Exodus 27:3-7

Make ash buckets, shovels, basins, meat forks, and firepans, all of bronze. Make a bronze grating for it, and attach four bronze rings at its four corners. Install the grating halfway down the side of the altar, under the ledge. For carrying the altar, make poles from acacia wood, and overlay them with bronze. Insert the poles through the rings on the two sides of the altar.
