Frequently Asked Questions

What does "cadmium coating" mean? Is it durable?

Cadmium coating is a corrosion-resistant metal coating applied to the metal surface. It offers superior resistance to rust, especially in humid environments. Although its use is restricted in some regions due to environmental regulations, it still provides high performance in existing stock products. Alternative models with zinc or nickel coatings are also available.

Are 5 screws really included with each spring?

Yes. Each door closer spring comes with 5 standard mounting screws. The screws are suitable for wooden/MDF door frames. Different screws may be required for metal frames or special mounting situations; please consult our technical support team.

Which doors is it suitable for?

The Beşel BA650 is designed for standard interior wooden and MDF doors (35–45 mm thick, maximum 30 kg weight). For heavier or wider doors, hydraulic door closers are recommended. Choose based on door weight and usage frequency.

Can the spring force be adjusted?

The BA650 model has a fixed spring force. For adjustable models, please refer to different product codes. The fixed spring is optimized for standard interior doors; performance may vary with extremely light or heavy doors.

Is installation difficult? Are special tools required?

Installation can be done with standard drill, screwdriver, and measuring tools. No special equipment is required. The spring is fixed to the upper corner of the door or the side surface of the frame using screws. Detailed installation instructions and templates are included in the product box.
