The weight capacity of a RAM Mount depends on the size of the ball and socket system used. RAM Mount offers three primary sizes: A-size (0.56-inch/14.2mm), B-size (1-inch/25.4mm), and C-size (1.5-inch/38.1mm). A-size mounts can typically support up to 2 pounds, B-size mounts can support up to 5 pounds, and C-size mounts can support up to 10 pounds. However, it's essential to consult the specific product information for accurate weight capacity ratings.
