The adhesive backing used on our nylon cable tie bases has been tested in the most varied conditions and extreme temperatures. We can therefore confidently recommend their use on most smooth, dry, clean and grease free surfaces. Recommended temperature -20°C to +60°C, but it is advised that the bases should not be applied when temperatures are very low. To ensure complete security where excessive stress or vibration is likely to occur, a screw mounting hole is provided on the HFC 2/4.
