Product Information

Product Overview

The Ozone Floor Spring FS-8400 is a double-cylinder concealed floor spring for frameless glass and wooden doors. It carries doors up to 80 kg and 950 mm wide, controls closing hydraulically, and includes a standard 90° hold-open. The satin stainless steel cover plate is all that shows above the floor.

Two hydraulic cylinders share the closing load, which gives smoother control and longer life on heavier or busier doors than a single-cylinder unit. That makes it the right choice for main entrances, showrooms and offices with steady foot traffic. The Ozone OPF-3 bottom patch sits directly on its spindle.

Key Features

  • Double-cylinder hydraulics for smooth, durable closing
  • Door weight up to 80 kg
  • Door width up to 950 mm
  • 90° hold-open as standard
  • Satin stainless steel cover plate
  • Fully concealed in the floor

Ideal For

  • Busy shop and showroom entrances
  • Office main doors
  • Heavy frameless glass doors

Installation Guide

  1. Plan the floor recess before the floor is finished.
  2. Keep the recess level and drained.
  3. Check that the door's weight and width are within 80 kg and 950 mm.
  4. Install the spring exactly below the top pivot.
  5. Fit the OPF-3 bottom patch, hang the door and adjust the closing speed and latch.

Care & Maintenance

  • Keep the cover plate free of water and grit.
  • Readjust the speed valves through the cover plate if the closing changes.

Good to Know

  • The patch fittings, lock and handles are sold separately.
