COMMON QUESTIONS
What to know.
Does a photo tell you the size?
No. Fit comes from measurements you provide. A photo alone cannot establish size or clearance.
Does a size match guarantee a fit?
No. Check depth, backing, condition and any size tolerances in person. The sample below compares width and height only.
