Cosmetic imperfections
Due to the manufacturing and molding process used for RAM® Mounts components, minor cosmetic imperfections may occasionally appear on certain parts of a product.
The most common area is the aluminium neck directly beneath the rubber ball, where small marks, exposed aluminium or minor coating imperfections can occur as part of the molding and clamping process during production.
These cosmetic variations are considered normal manufacturing characteristics and do not affect the product’s functionality, strength, durability or overall performance.
