ECO Newton TS-41 K Door closer
Wide range of door closing devices to suit all possible applications
The ECO Newton TS-41 K has been designed to deliver maximum performance within a compact footprint. Below is a summary of its most important technical features:
These specifications ensure smooth, controlled door movement while meeting regulatory requirements for commercial and public buildings.

What truly sets the ECO Newton TS-41 K apart is its suite of proprietary ECO technologies. Each feature has been designed to improve performance, simplify installation, and enhance long-term value.
The ECO Newton closer portfolio covers all door dimensions using just two basic closer units. This approach simplifies planning, specification, and inventory management while ensuring consistent performance across an entire building.
The door closer and slide rail form a single unit constructed from aluminium and stainless steel. This integrated design improves durability, structural integrity, and visual harmony.
The stainless steel cover is mounted using the power of spring steel, snapping securely into place. It conceals all adjustment elements, protecting them against unauthorized access while delivering a clean, architectural finish.
All parameters of the closing process can be adjusted with one standard Allen key. The high-precision valve system ensures accurate, long-lasting settings without the risk of accidental changes.
For projects with elevated design requirements, an optional stainless steel cover is available. When paired with a matching stainless steel lever arm, it creates a refined, uniform appearance that complements modern interiors.
When the door is closed, the slide rail and door closer sit flush with one another. Carefully matched colours—down to the slide rail end caps—ensure a cohesive and discreet visual result.
ECO vario allows the use of all slide rail door closers and enables combinations with different door leaf widths. This flexibility ensures optimum value for money for every individual door situation.

Thanks to its versatility and refined appearance, the ECO Newton TS-41 K is suitable for a wide range of applications:
In many of these settings, the ECO Newton TS-41 K is specified alongside complementary door hardware solutions. Learn more about integrated systems on our dedicated door hardware solutions page.
At the heart of the ECO Newton TS-41 K is a hydraulic control system that ensures smooth, controlled door movement from any opening angle up to 180°. The adjustable closing and latching speeds allow installers to fine-tune performance based on door weight, usage frequency, and user needs.
The fixed back-check function helps protect walls and door frames by slowing the door during rapid opening. This combination of control and protection makes the ECO Newton TS-41 K ideal for busy environments where durability and user comfort are equally important.
Installing the ECO Newton TS-41 K is straightforward thanks to its universal design and comprehensive installation accessories. The same closer can be used for DIN left and DIN right applications, reducing complexity on site.
The included paper template ensures precise positioning, while the low mounting height makes the closer suitable for narrow door profiles. Once installed, adjustments can be carried out quickly using a single Allen key.
Maintenance requirements are minimal. The stainless steel cover protects internal components from dust, impact, and tampering, ensuring long-term reliability and consistent performance over time.
The ECO Newton TS-41 K is frequently specified as part of broader access and automation solutions. It integrates seamlessly with manual and automated systems, making it a strong choice for projects involving automatic swing doors or specialist door assemblies.
