120kg Door Capacity

Tento glass door floor spring is designed to support doors weighing up to:

120kg

The recommended maximum door width is:

1100mm

This capacity makes the floor spring suitable for many commercial glass door applications where a stronger concealed closing mechanism is required.

Door weight, width and installation conditions should be confirmed before installation.

Up to 5,000,000 Opening Cycles

The floor spring is designed for a service life of up to 5,000,000 opening and closing cycles.

This makes it suitable for frequently operated doors in locations such as:

• Hotely
• Nákupní centra
• Kancelářské budovy
• Retail stores
• Commercial entrances
• Interior glass door systems

Two-Stage Adjustable Closing Speed

The floor spring provides two separate closing stages for better door control.

Closing Speed: 90°–20°

The first adjustment valve controls the main door closing movement from approximately 90° to 20°.

Installers can adjust the closing speed according to the door size and operating requirements.

Latching Speed: 20°–0°

The second valve controls the final closing movement from approximately 20° to 0°.

Independent latching-speed adjustment allows smoother control during the final stage of closing.

90° and 135° Hold-Open

The floor spring provides two hold-open positions:

90° / 135°

The door can remain open at these preset angles when required, making the system convenient for locations with periods of high pedestrian traffic or goods movement.

Maximum 135° Opening

The maximum door opening angle is:

135°

This provides a wide opening range for suitable glass door installations.

The surrounding wall, glass panels and hardware layout should be checked before installation to ensure sufficient clearance.

Double-Action Opening

Tento Glass Door Floor Spring supports double-action operation, allowing a compatible glass door to open in both directions.

This is particularly useful for commercial entrances and other locations with two-way pedestrian traffic.

Non-Handed Universal Design

The non-handed design allows the floor spring to be used for both left-opening and right-opening door configurations.

This simplifies installation, product selection and stock management for distributors and glass hardware suppliers.

Horizontal Adjustment

Tento podlahový zavírač dveří supports:

Horizontal Adjustment: Yes

This allows installers to make positioning adjustments during door alignment.

Vertical Adjustment: No

Correct installation depth and floor preparation should therefore be confirmed before installation.

Cast Iron Main Body

The main body is manufactured from cast iron, providing the strength required for repeated operation and supporting doors weighing up to 120kg.

Because the main mechanism is installed below floor level, the system maintains a clean appearance around the glass door.
