The Brass Door Viewer offered by Beijing Oupuoptic Instrument Co.,Ltd. combines a brass housing with an optical viewing element, allowing users to see who is at a door without touching the handle. The product is available with plastic or glass lenses and comes in diameters of 12, 14, 16, 26 and 28 mm, each finished in a range of surface treatments such as polished brass (PB), chrome plating (CP) and satin chrome (SC). It is packaged in white boxes, colour boxes or blister packs, with optional laser‑etched logos on the cover.
Brass used for the viewer typically follows a Cu/Zn ratio of about 70/30, giving a good balance of strength and corrosion resistance. Standard hardness for this alloy is roughly 150 HB, and the typical tolerance on the outer diameter is ±0.1 mm. The optic lens, when glass, usually meets a visual clarity of 0.8 mm resolution, while plastic lenses meet impact resistance standards for public use. Operating temperature is commonly between -20 °C and 80 °C, suitable for most indoor installations.
Common buyers are security system integrators, property managers and architects specifying door‑viewing solutions for office buildings, residential complexes and public facilities. The supplier lists a lead time of 40 days and provides UL certification for the product, though the exact certificate number is not shown. Shipping can be arranged by sea or air, and the company offers custom packaging and logo imprinting on request; prospective buyers should confirm final trade terms such as Incoterms and payment method directly with the supplier.

Start by confirming the brass alloy composition and the UL certification details with Beijing Oupuoptic Instrument Co.,Ltd. Request a material test report and a copy of the UL certificate to ensure the product meets your target market's safety and quality standards. Verify that the lens material and finish you select are compatible with the intended installation environment.
Discuss the preferred Incoterms; the supplier mentions sea and air freight, so decide whether FOB or CIF aligns with your logistics strategy. The stated lead time of 40 days should be validated for your order volume, and payment terms such as L/C or T/T need to be agreed upon in writing. Ensure that packaging dimensions and weight are confirmed to avoid surprises in freight costing.
Arrange a pre‑shipment inspection by a recognized third‑party agency to check dimensions, finish quality, lens clarity and the presence of the UL certificate. Request a detailed packing list, commercial invoice and certificate of origin to facilitate customs clearance. Maintaining thorough documentation and inspection records will protect your import transaction and help resolve any quality disputes quickly.
