The magnetic port tray adds a dish right at the entrance of the access ports of the arboreal glass tower enclosures. It facilitates depositing feeder insects right next to the port plugs on the rear wall.
 
It can be used on the bottom and top ports and measure 34x20x9mm.
 
Like the feeding dishes, they allow you to place the food (especially small mealworms) inside the enclosure while preventing the live feeders from touching or burrowing in the substrate (at least it buys you time); they also make it easier for the spider to notice and locate their prey. Each tray comes with magnets pre-attached; and includes the necessary magnets to be attached to the enclosure.
 
Please note the magnets separate the tray from the wall to allow the intricate designs and ventilation of the plastic rear wall to be unaffected. 
 
Please, do not let the magnets snap into place as this could cause the glass to crack; the magnets used are powerful, so it is best to slide them gently into position.
