Bottom view of the enclosure for double-stacked and dual-column 

models, showing panels removed

The single-column model has a 1-5/8 x 13/16-inch strut across the bottom. The 

gland plate beneath the strut can be removed by removing the screws and 

angling the panel to slide it out. The following four views of the single column 

model show the measurements depending on the size of the disconnect and the 

presence or absence of a dead front.
