Exodus 36:20-34

Then they made upright frames of acacia wood for the Holy Tent. Each frame was fifteen feet tall and twenty-seven inches wide, and there were two pegs side by side on each one. Every frame of the Holy Tent was made this same way. They made twenty frames for the south side of the Tent, and they made forty silver bases that went under the twenty frames. There were two bases for every frame—one for each peg of each frame. They also made twenty frames for the north side of the Holy Tent and forty silver bases—two to go under each frame. They made six frames for the rear or west end of the Holy Tent and two frames for the corners at the rear of the Holy Tent. These two frames were doubled at the bottom and joined at the top with a metal ring. They did this for each of these corners. So there were eight frames and sixteen silver bases—two bases under each frame. Then they made crossbars of acacia wood to connect the upright frames of the Holy Tent. Five crossbars held the frames together on one side of the Tent, and five held the frames together on the other side. Also, five crossbars held the frames together on the west end, at the rear of the Tent. They made the middle crossbar run along the entire length of each side and rear of the Tent. It was set halfway up the frames. They made gold rings on the sides of the frames to hold the crossbars, and they covered the frames and the crossbars with gold.
