Import Door Closer — Buy in Bulk from Supplier in China

The Door Closer offered by Hebei Zender Chemicals Co.,Ltd. is a hydraulic or pneumatic device that controls the closing action of interior and exterior doors. It features an adjustable closing speed and latch action, allowing the installer to fine‑tune the device for doors of varying weight and usage frequency. Constructed from forged steel with a zinc‑plated finish, the unit is compact enough to be mounted on a surface without obstructing the door leaf. The product description highlights its role in preventing door slamming and extending frame life.

Typical closing force ranges from 5 N to 15 N, with arm lengths around 100 mm, providing sufficient torque for doors up to 80 kg. The body dimensions are generally 150 mm × 120 mm × 65 mm (typical) and the unit operates reliably between - 20 °C and 80 °C, matching standard environmental specifications for commercial hardware. Compliance with ISO and CE standards is common for such devices, although the supplier does not list specific certification numbers.

Potential buyers include hotel chains, retail outlets, office buildings and residential developers seeking to meet safety regulations. As the supplier does not publish MOQ or lead‑time, importers should request those details directly, together with packaging specifications such as cardboard boxes with protective padding. Trade terms are usually negotiated as FOB or CIF, with payment by L/C or T/T after the commercial invoice is issued.
