Plastic molded units for underground cable protection

Buy offer Details

Dear Sir/Madam,
This is Brian Mclean from UK company based in Shanghai, PRC. WC : brianmcl
Im looking for the following products :
Strong plastic molded chambers which click together to form a protective and separation system for cables to be laid underground. Also needed is the central unit they enter to allow access from above ground.
The chamber is fitted with an alloy frame so a composite ground-level cover can fit on top.
We have images and details on data sheets that will not upload here but will provide on requested.
If we can get these sourced there is a large demand we can order regularly.
We are visting the following provinces shortly so welcome contact from there at the moment : Shandong, Jiangsu, Henan, Anhui.
Thank you.
