We can also manufacture other sizes, such as 4"x5", Square Corrugated and Smooth elbows are 2"x3" and 3"x4". This causes an elbow to not last as long.Ĭustom degrees are available for square smooth and plain smooth elbows, where they would be 2 solid pieces put together rather than one piece with incremental bends. Seamless elbows are offered in 40°, 72° and 85°.Īlthough normally referred to as 45s or 90s, the standard elbow angle is actually 75°.Įlbows with harsh angles, such as 90° elbows are usually not recommended, although needed in some situations, these elbows allow for water to directly hit their bottom side without being carried at an easier angle like a 75° for example. In a standard gutter installation, if you are facing the gutter for example,Īn A Elbow is the elbow that will come out off the wall or gutter straight to you.ī elbows would be the ones that would fit the downspout and carry the water either to the left or the right, instead of out (forward) or in (backward).Įlbows normally come in #0 (30°), #1 (45°), #2 (60°), #3 (75°) and #4 (90°). The difference is the directrion the elbow faces. What is the difference between A Elbows and B Elbows?
