Sea-Dog Adjustable Pantographic Wiper Arm – Stainless Steel, Black Finish
A heavy-duty adjustable pantographic wiper arm built for demanding marine wiper applications. The Sea-Dog 354-4133221 is formed from 304 stainless steel with a black powder-coat finish, giving it a more substantial construction than the lighter J-hook style arms in the Sea-Dog lineup. The pantographic design delivers a more even wipe pattern than a standard single-pivot arm, maintaining consistent blade pressure across the full sweep 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. Verify your motor shaft diameter and required sweep range before ordering.

Parts Desk Insights
Best suited for applications where a heavier-duty formed stainless arm is preferred over a lighter J-hook style — particularly on larger boats or commercial applications where arm rigidity and durability are priorities. The formed 304 stainless construction makes this a more robust choice than the powder-coated J-hook arms in the Sea-Dog lineup. Confirm your required sweep range and motor shaft diameter before ordering, as the manufacturer does not publish a specific adjustable length range for this model. For a lighter pantographic arm with a specified sweep range, see the Sea-Dog Pantographic Wiper Arm, 13–18 in. – Hook Style or the Sea-Dog Pantographic Wiper Arm, 19–24 in. – Hook Style.
