Elbow assembly for use with divided raceway having T-shaped base
A divided raceway has runs that must traverse a corner in a wall structure. A raceway elbow assembly has an L-shaped base with mutually perpendicular leg portions adapted to abut the wall at that corner. Divider walls are carried by these flat leg portions, but allow flexing of the elbow leg portions as a result of a V-shaped gap between the divider walls at the vertex of the L-shaped elbow, or as a result of the divider wall overlapping one another in this region.
