Product Description

Ozone Floor Hinge OFH-6600 is a single cylinder concealed floor spring for glass and wooden doors — carrying the door’s weight and controlling its closing action from a recess in the floor.

A floor spring does two jobs at once, and that is why frameless glass entrances use them rather than overhead closers. It carries the entire weight of the door on its spindle, and it controls the closing action hydraulically. There are no hinges and no visible closer — the mechanism sits in a recess in the floor, hidden under a cover plate.

That is what makes a frameless glass door look the way it does. Nothing interrupts the glass except the patch fittings, because everything mechanical is underfoot. The trade-off is that the floor has to be prepared before the door goes in — a recess formed in the slab, level and drained. Retrofitting one into a finished floor means breaking it up.

Key Features

• Carries the door weight and controls closing in a single concealed unit
• Completely hidden: Nothing visible except the cover plate underfoot
• Pairs with Ozone patch fittings: The OPF-3 bottom patch sits directly onto the spindle
• Single cylinder design: A more compact and economical unit, well suited to standard door weights and normal traffic
• Smaller floor recess than a double-cylinder unit, which can matter where slab depth is limited

Floor Preparation — Plan This Early

• The floor recess must be formed before the door is installed. Retrofitting a floor spring into a finished floor means breaking up the slab
• Get the door weight right. Glass is heavy — roughly 30 kg per square metre at 12 mm. An under-rated spring sags and the door drops out of alignment
• The recess must be level and drainable. Water sitting in a floor spring pocket will shorten its life considerably
• Order the patch fittings to match. The OPF-3 bottom patch sits onto this spindle — buy them as a set
• Consider access for adjustment. Closing speed valves are reached through the cover plate, so it must remain accessible after the floor is finished

FAQs

1) What does a floor spring actually do?

Two things. It carries the entire weight of the door on its spindle, and it controls the closing action hydraulically. On a frameless glass door there are no hinges and no overhead closer, so the floor spring does both jobs.

2) Why use a floor spring instead of an overhead closer?

Appearance and load. A floor spring is completely hidden underfoot, so nothing interrupts the glass. It also carries the door weight, which an overhead closer does not. The cost is that the floor must be prepared in advance.

3) Can it be fitted to an existing finished floor?

Only by breaking up the slab to form the recess. If the floor is already finished and cannot be cut, use an overhead glass door closer such as the NSK series with its mounting plate instead.

4) What door weight will it take?

Confirm the rating against your door before ordering. As a guide, 12 mm toughened glass weighs roughly 30 kg per square metre — calculate the actual figure rather than estimating, because an under-rated spring will sag.

5) What else do I need for a complete door?

A top patch, bottom patch (OPF-3), top pivot, patch lock and handles. The bottom patch sits directly onto this floor spring’s spindle, so order them together and in matching finish.
