Thorne & Derrick | Distributed from Stocks | UK & Export Sales

Class 4 matting SM570-04 is a high quality fine ribbed rubber insulating matting which is fully certified to meet IEC61111 standards.

The IEC61111 Class 4 matting is fully certified and tested to 50kV with a recommended safety working voltage of 36kV.

Additionally the insulating matting has a fine ribbed, anti-slip surface pattern on one side and a cloth impression finish on the reverse side ensuring safe electrical working conditions for users.

SM570-04 insulating matting is available in cut lengths on request with a thickness of 5mm and widths of 0.91m, 1m and 1.2m.

Class 4 matting in accordance with IEC61111 can also be provided in Grey (SM571-04), Grey/Black (SM572-04) or Orange (SM573-04) each cut to length on request.


Features of Class 4 Matting

Our range of Class 4 insulating matting does not contain any recycled rubber proving the highest levels of compliant electrical safety and protection when working around electrical switchgear, control panels and substations. The electrical matting will safely dissipate current leakage reducing the electrocution shock effect of workers standing on the mat.
