This is an unopened case of 600 count 1-1/4" Utility Snaplock Clips w/ 3/4" Down Leg & Flat Tongue by AMSI Supply for installing standing-seam metal roofing. Each bracket is manufactured of galvanized steel in 24 gauge. The case is left over from a roofing contractor that over-ordered stock. My loss is your gain; if you can utilize them, they are yours for a steal!
