¡ÝThe EPLAP joint closures are most advanced heat-shrinkable closures for protection of
cable joints in the telephone network.
¡ÝThe EPLAP closures have an excellent split resistance during application and very
¡ÝThe glass composite structure of closure offers superior resistance to mecanical abuse
during and after the installation
¡ÝAn integral metal layer which shrinks with the sleeve protects the joint from moisture
The EPLAP joint closure are avaliable in an extended size range having a joint capacity
up to 800 pairs
The kit comes complete with a variable liner,which insulates shapes and dompacts the
joint bundle and the unique three finger clip with hot melt adhesive.
The kit is suitable for non-pressurized,buried or ducted,non-filled or jelly filled,with lead
or polrenthlene sheaths.
