Note : Odd angle elbow flatwise and edgewise elbow sections are available<br />

for angles 95° - 175° in 5° increments.<br />

Flatwise Elbow Sections<br />

Flatwise elbow sections are used for left and right directional<br />

changes when the busway system is mounted in the horizontal plane<br />

(bus bars run parallel to the floor). The joint stack assembly may be<br />

moved to the opposite leg to change the orientation from left to<br />

right/right to left.<br />

Edgewise Elbow Sections<br />

Edgewise elbow sections create up and down directional changes.<br />

The “A”phase bus bar lies on the inside of the bend for edge up<br />

elbows. The “A” phase bus bar lies on the outside of the bend for<br />

edge down elbows. The joint stack assembly on edgewise elbows<br />

can not be moved in order to change orientation from up to<br />

down/down to up. Sentron Busway elbow sections are shipped with<br />

a joint stack assembly on one end for direct connection to the<br />

busway system.<br />
