1. Stainless Steel or galvanized hanging brackets. Available for flush mount on wall, or 1/2" - 5-1/2" railing. Recommend approx. one bracket per foot of Coronado Box (i.e., a 48"L box would require 4 brackets).
   
2. Changeable parts: Stopper, inlet discs, retainer rings, one-sided grommet, sensor tube, soil separator fabric and root confuser discs. All parts shall be included with Coronado Boxes at installation and shall be removable and replaceable.
   
3. Bioguard Root Control Fabric: To prevent plant roots clogging the inlet holes, leading to premature failure of system. Bioguard is EPA-registered root control fabric coated with Trifluralin, a herbicide that prevents root cell division. Biobarrier cut into 3" squares by Planter Technology, Inc.
   

1. Prior to Coronado Box fabrication, the contractor shall verify as-built dimensions of planter areas to ensure proper size, fit and quantity required. 2
   

1. Space brackets evenly along length of unit. Firmly screw bracket into wall, or into railing (if applicable)
   
2. Install liners level to permit adequate drainage and irrigation.
   
3. Do not trim or modify the Coronado Box in any way without first consulting with and receiving approval from the manufacturer.

1. Excess rainwater buildup can lead to "root rot" and less healthy plants. On-site drain installation by contractor may compromise integrity of vacuum reservoir and is not recommended. Exterior drains are supplied by manufacturer with removable stopper to control drainage.
2. Field verification of actual planter receptacle size is frequently overlooked by the contractor, and can lead to delays and additional cost if neglected.
