Highly recommended for frameless glass
Finding a floor spring that can handle 110kg for frameless glass is tough. This GMT model exceeds expectations. The hydraulic mechanism is quiet and efficient.

Solid upgrade from old model
Replaced an older floor spring with this H+ version. The engineering upgrade is noticeable; the motion is much smoother. Installation required precise drilling, so professional help is recommended.

Genuine GMT quality
Verified the authenticity code on the packaging, and it is indeed genuine. The finish matches our office hardware perfectly. It handles the weight of our large lobby door with ease.

Great value for commercial use
Bought five units for our new branch. They are robust and reliable. One unit needed a slight adjustment out of the box, but customer support guided me through it quickly.

Perfect for heavy glass doors
Installed this on a 10mm tempered glass door weighing about 95kg. The two-stage speed control works flawlessly, ensuring the door closes gently without slamming. Very impressed with the build quality.

Smooth operation
We use this in a high-traffic retail store. After three months of constant use, it still operates as smoothly as day one. The adjustable closing speed is a great feature for different times of the day.
Q: What is the difference between this and the standard GMT floor spring?
A: The H+ Engineering Upgrade offers enhanced durability, a refined hydraulic system for smoother operation under heavy loads, and improved corrosion resistance compared to the standard series.
Q: Can I adjust the closing speed myself?
A: Absolutely. The H+ Engineering Upgrade features external adjustment valves that allow you to fine-tune the two-stage closing speed using a standard screwdriver.
Q: Does this come with the installation template?
A: Yes, the package includes a precise paper installation template, mounting screws, and an instruction manual to ensure correct positioning.
Q: Is professional installation required?
A: While not strictly mandatory, we highly recommend professional installation for frameless glass doors to ensure the core hole is drilled accurately and the structural integrity of the glass is maintained.
Q: Is this suitable for a 12mm thick glass door?
A: Yes, provided the total weight of the door does not exceed 110KG. The thickness alone does not determine compatibility; the total mass is the critical factor.
