Here are my calculations please correct me : Top to bottom: 6x4"+4" = 28" Back to front: 6x4" + 4" = 28" Entry to exit point distance: 6x4" = 24" So I need a 28" high 28" deep box. Width doesn't matter. Am I correct? ptonsparky Senior Member LocationJan 15, 2019 · Right Side Z Value- We still have our base size from our previous calculation, which is X=24" x Y=17" but now we have to add the "Z" dimension. Moving to the Right Side of the pull box, using 314.28 (A) (2), 6 x 2.5" = 15". While there are two routes out of the right side, one path from a 2.5"to a 2" and another path from a 2.5" to a 1.5" raceway. Considering an angle pull, if the enter and exit walls contain raceways of 3, 2 and 1 in. respectively, multiply 3 inches by 6, and add 2 inches and 1 inch. That equals 21 inches. Therefore, the size box for an angle pull is 21 inches by 21 inches. As another rule of thumb to size a box for an angle pull, multiply the largest of the raceways by 10.
