Aqua One Heater Protector is designed to protect your fish within your aquarium and prevent unforeseen accidents such as falling onto rocks.
Specifications: Suit 25W - 300W (also Fits Thermosafe Heaters)
Aqua One Heater Protectors cannot guarantee that your heater will not break, but they will give your heater a far greater protection than leaving the heater exposed.
The Heater protector is capable of fitting other brands of heaters. The Heater Protector is designed to fit any sized heater up to a maximum diameter of 24mm and length of 350mm. You can shorten the length of the black sleeve by turning the sleeve anti-clockwise from the top one third of the protector.
