Protection grills affixed to Cata-Dyne™ heaters are installed to protect personnel and objects from coming into direct contact with the face of the heater. They are available in two styles: Strap-On and Snap-On. Strap-On grills are bolted to the heater box with straps, whereas Snap-On grills snap on to the bezel of the heater for quick and easy installation without the need for tools or hardware.
