Our frames are made of aluminum and manufactured with snap frames to allow for easy unloading and loading of your signs. Simply lift the edges up, load your insert, and snap the edges back down for a tight hold. The great thing about our directory sign frame is that it is front loading, which means that you won't need to remove the sign from the wall to change your graphics once it is mounted. The snap frames are located on the front of the sign for maximum loading efficiency. We carry various sizes of directory sign frames ranging from 11" x 17", all the way up to 36" x 48" so you can choose which size works best for you!
