Heavy-dutycarrying case for the GM 4000 mount. The carrying case and the steel column adapter 16387 must be ordered together with the GM4000 in order to ensure safe delivery by a shipping company and to comply with insurance requirements. Shipping and delivery costs are calculated individually for each destination and will be charged separately. The steel column flange 16387 not only serves as a secure shipping attachment on the pallet, but is also the basis for correct and repeatable mounting of the mount on a Baader levelling flange or a customer's own column. This additional, extremely rigid steel plate (with centring collar!) ensures that the stability of the mount is transferred to the column without any loss.
