SJ-D-S  Waterproof  Dome Fiber Optical Splice Closure, Joint Box, Fiber Dome Closure, Fiber Dome Splice Closure 


Fibre optic dome splice closures from Sijee  allows 2 cables in and 2 cables out. It accommodates the splicing and branching of the cable which is used in aerial-hanger, wall-mounting or direct buried. The Closure is an openable box which is made from high-quality PC. The closure and the foundation plate are sealed with Silicon Gum Material which fixes tightly by hoop. And the sealing of cables also uses Silicon Gum Material. 
The Closure can be opened and used again, no need to change the sealing materials after it be sealed.
