This damage usually involves the frictional forces encountered with dealing with rough edges or unusually sharp corners. Yet, one may still be confused as per the exact size specifications of the rubber grommet they are looking for on rubber grommet hole size chart. The most straightforward method to determine size is of course involves measuring the width and other dimensional aspects of the panel. This means inculcating the size of the hole in which the grommet will be stashed and the characteristic of the object that will be put through it. 

Rubber Grommets are designed to be tear-proof and have been known to possess an inherently strong resistance to temperature. This phenomenon of course helps ensure a small cushion around minute openings. This is where the grommet hole size chart comes into play as it consists of three sizes that display the internal, external and depth measures of a grommet in mm.

The internal depth can vary between 4-50mm. Industrial machinery is usually best served with a rubber grommet, and these grommets can go a long way in keeping stray fluids & debris out of essential machinery, and their internal components. However, if grommets are to work effectively they must be placed and sized accordingly. A grommet hole size chart will help you determine your exact needs, as it can establish the size required for a specific piece of machinery.
