50m 100mm yellow perforated ducting coil for gas applications.

This ducting is a single wall perforated corrugated duct manufactured in yellow as specified by Transco. Drawcord supplied separately.

Although utility networks prefer to lay gas pipe in an open trench, some allow ducting like this to be pre-laid for gas pipe to be installed at a later date. Ducting is perforated to enable detection of leaks. 

Manufactured to BS 4962 (Kitemarked).
