Extrusion Clip Mounts use Custom Nuts inserted into extrusion slots for attaching StandOff, EZ-Rod & Wire and Wire Suspension components to our StructureLite proprietary extrusions. They use our typical 5/16-18 thread for fastening. These assemblies use Shelf Clips and Barrels for perpendicular mountings. The addition of Pulley Hinges makes attachment angles variable up to 90 degrees.
