Clear Acrylic Plastic Cover For One Side of a Metal Screen Lid (lid sold sepearately).
These plastic covers are cut to fit one side of your metal sceen tank lid while the other side is left uncovered to accommodate a heating device such as a hood or clamp lamp. The piece of plexiglass is held in place by a set of movable magnets. Since the magnets are not glued to the cover they can be re positioned to hold the cover partially on the screen lid.
The magnets, when positioned near the edge of the cover, are strong enough to hold the cover in place when the screen lid is opened.
We offer the covers in many sizes for metal screen lids that open left/right and front/back. Use 2 covers to completely cover your screen lid during warmer months.
