1. Compatibility models: Suitable for random orbit models such as DWE6423/6423K, DWE6421/6421K, DWE6421-, DWE6421 - B3, DWE6421 - BR, and DCW210B. It can be a direct replacement for shim part numbers DWE64233 and N329079. 2. Metal backplate: The metal backplate differs from the original plastic backplate. It is harder and less likely to be damaged. 3. Soft rubber pad: A soft rubber pad can reduce the vibration generated by the orbit, making the work smoother. The 8 - hole design is beneficial for effective dust collection. 4. High density: It has relatively high density, uniform and strong adhesion, and a relatively long service life. 5. 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.) 6. Colors: Black and silver 7. Material: Metal 8. Dimensions: 125 mm 9. Package contents: 3 shims 10. Only the above package contents are included, and other items are not included. 11.
