The Hikvision DS-1280ZJ-DM21 (also marketed under the global manufacturer model code CB135) is a heavy-duty junction box engineered from a rugged aluminum alloy material and coated in weather-resistant Hikvision White surface spray. Measuring Ø 137 mm × 42 mm (5.4" × 1.7"), this secure mounting accessory offers a maximum load capacity of 4.5 kg (9.9 lbs) and features interchangeable side and bottom conduit cable entry ports.
