LN-5 (stainless steel strip) plastic coated waterproof typeFlexible metal wire protection sleeve
LN-5 (NCr) PVC Covered Type

LN-5 (stainless steel strip) plastic coated waterproof flexible metal wire protective sleeve, wrapped with a layer of flexible polyvinyl chloride (PVC) protective layer on the surface of LN-4B metal sleeve using a special method. This product not only has the characteristics of LN-4B, but also has excellent water resistance, corrosion resistance, and chemical resistance. It can be used as various exposed and concealed pre buried and directly buried pipes, and can also replace ground trunking wiring pipes.

LN-5 (Ncr) packet-Prica waterproof plastic casing to protect metal wires, use special methods in
LN-4B metal casing surface, Flexibility is a good coating layer of soft polyvinyl chloride (PVC) protective layer.
Except LN-4B characteristics of the product, there are excellent water resistance, corrosion resistance, che mical resistance ,for all that Dark embedded and buried piping ,wiring can be replaced with ground trough ,etc.
