Sea-Dog Adjustable Pantographic Wiper Arm, 19–24 in. – Hook Style, Black
A heavy-duty pantographic wiper arm built for larger boat windshields that need wide, even sweep coverage. The Sea-Dog 354-413374B1 is constructed from powder-coated 304 stainless steel and adjusts from 19 to 24 inches, giving you the flexibility to dial in the right sweep length for your windshield without swapping arms. The J-hook (automotive-style) blade attachment makes blade replacement quick and straightforward — no special tools, no proprietary clips.
The pantographic design delivers a more even wipe pattern than a standard single-pivot arm, maintaining consistent blade pressure across the full arc. Compatible with most standard MRV and heavy-duty waterproof wiper motors with a 5/8 in. shaft diameter, as well as 1.5 in. and 2.5 in. shaft motors.

Parts Desk Insights
Best suited for larger boat windshields where a 19–24 in. sweep range is needed and a pantographic arm is preferred over a single-pivot style. The J-hook attachment is a practical advantage — it accepts the same blade style used on most automotive and marine blades, making replacement easy anywhere. The pantographic design is particularly effective on wide windshields where a single-pivot arm would lose contact pressure at the outer edges of the sweep. For a stainless (non-black) pantographic arm option, see the Marinco 33090 Premier Stainless Steel Pantographic Wiper Arm, 12–17 in. For a shorter adjustable arm, see the Marinco 69-33032A Deluxe Adjustable Pantographic Wiper Arm.
