Robust quality and slightly wider than similar products! Length about 242cm, ie 5cm Sisalscheibe are thus factored, thus results 237cm, which is the exact distance for Steeldart! As Throwline then serves the carpet edge! Only suitable for the protection of laminate flooring since the steel tips but mostly penetrate through the tissue, they should fall down yet again! 100% protection there but nowhere! Strong buy recommendation! PS: The error described by a predecessor with the double-14 has been fixed!
