How are V-groove extensions different from flat jamb extensions?
The profile image shows the shaped edge of the V-groove extension. Flat extensions have a flat profile. Compare the edge shape, face width and thickness; the two ranges do not share every size.
Will this V-groove extension fit my existing jamb?
A width alone does not establish a match. Bring an offcut or a clear end-view photograph with measurements so the counter can compare the profiles. The catalogue does not give the individual groove dimensions.
Which V-groove sizes are special order?
Cranco’s April 2026 catalogue marks the 7 1/2 in and 9 1/2 in face widths as special order. Call for the current lead time and ask about availability of the other sizes before planning pickup.
