Bushing/Plug for energy boreholes

Bushing for energy borehole, the one in pictures with an outer diameter of 140mm and passthrough for 4pcs 45mm collector hoses.

The bushing is used when backfilling of energy boreholes is required, but you want to limit the depth of backfilling.

The product comes with slots for collector hoses to be easily placed at the intended depth in boreholes.

Other outside diameters, as well as the number and diameter of collector hoses, can be produced on request.

I am interested of this product
