Exceeded expectations

Very impressed with the universal fit. We used it on a custom framed glass door, and it fit without any modifications. The buffering action is very smooth.

Silent operation

Replaced an old noisy floor spring with this one. The difference is night and day. It is almost silent when closing, which is great for our library setting.

Perfect for heavy glass doors

Installed this on our office entrance which is a heavy frameless glass door. The dual-speed buffer works flawlessly, preventing any slamming. Installation was straightforward following the template provided.

Good value for money

Solid construction and works well on aluminum alloy doors. The adjustment screws are accessible, making it easy to tune the closing speed after installation.

Great quality, tricky alignment

The build quality is excellent and feels very durable. The only reason for 4 stars is that aligning the pivot point took some patience. Once set, it operates smoothly on our wooden door.

Reliable dual positioning

We needed a spring that could hold the door open at 90 degrees for moving equipment and close automatically otherwise. This H-220B model handles both positions perfectly without slipping.

5 FAQ

Q: Can this be installed on a door that is 120kg?

A: This model is rated for doors up to 100kg. For a 120kg door, we recommend checking our heavy-duty series to ensure safety and longevity.

Q: Can I adjust the closing speed myself after installation?

A: Absolutely. There are adjustment valves on the top plate that allow you to regulate the sweeping speed and the latching speed using a standard screwdriver.

Q: Is a concrete pit required for installation?

A: Yes, since this is a concealed floor spring, a recessed pit in the floor is required to house the main body of the unit. A template is included in the box for cutting.

Q: Does the dual-positioning work on angles other than 90 and 180 degrees?

A: No, the H-220B is specifically engineered to hold positions at 90 degrees and fully open at 180 degrees. It does not hold at intermediate angles.

Q: Is this suitable for outdoor use in rainy conditions?

A: While the materials are rust-resistant, this unit is designed for indoor use or covered entryways. Direct exposure to standing water or harsh weather is not recommended.
