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.

Worth every penny
Genuine DORMA product as described. It handles high traffic areas without any signs of wear after six months. Highly recommended for commercial applications.

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.
Q: Can the closing speed be adjusted?
A: Absolutely. The BTS80 features adjustable valves that allow you to precisely control the closing speed and latching action to suit your environment.
Q: Is this suitable for a double door setup?
A: Yes, the BTS80 can be used in double door configurations, typically installed on the active leaf while the inactive leaf uses a coordinating floor lock or pivot.
Q: What is the maximum glass thickness this supports?
A: The BTS80 is designed to accommodate glass thicknesses ranging from 8mm to 12mm, depending on the specific mounting shoe accessories used.
Q: Is this an authentic German-made product?
A: Yes, this is an original DORMA KABA product manufactured in Germany, ensuring it meets all international standards for heavy-duty door hardware.
Q: Does this come with the mounting shoes?
A: The standard package includes the floor spring body. Mounting shoes and specific glass clamps are often sold separately to allow customization for your specific glass dimensions.
