Stop streaking through rain on the highway. The AP Products 018-546 is a full 35-inch clip-on replacement wiper blade designed specifically for the oversized windshields on Class A and Class C motorhomes. With a 7/16" x 3" wiper element and a clip-on attachment style, it drops right onto standard RV wiper arms without adapters or tools.
Passenger-car wiper blades simply are not long enough to clear the tall, wide windshields on Class A diesel pushers, gas motorhomes, and larger Class C coaches. AP Products' 018-546 is sized at a full 35 inches to give broad windshield coverage where it counts -- at highway speed in heavy rain.
The clip-on mount is the most common attachment style found on OEM RV wiper arms. If your current blade uses a simple metal saddle clip that snaps over a pin on the arm, this blade is the correct style. No adapter kit is needed for standard clip-on arms.
Full 35-inch swept length provides wide windshield coverage sized for large motorhome glass -- far longer than passenger car blades.
Standard saddle-clip mount snaps directly onto pin-style OEM wiper arms common on Class A and Class C motorhomes. No adapters required.
The included 2-inch wiper element matches the 7/16" x 3" refill profile, giving a firm wipe contact across the full blade length.
Engineered as a drop-in replacement for worn or streaking OEM-style wiper blades on AP Products-equipped and aftermarket RV wiper systems.
Clip-on (also called pin-type or saddle-type) wiper arm attachment is the standard fitment on the majority of Class A motorhome wiper systems. The wiper arm has a small raised pin or post; the blade's metal yoke snaps over it with a retaining tab. This is different from the hook-style or bayonet-style arms found on some passenger vehicles and certain European-designed chassis.
Before ordering, check your current wiper arm: if the blade removal involves pressing a tab at the center pivot and lifting straight up off a pin, this is the correct style. If your arm ends in a curved hook, you will need a hook-style blade instead.
The designation 7/16" x 3" refers to the cross-section of the rubber wiper refill element that rides against your windshield glass. The 7/16" dimension is the element width (top-to-bottom profile) and 3" is the bridge or backing width -- the measurement your blade yoke clamps around. This is a widely used refill size in the RV and commercial vehicle wiper market, which means replacement refill elements are easy to source when the rubber wears out and you do not need to replace the entire blade assembly.
