Magnetic vent cover

A vent cover for covering a terminal end of air duct work, the vent cover comprising:

• (a) a top surface comprising at least one aperture therethrough, opposed lateral walls extending outwardly from the top surface to define an interior cavity adjacent the top surface, and movable opposed end walls extending between the opposed lateral walls,
• wherein the opposed end walls are slidably engaged with the opposed lateral walls for lateral movement therealong, and
• the opposed lateral walls and the opposed end walls are capable of being sized to fit within the terminal end of the air duct work;
• (b) at least one actuating member disposed within the at least one aperture and operably connected to a magnet, the magnet selectively positionable against the air duct work;
• and
• (c) a bias means for biasing the at least one actuating member into a securing position wherein the magnet is adjacent the air duct work to secure the top surface against the terminal end of the air duct work;
• the at least one actuating member movable between the securing position and a releasing position, wherein in the releasing position the at least one actuating member opposes the bias means to space the magnet from the air duct work to allow the top surface to be moved away from the air duct work.
