Square brackets are available with varying slot widths for flat or extruded sign blades. Larger signs and the newest sheeting types from 3M™ are thicker, so we recommend you consider ordering extruded bracket models for .125 or thicker blades, or check with a TAPCO representative if you have questions. All brackets include plated steel set screws unless specified otherwise. Vandal-resistant and stainless steel screws may be ordered separately. Our brackets are available unpainted (raw) or painted 60% gloss vulcan black. Other custom colors available: minimum quantities may apply.
