Is your cooler missing a foot somehow? Fortunately, replacement feet are available from Bison Coolers and are sold in packs of 2.
These Bison replacement feet are (GEN2) are direct replacements for GEN2 Coolers only. This is the current generation of Bison hard coolers. If the feet on your cooler don't look like these, then you should reference the GEN1 Bison Replacement feet.
