RAM Tab-Lock RPR-381B tablet mount with 3" B size RAM adjustable arm and RAM RPR-271S suction cup base. Mount is in good used condition with signs of use. Mount does have locking mechanism on the base and the adjustable arm however the key is missing and not included in the listing. Again, the key is missing and not included. The base and the arm are unlocked and function properly. Suction base holds firmly on a clean, smooth surface. Base is adjustable and approximate dimensions are 7 3/4" wide and 9 1/2" locked and 10 1/2" unlocked. The height from the base to the top or the mount is 9". The middle port on the mount has had some plastic removed to accommodate a charger and the item has miscellaneous scratches and marks from usage. See photos for details. Thank you
