Up to 90kg Door Capacity

Это floor concealed door closer is designed for door panels weighing up to 90kg.

The recommended maximum door width is:

900mm

This makes it suitable for many commercial entrance, office, retail and architectural door applications.

The actual door weight and dimensions should always be confirmed before installation to ensure that the selected floor closer matches the door system.

5,000,000-Cycle Service Life

The floor closer is designed for a service life of up to:

5,000,000 opening and closing cycles

High-cycle durability is particularly important for commercial doors that may be opened hundreds or thousands of times every day.

Typical applications include:

• Office entrances
• Отели
• Торговые центры
• Retail stores
• Commercial buildings
• Стеклянные двери
• Interior swing doors

Two-Stage Adjustable Closing Speed

The closer provides two independently controlled closing stages.

Main Closing Speed: 115°–20°

The first valve controls the main closing movement of the door from approximately 115° down to 20°.

The closing speed can be adjusted according to the required door operation.

Latching Speed: 20°–0°

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

This allows the final closing action to be adjusted separately from the main closing speed.

The two-stage control helps provide smoother and more controlled door operation.

90° and 135° Hold-Open Positions

The floor closer provides hold-open positions at:

90°

и

135°

The hold-open function allows the door to remain open at the specified angle when required.

This can be useful for commercial spaces where doors need to remain open temporarily for moving goods, ventilation or high pedestrian traffic.

Maximum 135° Door Opening

The maximum door opening angle is:

135°

The wider opening angle provides greater flexibility for entrances that require a larger passage area.

The installation layout and surrounding structure should be checked before installation to ensure sufficient opening space.

Double-Action Door Operation

The closer supports double-action opening, allowing suitable doors to swing in both directions.

This makes it particularly useful for commercial and architectural door systems where two-way traffic is required.

Non-Handed Universal Design

Этот non-handed design allows the closer to be used for both left-opening and right-opening doors without requiring separate left-hand and right-hand models.

For distributors and project buyers, this helps simplify inventory management and product selection.

Horizontal Adjustment

The floor closer provides:

Horizontal Adjustment: Yes

This allows installers to make positioning adjustments during installation and alignment.

Vertical Adjustment: No

Correct floor preparation and installation height should therefore be confirmed before final installation.

Cast Iron Construction

The main body is manufactured from cast iron, providing the strength required for repeated door operation and supporting commercial door applications.

The concealed installation keeps the main mechanism below floor level, helping create a cleaner appearance compared with exposed overhead door closers.

ISO 9001 Certification

The product is supplied under an ISO 9001 quality management system, supporting standardized production and quality control requirements for B2B and project customers.
