Dutton-Lainson Tongue Jacks
Dutton-Lainson Tongue Jacks: Engineered for Reliability Since 1886
When it comes to tongue jacks that deliver consistent performance across marine, agricultural, and automotive applications, Dutton-Lainson stands as an industry benchmark. Established in 1886, Dutton-Lainson has built a reputation as a leading manufacturer of quality products for marine, agricultural, industrial, and automotive markets worldwide. This legacy of craftsmanship translates directly into their tongue jack lineup, where over a century of engineering expertise meets modern trailer and boat handling demands.
Specialized Product Lines for Every Application
Dutton-Lainson manufactures marine grade jacks in a variety of weight capacities, height lift travel, jack wheel size and with dual wheels. The brand's tongue jack portfolio spans capacity ratings from 1,000 lbs to 2,000 lbs, ensuring proper support for everything from lightweight utility trailers to heavier boat trailers. Their product range includes sidewind models, swivel mount configurations, and pivoting designs that accommodate different trailer frame geometries and user preferences.
A standout in the Dutton-Lainson catalog is the DLx series, which represents the company's premium jack offering. The DLx marine jack features charcoal gray textured powder coating over zinc plating, dual grease fittings to keep interior parts fully lubricated, a vinyl sleeve on the 1/2" swivel pin for more comfortable swiveling, and a premium cushioned handle grip. These design enhancements address common pain points in trailer handling—corrosion resistance, smooth operation, and user comfort—making the DLx series particularly popular among boat owners who regularly launch in saltwater environments.
Construction Features That Set Them Apart
Dutton-Lainson tongue jacks incorporate several engineering details that distinguish them from generic alternatives. Their heavy duty polypropylene wheels resist flat spots and cold weather cracking, a critical advantage for trailers stored outdoors or in harsh climates. The company offers models with 6-inch and 8-inch wheel diameters, plus dual-wheel configurations that distribute weight more evenly and improve maneuverability on soft ground or boat ramps.
The brand's commitment to durability extends to finish options, with galvanized and zinc-plated surfaces providing corrosion resistance essential for marine applications. Most models feature heavy-gauge steel construction and include all necessary mounting hardware designed to fit trailer frames up to 3" x 5". Travel heights typically range from 10 to 12 inches, offering sufficient clearance adjustment for level loading and secure trailer positioning.
Long-Term Serviceability and Support
One practical advantage of choosing Dutton-Lainson tongue jacks is the availability of replacement parts and repair components. The company maintains an extensive catalog of repair parts specifically for their tongue jack models, including miter gear kits, replacement handles, swivel pins, wheels, and mounting hardware. This commitment to long-term serviceability means these jacks can be maintained and rebuilt rather than replaced entirely, representing better value over the product lifecycle and reducing downtime when components eventually wear.
For operators seeking tongue jacks that balance proven mechanical design with modern corrosion protection and user-focused ergonomics, Dutton-Lainson offers a comprehensive range backed by more than a century of manufacturing expertise in the trailer equipment category.
