90kg Heavy-Duty Door Capacity
Это heavy duty floor spring is suitable for glass doors weighing up to:
90kg
Recommended maximum door width:
850mm
It is designed for 10–12mm tempered glass and is suitable for many commercial glass door applications where controlled and reliable closing is required.
Before installation, the actual door weight, width and glass configuration should be confirmed.
Two-Stage Adjustable Closing Speed
The floor spring uses two separate valves to control the door closing action.
Main Closing Speed: 90°–20°
The first valve controls the main closing movement from approximately 90° to 20°.
Latching Speed: 20°–0°
The second valve controls the final closing movement from approximately 20° to 0°.
This allows installers to adjust the main closing speed and final latching speed independently.
90° Hold-Open Function
The standard hold-open position is:
90°
When the door reaches the designated hold-open angle, it can remain open when required.
A non-hold-open version is also available, while additional hold-open configurations can be supplied according to project requirements.
Maximum Opening Up to 130°
The maximum door opening angle is approximately:
130°
This provides a wide opening range for commercial entrances and interior glass doors.
The surrounding glass panels, wall and hardware layout should be checked before installation to ensure sufficient opening clearance.
6mm Multi-Directional Adjustment
One of the important installation advantages of this floor spring is its adjustment range.
The door position can be adjusted in multiple directions, including:
- Left and right
- Forward and backward
- Up and down
The adjustment range is up to 6mm, helping installers fine-tune door alignment during installation.
This is particularly useful when the floor box or door position requires minor correction.
Tested to 500,000 Cycles
The floor spring has passed a durability test of:
500,000 opening and closing cycles
This makes it suitable for many commercial and residential glass door applications with frequent daily operation.
Typical applications include:
- Commercial office buildings
- Offices
- Отели
- Apartments
- Retail spaces
- Interior glass doors
- Commercial glass entrances
Suitable for 10–12mm Tempered Glass
The floor spring can be used with:
10mm tempered glass
12mm tempered glass
This glass thickness range is commonly used in frameless commercial glass door systems.
Final glass dimensions, door weight and hardware configuration should be confirmed before glass processing and installation.
Non-Handed Glass Door Application
Этот подовая пружина can be used in common glass door configurations where flexible door alignment and double-action operation are required.
Its concealed floor installation helps maintain a clean appearance around the glass entrance while keeping the main closing mechanism below floor level.
