One of the primary advantages of butt hinges is their ability to accommodate heavier loads over other hinges. This is due to their bigger knuckle, which provides more support for the leafs. In addition the hinges on butts are more able to handle expansion and contraction, which makes them more able to withstand extreme temperatures.
