Hang-It Display Systems single-arm steel wall display brackets are made from a 16 gauge mild steel with powder coating colors. The flat black color complements Riker boxes and darker fossils. The cream color matches lighter fossil plates. All brackets have a 1 inch ledge and come with wood or drywall screws for mounting. Product Information: Hang-It Display Systems single-arm specialty display brackets are more flexible in their uses than the traditional double-arm brackets. They can be used in conjunction with a double-arm bracket or on their own. Single-arm brackets work especially well with irregularly shaped fossils. If the bracket can be attached to a wall that is wooden or has studs, the included wood screws can be used. If the bracket needs to be attached to drywall with no stud behind it, use a plastic drywall anchor. Attach the bottom bracket to the wall first, using a bubble level to make sure the bracket is level. Place the display item on the bracket and mark the top with a pencil on the wall. Remove the display and then use the pencil mark to secure the top bracket in position. The single-arm bracket has an adjustable ledge with a tension screw. Sold individually and as a set of 2, 3, or 4. Please contact us for volume discounts and wholesale prices. Made in the USA.
