This floor spring door closer is a high-performance, heavy-duty solution engineered for framed and frameless glass doors in commercial and high-traffic buildings. Manufactured with a pressed-iron body and precision internal mechanism, it provides stable torque output and smooth door control for panels up to 110 kg and widths up to 800 mm.

Its compact structure, 305 × 146 mm cover plate, and adjustable pivot positions ensure compatibility with multiple spindle types, including C1 (DORMA), A2 (CROWN), and M3 (MAB). The sanding surface finish enhances corrosion resistance, giving the unit dependable long-term performance even under frequent use.

1. Multi-Standard Spindle Compatibility

Designed with universal spindle adapters—C1 (Dorma standard), A2 (Crown), and M3 (MAB)—the closer integrates effortlessly with mainstream top pivots and patch fittings. This increases installation flexibility and reduces the need for customized components across different project specifications.

2. Reinforced Pressed-Iron Body for Heavy Loads

The main housing is constructed from pressed iron, known for its high structural rigidity and impact resistance. This ensures stable load distribution and reliable support for doors weighing up to 110 kg, making it suitable for heavy commercial glass panels.

3. Precision Hydraulic Regulation

The internal hydraulic system delivers smooth motion control, including stable opening resistance, balanced mid-point holding force, and controlled closing speed. The adjustable valve mechanism enables installers to fine-tune speed and latch force according to environmental needs.

4. Sanding Finish for Enhanced Durability

The sanding finish on the outer cover plate provides corrosion resistance and wear protection. This reduces surface scratches and keeps the appearance clean and professional, especially in high-use environments such as retail entrances or office corridors.

5. Clear Structural Layout for Efficient Installation

Detailed dimensional indicators—such as the 250 mm mounting base length, 118 mm internal structure width, and 45 mm body height—allow installers to quickly mark and prepare accurate recessing positions. The simplified mechanical layout shortens installation time and improves alignment accuracy.

6. Optimized for 800 mm Glass Door Width

Designed specifically for mid-size commercial glass doors, the closer ensures stable torque delivery and avoids overstress on hinge points. This enhances longevity and minimizes maintenance requirements.

1. Commercial Storefront Entrances

Ideal for fashion boutiques, shopping malls, and branded retail doors requiring smooth operation and strong durability. The 110 kg support capacity ensures safe motion control even with high customer traffic.

2. Office Buildings and Business Centers

Suitable for meeting rooms, lobby entrances, and glass partition doors where professional appearance and quiet door movement contribute to a refined working environment.

3. Hospitality and Public Venues

Widely applied in hotels, lounges, restaurants, and visitor areas. The reinforced internal mechanism maintains consistent performance throughout long service cycles.

4. Institutional and High-Traffic Facilities

Recommended for airports, hospitals, schools, and public service buildings where stable opening and closing cycles are essential for both safety and accessibility.

5. Residential High-End Glass Doors

For premium home entrances, balcony doors, and interior glass dividers, the compact design and clean sanding finish help maintain visual consistency with modern home architecture.
