A. Compatibility models: It is suitable for random orbit models like DWE6423/6423K, DWE6421/6421K, DWE6421-, DWE6421 - B3, DWE6421 - BR, and DCW210B. It can directly replace shim part numbers DWE64233 and N329079. B. Metal backplate: The metal backplate differs from the original plastic backplate. It is harder and less likely to be damaged. C. Soft rubber pad: The soft rubber can reduce the vibration generated by the orbit, making the work smoother. The 8 - hole design helps with effective dust collection. D. High density: It has high density, uniform and strong adhesion, and a relatively long service life. E. Easy to install: It uses a simple screw - mounting method. The installation is relatively easy. (Note: Screws are not included. You can use the existing screws on the device.) F. Colors: Black and silver G. Material: Metal H. Dimensions: 125 mm I. Package contents: 3 shims J. Only the above package contents are included, and other items are not included. K. Note: Light and different displays may cause the color of the item in the picture to be slightly different from the actual object. A measurement error of ±1 - 3 cm is allowed.
