America's trend toward larger and brighter signs has prompted Hall Signs, Inc. to develop better brackets to hold those signs. We work with engineers at Purdue University as well as independent labs to develop, test, and monitor our exclusive Hall Signs bracket line. We oversee every step of the bracket manufacturing process to ensure that you are receiving the best bracket products on the market today.
Hall Signs' wide selection of brackets meet every installation need. In our Supr-Lok™ and Ultra Supr-Lok™ lines, choose "F" model numbers for flat street name blades or "X" for extruded street name blades. All brackets using standard SK56 or vandal-resistant PRP38 set screws include a free installation tool.

Hall Signs' Supr-Lok Bracket is the #1 Bracket in America

Our 5 1/2" Supr-Lok™ brackets may be used with U-Channel, Round or Square posts for either flat or extruded signs. A small hole is drilled on each side of the slot and tapped to accept a vandal-resistant PRP38 or standard 5/16" set screw. On the other side of the slot, a 9/16" clearance hole is drilled to allow bolt-through installation. When tightened, the bolt head counter sinks by passing through both the bracket and the sign blank. A special tool is needed to tighten and remove the vandal-resistant bolts. Use the T-100 tool or the free F-100 tool included. IN STOCK FOR FAST DELIVERY! Packaged 50 per box.
