mandatory shipping KIT - wooden pallet-box (#10M3100) and Pier adapter (#10M3090), both are necessary items when the mount will be shipped by a forwarder. Shipping charges will be calculated individually for each destination and will be billed separately. The Pier adapter #10M3090 will be needed later when mounting the GM 3000 or AZ 3000 onto a dual wall Baader Pier or a customised Pier. This strong plate of solid steel (w. centering flange !) is mandatory not only for securing the mount on the pallet during transport but also later to translate the full loading capacity of the mount into the pillar.
