Inter Product Gap
The product-specific space that is required to separate adjacent products on a shelf. This accounts for space that holds product dividers. When available, the specified space is added to the left and right of the entire block of a product; half of the quantity goes on either side of the run of that product in the x direction. For example, if there are two facings of product A with inter product gap equal to 1 inch, then horizontally it looks as follows: one-half inch, product A, product A, one-half inch. This applies to pegboards, freezer chests, and shelves. In MSM, this is called finger space beside.
