Feature: Corrosion-proof alloy aluminum or SMC or ABS base and cover. The cover and base feature superior anti-rust performance, suitable for harsh outdoor condition. The cabinet is either pole mounted or wall mounted.IDC and wire wrap modules are available. Suitable for the connection between branch line and the communication line in the city, county and countryside. The type of wall inlaid indoor branch box was suitable for the connection between indoor communication cables and the user lines. (1)Outdoor type：The body of the case is made of aluminum alloy castings, with spray-painted face, elegant and anti-corrosion; the reasonable structure of right-opened case-cover and reversible block leading to better airproof and easy opening or operation. There is pressive button for fixing cable indoor, in order to prevent from dropping of cable lug when forcing; it is better airproof for using rubber sealing loop between the body and the cover; reversible block leading to easy opening or operation; the fixing method as special design can save installation time and to lighten labor intensity of pole in field; add the space of the case properly, that can insure the good sealing of bottom case cover when fully loaded. (2)Indoor type: attractive appearance, borderline smooth, reversible block leading to easy opening or operation.
