Hello, If like me, you have exactly a sander Bosch "PEX-400AE" and if you receive a plate referenced Bosch "2.609.256.B61.000" it is an original part complies strictly with the rise of plant bearing the inscriptions "PA66GF35". So not a single mounting concern. Tip: put a little good fat in the cup next to the internal mechanism. Two trays purchased, 30% cheaper than at Leroy-Merlin, which also supplies the same reference for this type of sander. When working with this type of electro-portable, the plate must always remain parallel to the piece sanded, because if you exercise outside pressure (it is done more or less ...) you are liable to wear very premature of "Velcro" the sander. Finally, do not hesitate to change the often abrasive disk. Congratulations to AMAZON for the quality of all its services.
