The PPKP-M8 and PPKP-M10 high nuts are designed for mounting PPKP-M8 or PPKP-M10 threaded rods to the PPKP-M8x60 or PPKP-M10x70 anchor bolts in the case of a hanging installation of the cable trays. They can also be used to extend threaded rods. The appropriate fasteners depend on the base and load of cable trays and cable ladders.
