RV roof-edge rain gutters, awning rails and J-rails may use small plastic spouts at their ends to direct runoff away from the sidewall. B&B Molders offers several shapes: short, medium, long and flexible long spouts. The rail's width and end profile matter more than the colour alone.

Why the spout shape matters

Short versus long

The short profiles are compact and redirect water beyond the rail's end. The longer profiles project the drip point farther from the RV wall. Choose the shape that matches the original rail termination and the available clearance around awnings, slide-outs and corner trim.

Medium versus 1 1/16-inch rail designs

94170 is intended for the wider 1 3/8-inch gutter rail. The short and long styles listed above fit the 1 1/16-inch rail family. These refer to the compatible gutter-rail profile, not necessarily a measured spout opening.

Left and right identification

The factory catalog identifies separate left and right components. Compare the direction in which water exits your existing spout and the screw-cover or fastening details. Do not assume that a loose part from the opposite roof corner has the same handed shape.

What to measure before choosing

  1. Measure the existing gutter, awning or J-rail profile at the exact end where the spout fits.
  2. Compare the existing spout's short, long or flexible shape and the water-discharge direction.
  3. Check the original mounting arrangement and nearby clearance for an awning or other trim.
  4. Use the appropriate installation and sealing method for the RV's original rail.

Manufacturer profile references

See the B&B Molders illustrated parts catalog (PDF), printed pages 60–61, for the manufacturer's original part-number and component drawings. The PDF may open separately on mobile.

For complete roof-edge rails and molding rather than the end spout, see the RV gutter and roof-edge trim profile guide.
