You have a lot of pvc boxes, what is the difference between tuck top boxes and tuck in side boxes?
Basically, tuck top and bottom box and tuck in side box are the same except measured in different way. Tuck top boxes are measured when you put opening lid on upper side and bottom side. Tuck side boxes are measured when you put opening lid on left side and right size. If you turn tuck in side box 90 degree into vertical position, it becomes tuck top and bottom box. 5 (length) X1-7/8 (width) x1-7/8 (height) tuck in side box is exactly the same as 1-7/8 (length) x1-7/8 (width) x5 (depth) tuck top and bottom box. 6 (length) x4 (width) x4 (height) tuck in side box is exactly the same as 4 (length) x4 (width) x 6 (depth) tuck top and bottom box.
