High quality hardware

Very impressed with the build quality. The matte black coating seems durable and scratch-resistant. It holds the heavy glass door securely and closes it gently every time.

Smooth operation

Installed this on our office entrance. The self-closing mechanism is smooth and quiet. No more slamming doors. The fact that no slot cutting was required saved us hundreds in labor costs.

Sleek and functional

This hinge completely transformed the look of our shower enclosure entrance. It feels very premium and the no-dig feature made DIY installation possible for me. Highly satisfied.

Perfect solution for retrofitting

I needed a floor spring for an existing glass door without breaking up the concrete floor. This no-dig model was exactly what I needed. The black finish looks sleek and professional. Installation took about 45 minutes.

Great look, minor adjustment needed

The hinge is very sturdy and the concealed design is beautiful. It took a little trial and error to get the closing speed just right, but once adjusted, it works perfectly. Would recommend having a second person help with alignment.

Good value for money

Does exactly what it says. Easy to install if you follow the template provided. The only reason for 4 stars instead of 5 is that the screws provided were slightly shorter than I expected, so I used my own.

5 FAQ

Q: Can this be installed on a tempered glass door that is already hung?

A: Yes, this surface-mounted design is specifically engineered for retrofitting existing doors without the need to remove the glass or cut into the floor.

Q: Is the closing speed adjustable?

A: Absolutely. There are two adjustment valves on the unit that allow you to independently control the main closing speed and the final latching speed.

Q: Does the black finish rust if used in a humid bathroom environment?

A: The finish is a corrosion-resistant powder coat applied over zinc alloy and stainless steel components, making it suitable for high-humidity indoor environments like bathrooms.

Q: What is the maximum thickness of the glass door this supports?

A: This model is designed to accommodate frameless glass doors with a thickness ranging from 8mm to 12mm (5/16" to 1/2").

Q: Can this hold the door open at 90 degrees or does it always close?

A: This is a self-closing mechanism. It will automatically close the door from any open position up to 90 degrees. It does not have a hold-open function.
