Easy to Understand Summary:
For ANY run of Lundia Shelving, simply add 1 1/4" to the overall width. For example, a 48"wide unit by itself will actually be 49 1/4"wide. 3 sections of 42"wide units will actually be 127 1/4"wide (42" x 3 = 126" + 1 1/4" = 127 1/4")
 
For detailed measuring information, see all our notes and images below....
Very IMPORTANT....these dimensions are generally accurate within an 1/8"...use these dimensions as a guideline. We cannot guarantee absolute critical dimensions:

 

Shelving widths are measured end to end. When placed inside two uprights the overall shelving section dimension will grow by approximately 5/8" on each side inserted into an upright.
Therefore a 36" shelf can end up being 37 1/4"wide including the thickness of two uprights. When sharing uprights to create side by side units, add approximately 1 1/4" to the length to get your overall dimension.

 

Shared Uprights:
How our shared uprights work:

Whenever you have two or more sections side by side you will only need one standard upright between the sections. Our uprights are designed to be shared between shelving sections as noted in the above photos.
