Trim Ring Modification
SHURflo provides 3 different sized trim rings to fit a multitude of RV roof thicknesses.
The three styles and the roof thicknesses for each size are:
Model # Roof Size
21-1316-00 2” to 3-1/2”
21-1316-01 3-1/2” to 5-1/4”
21-1316-02 5-1/4” to 6-1/4”
The trim rings can be cut to adjust height by either measuring the desired height T and
cutting the entire circumference dotted line, or measuring the desired height T, cutting
down at each corner X, scoring the trim ring with a razor blade [dotted lines] and snapping
off the portion to be removed. Snap off plastic by wiggling portion to be removed back and
forth. Be sure to file off any burrs before installing the trim ring. The cuts and scores do
not have to be perfectly straight, because these cuts will be hidden by the fan chassis.
1. Measure T [Roof Thickness]
2. Mark dotted line
3. Cut dotted line; or cut X at 4 corners, score dotted line and snap off.
4. Remove burrs
