These rubber air cooled, spiral faced backing pads are recommended for use with all ZEC® Semiflex discs.

These pads give maximum support to the disc while the spiral design increases air flow between the ZEC® disc and back up pad.

ZEC® discs run cooler and have an increased life span when used with these air cooled backup pads.

Standard sizes all come with 5/8-11 thread.

Safety and Precautions:

All Semiflex® discs should be used with the proper backing pad. Always wear safety glasses and gloves. Do not exceed maximum operating speed.
