Dormakaba XL-C 1002 Surface-Mounted Hydraulic Door Closer: Precision Control for Commercial Applications

The Dormakaba XL-C 1002 operates on established hydraulic principles, utilizing a contained hydraulic fluid system to regulate door movement. As the door opens, hydraulic fluid is displaced within the closer's mechanism, compressing a spring. Upon release, the spring exerts force, returning the door to its closed position, with the hydraulic fluid providing a controlled resistance. This resistance is precisely managed via two independent, accessible hydraulic valves that permit distinct adjustment of the main closing sweep (from maximum opening to the point of latching) and the final latching phase. This dual-speed control is critical for maintaining security and safety, preventing doors from slamming shut while ensuring positive latch engagement. From a durability standpoint, the choice of steel for the body material ensures high structural integrity, capable of withstanding the operational stresses encountered in high-traffic commercial and industrial environments. The silver finish not only provides a professional aesthetic but also contributes to corrosion resistance. It is imperative to note the specific characteristics provided in the technical specifications: the unit is explicitly designated as `fire_rated: false`. Therefore, its application on fire-rated door assemblies would be non-compliant with building codes requiring such ratings. Furthermore, the data indicates `certifications: N/A` and `standards: N/A`, implying that specific compliance to standards such as EN1154 cannot be asserted from this product information alone. The absence of features like back-check, hold-open function, and delayed action positions the XL-C 1002 as a straightforward, dedicated closing device, focusing solely on the controlled closing and latching phases, without additional door retention or pause capabilities. The 'N/A' for adjustable force range and cycle test rating means that specific performance metrics for these critical parameters are not supplied, requiring users to rely on broader Dormakaba product line reputation for durability if more granular data is unavailable.
