Keep your RV sidewalls clean and streak-free. Camco's clip-on gutter spout extensions attach directly to your rig's existing short gutter spouts in seconds -- no tools, no drilling, no adhesives. Each extension adds 2 inches of reach, throwing rainwater clear of the sidewall so it can't run down and leave those stubborn black streaks behind.
Black streaks on an RV sidewall are almost always caused by dirty water dripping off the roof edge and running straight down the side of the coach. The root of the problem is a factory gutter spout that's too short to throw water clear of the wall. Camco's 42123 extension snaps onto your existing spout and adds 2 full inches of projection -- enough to carry water past the sidewall and let it drop free.
Installation takes about a minute per spout. The extension clips firmly onto the existing short spout; no fasteners, no sealant, and no special tools are involved. The 4-pack covers a typical single slide-out side or handles multiple downspout locations across the roof line.
Snaps directly onto existing short factory gutter spouts. Installs in under a minute with no drills, screws, or adhesives required.
Adds 2 inches of projection beyond the existing spout, directing water clear of the sidewall to reduce staining and black streaks.
Constructed from durable, UV-stabilized nylon plastic that resists sun degradation, warping, and brittleness across seasons of outdoor exposure.
Each package contains 4 extensions -- enough to address multiple spout locations along one side or across the full roof line of most RVs.
The 42123 is designed for RVs that already have short gutter spouts molded or installed along the roof edge. The extension clips over those existing stubs. If your RV has a smooth drip rail with no short spout stubs at all, this clip-on version will not have anything to attach to.
Gutter spout extensions are one of the most cost-effective exterior maintenance upgrades you can make. Black streaks are caused by a combination of roof sealant residue, oxidized roofing material, and airborne dirt that accumulates on the roof and then washes off during rain. Once that water channels off the edge and contacts the sidewall, it drags those contaminants straight down the gel coat or fiberglass paint.
Extending the spout so water drops freely past the sidewall breaks that contact point. Pair the extensions with periodic roof cleaning and a sidewall protectant for best long-term results.
