This floor spring door closer is a robust, precision-engineered solution designed for both framed and frameless glass doors. Manufactured with a pressed-iron body and finished with a durable sanding surface, it delivers stable mechanical strength and long-term corrosion resistance.

The compact internal structure, featuring a 305 × 146 mm cover plate and a 45 mm body height, ensures a clean installation while maintaining compatibility with a wide range of door systems. The closer supports glass door widths up to 800 mm and a maximum load capacity of 110 kg, making it suitable for high-traffic commercial environments.

With multiple interchangeable spindles—C1 (DORMA standard), A2 (CROWN), and M3 (MAB)—the unit integrates seamlessly with global top pivot standards, allowing installers to adapt the closer to diverse project requirements with ease. Its refined hydraulic regulation provides smooth, stable closing motion, ensuring safety, quiet operation, and long-term reliability.

1. Universal Spindle System for Broad Compatibility

The floor spring includes interchangeable spindles compatible with C1 (DORMA), A2 (CROWN), and M3 (MAB) systems. This allows the product to adapt to various door patch fittings and top pivots without modification, reducing installation complexity and improving cross-brand compatibility.

2. High Structural Strength with Pressed-Iron Body

The heavy-duty pressed-iron housing delivers exceptional rigidity and impact resistance, making the closer ideal for doors weighing up to 110 kg. This ensures stable torque transmission and long-term durability, even in frequently used commercial entrances.

3. Precision-Controlled Hydraulic Performance

An engineered hydraulic system provides smooth door operation with adjustable closing speed and latching force. The mechanism ensures controlled motion throughout the entire swing cycle, reducing noise and preventing abrupt slamming in high-traffic environments.

4. Sanding Finish for Enhanced Wear Protection

The sanding surface finish improves corrosion resistance and minimizes visible scratches. This keeps the product looking clean and professional over years of use, particularly in environments such as retail stores, office buildings, and hospitality facilities.

5. Optimized Dimensions for Easy Installation

With a body length of 268–280 mm, width of 96–118 mm, and height of 45–46 mm, installers can fit the closer into standard floor recesses without customization. The clear dimensional guides on the technical diagram help achieve precise placement and alignment.

6. Engineered for 800 mm Door Width Applications

The floor spring is specifically optimized for glass doors up to 800 mm in width, ensuring balanced force distribution and smooth motion control. This prevents unnecessary stress on fittings and extends the overall service life of the door system.

1. Retail and Commercial Storefronts

Ideal for boutique entrances, mall stores, and shopfront glass doors. The heavy-duty construction and smooth closing motion handle constant customer traffic with consistent performance.

2. Office Buildings and Corporate Interiors
