Any time your coupler may have any metal deterioration, is cracked, bowed, or is unsafe in any way – replace it with an EasyCheck Upper Coupler.
Upper Coupler Types
Upper Couplers (sometimes called the king pin plate, pickup plate, skid plate, upper fifth wheel, or fifth wheel plate) are unique to each type or style of trailer. As a result, there are seemingly an infinite number of upper coupler sizes and designs. EasyCheck’s unique “universal design” strategy solves this problem by simplifying the inventory issue.
EasyCheck Upper Couplers are engineered using our “universal design” strategy. That simply means one EasyCheck Coupler will fit a number of different trailer sizes. For parts and equipment suppliers, our “universal design” feature translates into less inventory needed onsite and more flexibility for installers.
The product code indicates the widths the coupler will fit and the last digit after the dash indicates the bolt spacing on the side rails. For example, product code LGM 353625-3 will fit coupler widths from 35″ to 36 1/4″ (measured from bolt center to bolt center) with a 3 inch spacing between bolts (from bolt center to bolt center) on the side rails. The first two numbers indicate the minimum width of 35″ in this case. The second four numbers indicate the maximum width of 36.25 or 36 1/4 inches. The final number after the dash indicates that the bolts are spaced 3 inches apart on the side rails.
The table below shows sizes available for tank trailer bolt-on style “fixed king pin” type couplers. If the size you are interested in is not shown or you are interested in a “removable king pin” type coupler, we also have those available. Contact us at LGM for more information.
