Compatible with any stove that connects directly to an LP gas cartridge, this foot rest adds stability and safety, especially when you cook on uneven surfaces or with large pots. Simply connect the Primus Foot Rest to the base of the cartridge and you have instant stability. This foot rest weighs less than an ounce and fits not only Primus, but other brands' LP gas cartridges.
