Smooth operation
Very smooth closing action. I deducted one star only because the mounting template was a bit flimsy, but the spring mechanism itself is top-notch.

Great value for money
The 3-year warranty gave us confidence to try this brand. The non-positioning feature works exactly as described, allowing the door to stay open at wide angles when needed.

Perfect for heavy glass doors
Installed this on a 140kg frameless glass entrance. The hydraulic action is smooth and the closing speed is easily adjustable. Very satisfied with the build quality.

Solid upgrade from old unit
Replaced an older model with this N-818. It handles the weight much better and operates quietly. Installation instructions could be slightly clearer, but overall a great product.

Excellent durability
We use this in a high-traffic office area. After six months of constant use, it still swings perfectly without any sagging or leaking. Highly recommended for commercial use.

Professional grade hardware
As a contractor, I have installed many floor springs. This Dehuang model rivals more expensive European brands. The 160kg capacity is genuine and reliable.
Q: How do I adjust the closing speed if it is too fast?
A: There are two adjustment valves on the side of the unit. Use a small flathead screwdriver to turn them clockwise to slow down the swing or counter-clockwise to speed it up. Please refer to the manual for specific valve functions.
Q: Does the non-positioning option mean the door cannot be held open?
A: Correct. In non-positioning mode, the door will close automatically from any angle. If you need the door to stay open at specific angles, the positioning version should be selected during installation setup.
Q: What happens if the product fails within the 3-year warranty?
A: If a manufacturing defect occurs within 3 years, we provide a free replacement unit. Please contact our support team with your proof of purchase to initiate the claim.
Q: Is the installation template included in the box?
A: Yes, the package includes a paper installation template, mounting screws, and the floor spring unit to assist with precise drilling.
Q: Can this be installed on a wooden door that weighs 150kg?
A: Yes, the N-818 supports up to 160kg, making it suitable for your 150kg wooden door. Ensure the floor structure can also support this load.
