48" span of 12 gauge HS-Style unistrut will require 3 anchors per section
Each anchor must hold 870# / 3 = 290# in shear

Use a 48” to 60” length of 12 gauge HS-Style unistrut using 3 anchors per section with a maximum spacing of 10 ft between unistrut supports.  Imbed ½” threaded rod 4” deep into the brick mortar and anchor the threaded rod using an epoxy system equivalent to Hilti HY-20 Hybrid Anchoring System.  

Use a 48” to 60” length of 12 gauge HS-Style unistrut using 3 anchors per section with a maximum spacing of 10 ft between unistrut supports.  Imbed 7/16” threaded rod 4” deep into the brick mortar and anchor the threaded rod using an epoxy system equivalent to Hilti HY-20 Hybrid Anchoring System.
