FAQs
What types of doors is the OUBAO 1035 series suitable for?
The 1035 series is designed for various door types, including wooden and metal doors. It supports doors with a maximum width of 1250mm and a maximum weight of 100kg. Its slim 37mm body thickness allows it to easily fit into standard door profiles without compromising the door’s structural integrity.
Is this door closer suitable for both left and right-hand doors?
Yes, the OUBAO 1035 features a non-handed design. A single unit can be installed on either left-hand or right-hand opening doors, which greatly simplifies installation and inventory management.
Do you provide OEM services for this concealed door closer?
Yes. As a direct source manufacturer, we offer comprehensive OEM and ODM services. Beyond our standard Silver, Bronze, and Gold finishes, we can customize surface treatments, packaging, and specific spring strength configurations to perfectly align with your brand requirements.
How does the self-regulating back-check function work?
The built-in self-regulating back-check creates hydraulic resistance when the door is thrown open forcefully (e.g., by high winds or aggressive use). This prevents the door from slamming into the adjacent wall, protecting the door hardware, frame, and surrounding structures from damage.
Can the closing power be adjusted?
Absolutely. The closing power is fully adjustable by a spring mechanism, covering EN power sizes 3 through 5. This allows installers to fine-tune the tension precisely according to the specific door’s weight and width.
