Great value for commercial use
We replaced three old springs with these GMT models. They are quiet, durable, and look professional under the glass.

Smooth operation
No slamming, no sticking. The hydraulic mechanism is top-notch. Highly recommend for frameless setups.

Good product, tricky install
The spring itself is excellent quality. Just make sure you have the right template for drilling the floor cavity. Works great now.

Solid build quality
Very sturdy construction. Installation required precise drilling, but once set, it works flawlessly. Deducted one star only because the manual could be clearer.

Perfect for heavy glass doors
Installed this on our office entrance. The 100kg capacity handles our thick glass door effortlessly. Closing speed is smooth and adjustable.

Exceeded expectations
Bought this for a boutique store door. It adds a premium feel to the entryway. Very satisfied with the purchase.
Q: What is the minimum floor depth required for installation?
A: Typically, a floor cavity depth of at least 75mm to 80mm is required to house the main body of the floor spring comfortably. Please consult the technical drawing for your specific model variant.
Q: Can I adjust the closing speed myself after installation?
A: Absolutely. There are adjustment valves accessible via the top cover that allow you to fine-tune the closing and latching speeds without removing the unit.
Q: Is this compatible with a 12mm thick frameless glass door?
A: Yes, the GMT Floor Spring series is designed to work with both framed and frameless glass doors ranging from 10mm to 12mm thickness, provided the weight does not exceed 100kg.
Q: Does this model include a hold-open function?
A: Most models in this series (like the 220B) do not have a mechanical hold-open feature; they are designed for automatic closing. Please check the specific sub-model number if hold-open is critical for your project.
Q: Is maintenance required for these springs?
A: These units are sealed and generally maintenance-free. However, we recommend checking the alignment and cleaning the surrounding area annually to ensure optimal performance.
