Applications and feature:
l STB is a high reliability connection module, designed to withstand all exsiting climates.
l Watertight by design, it provide the best service for the following applications:
Interface boxes UG/Aerial Networks
Distribution points
Customer termination devinces.
l Fits on DIN 35 rails
l Very compact, overall dimensions allow to replace exsiting won protected solution by a high reliability solution
l No special tool required, only by standard screw driver.
