Reliable and durable
We installed these in a high-traffic retail store six months ago, and they are still performing perfectly. The 90-degree stop is very precise.

Highly recommended
Excellent hardware. The mechanism feels robust and provides a gentle close every time. No slamming noises anymore in our hallway.

Perfect for my office glass door
This floor spring works exactly as described. Installation was straightforward with the provided template, and the closing action is smooth and quiet. Great value for the price.

Solid build quality
Very sturdy construction. It handles our heavy wooden door without any issues. I deducted one star only because the instructions could be slightly more detailed for beginners.

Great replacement part
Replaced an old broken spring with this HUANG KONG model. It fits standard cutouts and the adjustment screws make it easy to tune the closing speed.

Good product for the cost
Does the job well. The finish looks professional on our frameless glass entrance. Shipping was fast and packaging protected the item well.
Q: What is the maximum door thickness this supports?
A: This model is designed primarily for frameless glass doors typically ranging from 10mm to 12mm, but it can accommodate wood or iron doors up to 45mm thick with the correct adapter fittings.
Q: Is this suitable for a double glass door setup?
A: Yes, but you will need to purchase two units, one for each door leaf, to ensure proper operation and alignment.
Q: How do I adjust the closing speed?
A: There are two adjustment valves on the top cover. Use a small flathead screwdriver to turn them clockwise to slow down or counter-clockwise to speed up the closing action.
Q: Does it have a hold-open feature?
A: No, the H220B model is a standard closing spring with a 90-degree stop. It does not have a hydraulic hold-open function at intermediate angles.
Q: Can this be installed on a concrete floor?
A: Absolutely. The package includes anchors suitable for concrete installation. You will just need a hammer drill to create the mounting holes.
