Construction
- Chamber cover finial elements made from polymer are suitable for:
- RadBox cable connection chambers;
- Any other appropriate chambers.
When assembling polymer chamber cover elements, one above the other, use silicone mastic, Ø 3-5 mm in two strips, on the surface of the polymer element!
During the assembly process the following remarks must be taken into account:
- Do not assemble the polymer surface finial elements on an unprepared ground, uneven, unlevelled, and unrepaired surface supporting the adjustment elements and in case of relief elements - on an uncompacted ground or substructure;
- Do not use cement-based mortar between polymer elements in the finial structure and between polymer and cast-iron elements of chamber finial;
- Do not make high adjustment based only on compensation rings with small dimensions (e.g. 21 cm adjustment made using 10 pcs of 15 mm rings and 2 pcs of 3 cm rings), as the possibility of height problem occurring during the operation increases the finial costs without any justification;
- Make sure that that frame of chamber cover is perfectly placed on the polymer elements.
- Chamber cover finial elements made from polymer are suitable for:
