The Takahashi TKA37421 plate provides offset for mounting the FSQ-85EDX collar. It is designed to shift the assembly’s position relative to the mount and make it easier to balance when the short tube’s weight distribution makes direct mounting less suitable.
The manufacturer lists the TKA21420 one-piece clamp and the TKA21420G symmetrical clamp. This mounting plate is not a replacement clamp; it serves as a mounting interface for these part numbers. It is therefore important to verify the part number of the clamp already in use, rather than relying solely on the name of the bezel.
The plate has two M8 threaded holes, three 1/4-inch-20 threaded holes, and five 9-mm-diameter holes. These mounting points are shown on the official top and bottom views. Check their layout for your installation; no additional center-to-center distances or specified offsets can be inferred from the photograph.
The French Takahashi product sheet indicates compatibility with the EM-11 and EM-200 mounts. Balance must be checked with the optical train actually installed. The clamps, tube, and mount mentioned are provided to specify the intended use of the plate; they are not listed as included. The weight is not listed in the table on this French product sheet.

Takahashi TKA37421 offset plate for the TKA21420 95S collar on the FSQ-85EDX; it helps balance the tube. The TKA21420S set and the FSQ-85EDX package with accessories already include both parts. Check the mount, mounting, and balance.
FSQ-85EDX tube only; the mounting clamp and its offset plate must be purchased separately. The accessory pack already includes the 95S set with the plate.
FSQ-80FC sold separately. When used with the separate 95S clamp, this Takahashi KB-S plate allows the tube to be moved forward to facilitate balancing; check the setup and load on a Takahashi EM-11 or EM-200 mount. The 95S prevents the dew shield from retracting completely.
