Are you looking to hang signs from window frames/sills that are not magnetically receptive, such as frames made of finished wood, vinyl or aluminum? If so, we have the solution! This inexpensive, adhesive-backed steel strip attracts magnets and can be used with our line of ladderless magnetic banner hangers. Simply peel and stick to almost any clean, flat surface. Can also be attached to existing magnetic window frame strips for added strength. Use multiple strips to create unlimited lengths. Warning: Do not attach directly to glass, as glass could break during use.

• For use on front face or underside of the top of indoor window frames
• Not recommended for outdoor use
• Black acrylic based adhesive-backed liner
• Custom lengths and colors available
• 0.024" thick white painted steel
