Its adjustable closing and latching speeds, coupled with a robust aluminium build and 500,000 cycle durability, make it a reliable choice where precise, basic door control is required and advanced features like fire rating, back-check, or hold-open are not necessary.
✓ Who Should Buy
- •Building managers and contractors requiring EN 1154 compliant door control for standard interior/exterior doors.
- •Installers seeking a non-handed, surface-mounted closer for wood or metal doors up to 45kg.
- •Facility maintenance teams needing a durable and adjustable closer for moderate traffic areas without fire safety requirements.
✕ Who Should Avoid
- •Applications demanding fire-rated door closer solutions.
- •Installations requiring advanced door control features such as back-check, hold-open, or delayed action.
- •Heavy-duty doors exceeding 45kg or wider than 850mm, which would necessitate a higher EN power size.
Product Overview
The Yale DCR 502 is a highly efficient surface-mounted hydraulic door closer from the DCR Series, specifically designed to provide consistent and controlled closure for standard interior and exterior doors. Utilizing a robust rack & pinion mechanism, this unit delivers smooth operation and precise door management. Constructed from durable aluminium die-cast with a silver finish, it is engineered for longevity and aesthetic integration into diverse architectural environments. The DCR 502 is suitable for wood and metal doors with a maximum weight capacity of 45kg and a width range of 750-850mm, corresponding to an EN Size 2 power output. Its non-handed design simplifies installation, accommodating both left and right-hand opening doors without modification. Key performance features include independently adjustable closing speed and latching speed, allowing installers to fine-tune the door's closing cycle to specific requirements. This model does not include back-check, hold-open, or delayed action functions, nor is it fire-rated. It is certified to EN 1154, ensuring compliance with European standards for controlled door closing devices, and boasts a substantial 500,000 cycle test rating, underscoring its mechanical durability.

Engineering Analysis
The Yale DCR 502 operates on a hydraulic rack & pinion principle, a proven mechanism for controlled door closure. Within the die-cast aluminium body, a precisely machined piston (rack) engages with a gear (pinion) connected to the closer's arm. As the door opens, hydraulic fluid is compressed, storing energy. Upon release, this stored energy forces the fluid back, causing the piston to return and the arm to pull the door shut. The critical aspect of this system is the integration of adjustable hydraulic valves. The DCR 502 features independent valves for controlling the closing speed (from the maximum open angle to approximately 15 degrees from closed) and the latching speed (the final 15 degrees of travel). This allows for precise calibration, ensuring the door closes smoothly without slamming and latches securely into the frame.
Compliance with EN 1154 is a cornerstone of the DCR 502's engineering. This European standard specifies the performance requirements and test methods for controlled door closing devices. For the DCR 502, its EN Size 2 classification indicates its suitability for doors up to 45kg and 850mm width, ensuring optimal closing force for this range. Adherence to EN 1154 signifies the closer has undergone rigorous testing for durability, efficiency, and safety, affirming its mechanical integrity and consistent operational performance. The 500,000 cycle test rating directly correlates with the EN 1154 durability test, validating the closer's long-term reliability under continuous use conditions, a crucial metric for high-traffic applications.
The DCR 502's design explicitly omits back-check, hold-open, and delayed action functionalities. This simplification streamlines its mechanical design, focusing on core adjustable closing and latching speed control. It is important to note that the DCR 502 is not fire-rated. Therefore, its application must be strictly limited to non-fire-door assemblies. The use of aluminium die-cast for the body ensures a balance of strength, corrosion resistance, and a relatively lightweight profile, contributing to its overall durability and ease of installation. The non-handed design minimizes inventory requirements and installation complexity, making it a versatile solution for general-purpose door control where fundamental, reliable operation and EN 1154 compliance are paramount.
