Capacity: 1-7 x 10/8 mm or 1-12 x 5/3.5 mm


Duct Branch Closure - Compact



This closure is intended for fast and easy branching of direct buried microduct assemblies for air-blown fiber. The typical application is to branch out 1 to 4 drop ducts to connect single family units from a main duct assembly. The closure is intended for mounting directly into the ground or in manholes, but can also be installed above ground.


Technical Information
Design: Duct branch closure
Type: Underground branching, IP68
Capacity: 1-24 way 5/3.5 mm ducts, up to 8x1-way branch off
