WHEN ACCOMPLISHING A SCHEDULED SLIDE CHANGE ON THE L1 DOOR, THE REPLACEMENT SLIDE BACK BOARD WAS FOUND TO BE DEFORMED & BULGED IN THE CTR WHICH PREVENTED THE SLIDE FROM BEING MOUNTED PROPERLY TO THE DOOR. THE SLIDE WAS RETURNED TO STOCK AS BAD & WILL BE SENT OUT TO THE VENDOR. ANOTHER SERVICEABLE SLIDE WAS RECEIVED FROM STOCK & INSTALLED ON THE L1 DOOR.
