This is the break-through in hea ting that we have all been waiting for at a very reasonable price. These heating cords are ideal for use in your incubators; no more changing blown globes all the time! They are also a great heat source for your reptile enclosures; you can place them behind a false wall or under a false floor. The list of uses for this heating cord is endless. We have even sold it to a large boarding kennel to keep the woofers warm. Fauna rescue groups also love these heating cords as it helps keep a larger percentage of there rescued animals alive and we think thats great! Available in four sizes and wattages. Wired to Australian Standards. Should be used in conjunction with a thermostat like any other heat source.
