Today, Dutton-Lainson Company is one of the country's leading manufacturers of quality products for marine, agricultural, industrial, and automotive markets throughout the world.</p><h3>Heritage of Innovation and Quality</h3><p>In the 1940s, the company retooled to meet the needs of a world at war, and during this time received three Army-Navy E pennants, an award signifying the highest level of quality and service given to only 5% of the country's manufacturers at that time. This legacy of precision manufacturing and reliability continues today in every product that bears the Dutton-Lainson name. For well over a century, Dutton-Lainson Company has been respected for its innovative spirit and highest standard of integrity, meeting the needs of its customers by finding new ways to diversify and enhance its product lines and service.</p><h3>Essential Equipment for Work and Recreation</h3><p>Dutton-Lainson's product lineup focuses on the critical equipment needed for hauling, lifting, and securing loads across multiple industries.

Product Details

The Dutton-Lainson 21754 is a 4-foot roller bunk kit designed for boat trailer applications. This kit provides smooth loading and unloading support for your watercraft, protecting both the boat hull and trailer frame during transport.

Key Features:

  • 48-inch length provides extended support for boat hulls
  • Durable roller design reduces friction during loading and launching
  • Sold as a matched pair for balanced trailer setup
  • Heavy-duty construction for marine environments
  • Easy installation on standard boat trailer frames

Roller bunks are essential components for boat trailers, offering superior hull protection compared to traditional carpeted bunks while making it easier to load and unload your boat at the ramp. The roller design allows your boat to glide smoothly onto the trailer with minimal effort.

So far so good

order went smoothly

Very simple. Would use again.

autoplicity from now on will be my first call. everything was just what they said. and delivery was the best time ever. placed order sunday night had part wed. morning. WOW thankz

I got the part I ordered and will be having someone install it soon looks just fine and I love the chat feature as well.. thinking about buying brake shoes now.. a lot of savings

The prices were so much better with Autoplicity I couldn't believe it was the same item. E-mail response came within an hours. Will buy from again.<br><br>Ok, the verdict's still out on this one. Autoplicity said my item was shipped two days ago (two days after ordered), but FEDEX indicates they've only received "shipment information", after four days. I'll follow up when I actually see the order.

Best prices, fast shipping, and product as described. I would definitely recommend Autoplicity.

You have what I need.

Good prices and availability of parts. I will definitely be ordering more parts from here in the future. My order shipped very quickly and I was impressed by the quality of the part when it arrived.

GOOD
