Smooth operation for heavy glass
We used this for a 90kg frameless glass door in our lobby. The hydraulic action is very smooth, and the adjustable closing speed is a great feature. No leaks so far after three months.

Good quality but requires precise drilling
The build quality is excellent and feels very sturdy. Just make sure you have the right core drill bit size before starting. Once installed, it works flawlessly.

Solid performer
Does exactly what it is supposed to do. The 180-degree hold-open feature is very convenient for moving furniture in and out. Deducting one star only because the packaging was slightly damaged on arrival, though the product was fine.

Perfect replacement for old 220B unit
This floor spring was an exact fit for our office entrance. The installation instructions were clear, and the door closes smoothly without slamming. Highly recommend for commercial use.

Great value for money
Compared to other brands, this offers the same performance at a better price. The finish matches our other hardware perfectly. Installation took about an hour for a pro.

Reliable for high-traffic areas
Installed in a busy retail store entrance. It has handled thousands of cycles without any loss in tension or leaking. Very satisfied with the durability.
Q: Can I adjust the closing speed myself after installation?
A: Absolutely. There are two adjustment valves on the unit that allow you to independently control the main closing speed and the latching speed using a small screwdriver.
Q: Does this come with the mounting box and screws?
A: Yes, the package includes the floor spring body, the metal mounting box, all necessary screws, and an installation template paper.
Q: Is professional installation recommended?
A: While DIY is possible for experienced handymen, we strongly recommend professional installation as it requires precise core drilling into the floor and accurate alignment to ensure proper door function.
Q: What is the difference between the 220B and 322 models mentioned?
A: These numbers refer to the industry-standard dimensions and mounting hole patterns this spring is compatible with. This specific unit is engineered to fit all three patterns interchangeably.
Q: Is this compatible with a standard 10mm thick glass door?
A: Yes, this floor spring is designed to work with glass doors ranging from 8mm to 12mm thickness, provided the correct mounting accessories are used.
