All extrusion components are packaged in boxes with protective paper between nished surfaces.
As the skids are received at the job-site, they should be placed in a location near the installation area, where they will not
become an obstacle, or require to be moved at a later time. The skids should then be opened, however leaving the internal
packaging unchanged. Pieces should be removed on an as needed basis and the packaging discarded. At this time, however,
the components should be visually inspected for obvious damage and an inventory taken to conrm that all parts are received
in good condition. Notify Envirco immediately of any discrepancies in quantity.
■ Fasteners Not Provided by Envirco
