Description: These metal J-hooks are made for wall-mounted display of larger mineral slabs, fossil plates, stone specimens, and other heavy flat display pieces. The hooked shape helps support the lower edge of the specimen while keeping it visible and easy to present on a wall. They are a practical choice for shops, collector rooms, offices, galleries, and home displays where shelf space is limited. Built from metal for strength and stability, these J-hooks are designed to be mounted securely into a wall or backing board. Proper wall anchors or screws should be selected based on the weight of the specimen and the wall type. Ie: with a heavy rock, it is imperative that you hit a stud.
