Perfect for heavy glass

We needed something reliable for a thick glass partition. This floor spring provides excellent stability and the hydraulic mechanism is very quiet.

Solid performer

Very robust hinge. Installation required precise drilling, but once set up, it works flawlessly. Deducting one star only because the installation manual could be more detailed.

Great durability

Installed in a busy retail store. It has held up perfectly under constant use. The only downside is the price, but you get what you pay for in terms of longevity.

Industrial grade quality

Installed this on a heavy entrance glass door for our office lobby. The build quality is exceptional, and the closing action is smooth and controlled even with the 300kg load.
