CABOT~E-A-R~(3) each Eargage~Foam Earplug Sizing Tool
Description: This listing features a lot of (3) each Cabot Eargage Earplug Sizing Devices. E-A-R Aearo Technologies purchased Cabot and now manufactures the Eargage . We acquired these from the U.S. Military and they are NOS (new old stock) in their original packages with Direction Sheets.
From the E-A-R website: "When two-sized foam earplugs are utilized, selection of the proper size product is a concern if optimum protection is to be obtained. As a guide in estimating earcanal sizes, E A R makes available the Eargage tool which consists of plastic spheres of increasing diameter mounted on plastic shafts [approximately 1-mm increments from 7 mm for the extra small (XS) to 11 mm for the extra-large (XL)]. To use the Eargage tool start with a ball that appears to be a close match to the earcanal. Pull the pinna outward and upward while inserting the ball into the canal, with the tab pointing to the back of the ear as shown in Figure 22. The tab of the gauge should not enter the earcanal. It should rest on the flesh directly to the rear of the entrance of the earcanal. If the ball and tab can both slide into the earcanal, try larger sizes; if the ball cannot be inserted far enough, try smaller sizes. The best fitting ball indicates the approximate size of the earcanal. Each ear should be sized individually. When working with two-sized E A R brand foam earplugs, persons with larger earcanals (L and XL) should wear the larger-sized products; those with smaller earcanals (S and XS) should wear the smaller-sized products. Those persons with intermediate sized earcanals (M) can wear either size, whichever works best for them. Final size determination should be made by fitting the actual plugs into the ears. Plugs may be judged to be too small if when removed from the earcanal no sign of deformation can be observed in the product; too large if they create substantial discomfort when properly fitted."
