240 gal stand building

[monocus]

i would double the 2x4-it would also act as a base for your hinges-then again i did not double up or dado my 220 base-i built it like a house-2x4 every 16 inches(except at my doors) Ls in the corners - top frame with 2x4 joists directly above the studs and the bottom framed the same-just use deck screws on an angle to hold everything in place.as soon as you sheet the outside it won't budge
