This is the Enduraplas internal baffle engineered to drop into the 2800-gallon horizontal Enduraplas tank. It is a component, not a tank: a molded polyethylene wall that spans the inside of the horizontal shell to break up the fore-and-aft slosh of the water column when the tank is towed or run partially full. The baffle carries the tank's internal footprint - Height 20 in, Width 20 in, Length 92 in (a 20.0 x 92.0 in footprint) - so it seats to the shell it was molded for rather than dropping in as a generic panel. That moving liquid mass is the whole reason baffling exists: a fully loaded 2800-gallon horizontal tank holds roughly 23,352 lb of water at 8.34 lb/gal, and an unbaffled column that size shoves hard against the end walls every time the transport slows, corners, or climbs. The baffle chops the span into shorter compartments so the surge stays local instead of loading the ends.
What it does and where it fits
The 23,352 lb figure is the loaded-tank water weight the baffle is there to control, not the weight of the part - the baffle itself is a light molded polyethylene wall. Because it is an internal member, its role is purely mechanical: reduce dynamic load on the tank ends, steady the vehicle or skid it rides on, and cut the fatigue that repeated full-force slosh puts on molded seams. If you are still confirming the tank itself, run the numbers through the Tank Sizing Calculator and the Tank Sizing Guide to lock in that the 2800-gallon horizontal is the footprint you need before you spec the baffle to match it.
The mistake to avoid
Confirm the tank model before you order. This baffle is cut to the 2800-gallon horizontal Enduraplas shell; a baffle sized for a different horizontal tank will not seat correctly, and a horizontal poly tank hauled without matched baffling is the classic way end walls get overworked. Order the baffle by the tank it belongs to, not by capacity alone, and check its 20 x 92 in footprint against the internal geometry on the technical drawing on this page.
This baffle ships LTL by freight, quoted live to your ZIP from the nearest Enduraplas plant - either Converse, TX or Neche, ND. Because it is a large-but-light part at 92 in long, it moves best on the same LTL order as its tank rather than as a standalone shipment: run your ZIP through the Freight Cost Estimator for a live number, or call 866-418-1777 and we will price it against the tank on one order. If your horizontal tank is headed into a fire-water reservoir or rural transport duty, our fire-water reservoir design guide covers how baffled horizontal tanks fit the larger storage stack.
