Important notesTop plate selection notes:Important application notes: For the Fontaine Top Plate selection guide see page5. Air activated release styles are available on theNo-Slack 6000, 7000, 7000CC series top plates. If any single restriction factor within your applicationis surpassed within a given duty level, the next dutylevel must be selected.Mount selection notes: See page 6 when choosing a Fontaine sliding mount orstationary mount for your top plate and application.– Stationary mount fifth wheels (plate or angle mounts)are an option and ideal for applications where thetrailer kingpin position, kingpin weight, axle loadingand vehicle length are constant or consistent whenloaded. Stationary mount fifth wheels are usuallylighter than sliding mount fifth wheels.– A sliding mount gives the owner more options. Youcan transfer weight between tractor axles, handletrailers with different kingpin settings, and varyvehicle combination lengths. A sliding mount fifthwheel also provides additional maneuverability,accommodates trailers with short landing gearclearance and allows the driver to extend the unitfor maximum comfort when weight allows. If youchoose a sliding mount, Fontaine offers a wideselection of slide lengths in both air activated andmanual release styles. Air release is recommendedfor applications that require frequent adjustment.The flexibility of sliding mount fifth wheels shouldincrease the resale value of your truck. For more information on standard, moderate, heavy andsevere duty, please review the duty class restrictionson page 4. When selecting a fifth wheel, if the application orvehicle usage places the maximum capacity on acertain fifth wheel, then the selection of a fifth wheelwith a higher capacity is advised. For example, a tractorthat is at a maximum vertical load of 50,000 lbs in amoderate duty application should be using a fifth wheelwith a vertical load capacity of 55,000 lbs or greater.This additional capacity should give better service lifeover a longer period of time.Special applications: All logging, mining and oil field applications areconsidered severe duty. Do not select assembliesin the standard, moderate or heavy levels when aspecial application is designated.!!!Minimum static load warning: Minimum static load warning!!! The trailer that isattached to the fifth wheel should impose a consistentvertical load. Repeated negative loading (trying to pullthe fifth wheel off of the brackets with the kingpin) isnot allowed. A minimum static load applied to the fifthwheel through the trailer is 10% of the gross trailerweight. See the load rating for the specific fifth wheelfor maximum vertical load values.Important: Contact your OEM or Fontaine Fifth Wheel for more information on the right fifth wheel for yourapplication. Please refer to the Fontaine Fifth Wheel warranty statement for important warranty information.Selecting assemblies in conflict with this application guide without prior written approval from Fontaineengineering voids all warranties.800-874-97803
