Protect the current flowing to your heat mat with this uncoated aluminum mesh screen. Measuring 4 feet long and 11 inches wide, it perfectly fits the 4-foot Agritape Heat Mat, and several screens may be used for the 8-foot and 10-foot mats.
This grounding screen is essential for the safe and effective operation of your heat mat. It needs only one ground connection, and lasts a lifetime. Start seeds, overwinter tropicals, and grow on young plants even in a cold winter room using heat mats with a grounding screen!
