One side on the back of the main piece came damaged - the damaged side is lifted on the corner and does not allow me to safely and adequately attach the screw. This is extremely disappointing. The box it came in and of itself did not arrive damaged at all, which means the defect came directly from the manufacturer…it seems strange your pieces are not fully screened before packaging. I do not know how to make this work for me unless I try and straighten the piece myself without damaging it fur
