Sumo Concealed EN 2–6

The Sumo Concealed EN 2–6 is a high-performance door closer designed for people who want strength, control, and a clean, modern look. Built to handle a wide range of door sizes and weights, this concealed door closer delivers smooth, quiet, and reliable closing every time. Because it is hidden inside the door or frame, it keeps interiors looking neat and uncluttered while still offering powerful performance.

Clean Design with a Hidden Advantage

One of the biggest benefits of the Sumo Concealed EN 2–6 is its concealed installation. Unlike surface-mounted door closers, this model is installed inside the door or frame, making it almost invisible once fitted. This allows architects and designers to maintain the natural beauty of the door without visible hardware interrupting the design.

Because the closer is hidden, it is also better protected from dust, impact, and tampering. This makes it a smart choice for high-traffic areas where durability and appearance both matter.

Adjustable Power: EN 2–6

The Sumo Concealed Door Closer is rated EN 2–6, which means it can handle a wide variety of doors. From lighter interior doors to heavier commercial doors, this closer can be adjusted to match the door’s size and weight.

This flexibility makes it suitable for:

• Wooden doors
• Metal doors
• Fire-rated doors
• Glass doors with proper framing

Instead of using different closers for different doors, the Sumo Concealed EN 2–6 offers one reliable solution that adapts to many applications.

Smooth and Controlled Closing

Slamming doors can cause noise, damage, and safety risks. The Sumo Concealed EN 2–6 is designed to eliminate these problems by providing smooth and controlled door movement.

The closing speed and latching action can be easily adjusted to ensure the door closes gently but securely. This controlled movement helps protect the door, hinges, and frame while also improving user comfort.

It is especially useful in places like hospitals, offices, and hotels where quiet operation is important.

Enhanced Safety and Comfort

Safety is a key reason to install a quality door closer, and the Sumo Concealed EN 2–6 performs exceptionally well in this area. By ensuring doors always return to the closed position, it helps:

• Prevent accidents caused by doors left open
• Improve fire safety by keeping fire doors closed
• Reduce drafts and heat loss
• Enhance building security

For families, employees, and visitors, this means a safer and more comfortable environment every day.

Strong and Durable Construction

The Sumo Concealed EN 2–6 is built using high-quality materials designed to withstand daily use in busy environments. Its internal components are engineered for long service life, even in high-traffic commercial settings.

Because the closer is concealed, it experiences less wear from external elements such as dust, moisture, and accidental impact. This results in fewer repairs, lower maintenance costs, and long-term reliability.

Ideal for Fire-Rated Doors

Fire safety is a major concern in modern buildings, and door closers play a critical role. The Sumo Concealed EN 2–6 is suitable for use on fire-rated doors, helping ensure they close properly in the event of a fire.

By automatically closing doors, it helps slow the spread of smoke and flames, giving occupants more time to evacuate and reducing damage to property.

Quiet Operation for Better Spaces

Noise can be distracting, especially in professional and residential environments. The Sumo Concealed EN 2–6 operates quietly, making it ideal for:

• Offices
• Conference rooms
• Hospitals and clinics
• Hotels and guest rooms
• Libraries and educational institutions

Its smooth hydraulic system ensures consistent performance without sudden movements or loud sounds.

Easy Adjustment and Installation

Despite its advanced performance, the Sumo Concealed EN 2–6 is designed for easy installation and adjustment by professionals. The power size, closing speed, and latching action can be fine-tuned to meet specific requirements.

Once installed correctly, it requires minimal maintenance, saving time and effort over the long term.

Energy Efficiency Benefits

Doors that are left open can cause energy loss by allowing heat or cool air to escape. The Sumo Concealed EN 2–6 helps improve energy efficiency by ensuring doors close automatically and seal properly.

Wide Range of Applications

The versatility of the Sumo Concealed EN 2–6 makes it suitable for many different settings, including:

• Corporate offices
• Hotels and resorts
• Hospitals and healthcare facilities
• Schools and universities
• Shopping malls and retail stores
• Luxury homes and apartments

Its combination of strength, discretion, and reliability makes it a preferred choice for modern construction and renovation projects.

Low Maintenance and Long Life
