatic closing

Bought this for a double-door setup in a windy area. The combined direction feature ensures both leaves close properly without slamming. Very satisfied with the German engineering standards mentioned.

Great quality, installation requires care

The build quality feels very premium and robust. It survived a harsh winter outdoors without freezing up. Installation took a bit longer than expected as the floor cavity needs to be precise, but the result is worth it.

5 FAQ

Q: What tools are needed for installation?

A: You will need a core drill for the main body, a chisel for the cover plate recess, a level, and standard wrenches. A template is included in the box to guide hole placement.

Q: Can this be used for a fire-rated door?

A: This model is designed for general heavy-duty use. For fire-rated doors, please consult local fire safety regulations and ensure this specific unit meets the required fire certification for your region.

Q: Is the opening speed adjustable?

A: Yes, the DSW3A features independent valves to adjust the opening speed and closing latching speed to suit your specific door weight and environment.

Q: Does this work in temperatures below freezing?

A: Absolutely. The hydraulic fluid used is rated for low temperatures, and the housing is designed to prevent ice buildup, making it suitable for cold climates.

Q: Can this be installed on a wooden floor or does it require concrete?

A: While it can be mounted on reinforced wood, we strongly recommend installation in a concrete floor for maximum stability and to handle the full 160kg load safely over time.
