are helpful and easy to understand. If there are any questions, comments, or special considerations, please contact Envirco

It is suggested that the following tools be used to erect this system:
• Laser or Suitable Leveling Instrument
• Phillips head Drive & Cordless Drill
• Circular Saw with Fine Toothed Carbide Tip Blade
• (triple toothed, negative rake, aluminum blade)
• Miter Saw with Fine Toothed Carbide Tip Blade

■ Uncrating, Inspection, and Inventory
The Envirco ceiling system is packaged in the factory in a manner to protect each part during normal shipping and handling. It
is recommended by Envirco that the original packaging remain intact as much as possible until the individual parts are needed.
All extrusion components are packaged in boxes with protective paper between finished 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 confirm that all parts are received
in good condition. Notify Envirco immediately of any discrepancies in quantity.
■ Fasteners Not Provided by Envirco
Envirco does not provide the attachment hardware for the existing structure or framework. All hardware required from the
turnbuckle to the existing support structure is not provided.
■ Special Notes
Due to expansion and contraction properties of aluminum, it is recommended that this system be installed in a temperature
that is as close as possible to that which the finished room will operate. Stock T-bar or wall angle with a length of over 4 feet is
cut with a tolerance of +/-.032”. Stock cross-tees less than 4 feet is cut to +/- .016”. The above stated tolerances are measured
at a material temperature of from 60 to 90 F. All field cuts including perimeter miter cuts are to be performed by the installing
contractor.
