What is the Difference Between the Magna-Track Mounting System and Individual Magnetic Toggle Fasteners seen in the Market?
Individual Toggle Style Fasteners that have an extruded magnet riveted to the bottom of the base of the fastener, adds thickness to the base creating a stand-off which results in there being a gap between the back of the filter screen and the mounting surface – this allows for air and debris overflow which can defeat the filter. Further, the magnetic pull strength of the individual magnetic fasteners is approximately 11 lbs (4.9895 kg) with a lateral / slide strength of only 2.4 lbs (1.1 kg). It should be noted that all magnets no matter their pull strength has substantially weaker lateral / slide strength which allow the magnets to slide easily across the attachment surface hence, when filters are drawn inward under the flow of air, the air pressure transfers the stress to the outer perimeter of the filter resulting in individually attached magnetic fasteners to be pulled toward the intake opening – resulting in the filter losing tension. Note: Once the fasteners have been moved out of position, they tend to cause the filter to gap around the perimeter making them susceptible to removal and loss due to wind.
In contrast, the Magna-Track system uses powerful Rare Earth Neodymium Magnets with a triple nickel / copper / nickel coating that provides a colossal 17 – 18 lbs (7.71 kg – 8.1647 kg) of pull strength per magnet. Because the magnets are inserted into connectors which pull mounting track flush up against the mounting surface, there is NO GAP and NO DEBRIS OVERFLOW. Further, when the quick release twist-lock fasteners are slid into the track they traverse along the track and become self-centering to the grommets on the filter, ensuring a perfect alignment hence filters don’t wrinkle. Additionally, because the track connects together to create a frame, the twist lock fasteners are locked into position and cannot be pulled or slide inward toward the intake opening when the filter transfers the air pressure to the perimeter of the filter – Therefore, the filter screens retain tension and remain firmly affixed to the mounting surface.
