For clipping onto a mounting plate, with 2 F+AMMAvA-threaded pins, without mounting screws, equipped with a retaining spring. Now even more durable - the new Dr+AMMAvA-cker rosette with spring retention. This reliably secures the Dr+AMMAvA-cker position even with heavy Dr+AMMAvA-ckers and preserves the optical standard of the object in the long term. Newly designed with optimized, fixed rotating easyfix mounting. The force is thus applied not to the lock, but directly to the T+AMMAvA-bar.
