The Enduraplas 2800 Gallon Green Horizontal Sump Bottom Leg Tank (SKU THD02800G) is a 2,800-gallon polyethylene horizontal leg tank built for haul service, where the load moves with the trailer instead of sitting in one spot. The green tank measures 145 inches long by 97 inches wide by 75 inches high, giving it a 97.0 x 145.0 inch footprint, and the sump bottom drains the contents toward the outlet so you can empty it cleanly between fills. The number that matters most before you commit: rated to 1.9 specific gravity, it is engineered for up to 44,369 pounds of contents, far beyond a tank built only for plain water.
Will it work for your load
Capacity and weight drive every horizontal leg tank decision. Filled with plain water this tank holds about 23,352 pounds; at its 1.9 specific gravity rating it is engineered for up to 44,369 pounds of contents. Use that 44,369-pound figure when you spec the trailer, axles, and tie-downs, because a dense fertilizer blend or brine will hit your equipment's rating long before the tank looks full. If you are matching tank size to a job, the Tank Sizing Calculator and Tank Sizing Guide help you confirm gallons against the weight your equipment can legally and safely haul. The integral legs and sump bottom are designed to seat the tank on a flat deck and direct flow to the low point for fast, complete draining. This tank's specific outlet and fitting configuration is not in the listed data, so confirm it by phone at 866-418-1777 or against the technical drawing on this page before you build a cradle.
Chemical compatibility
This is a polyethylene tank with a 1.9 specific gravity rating, which is what lets it carry heavy fluids many lighter tanks cannot. Available data points to HDLPE resin, but confirm whether your tank is HDLPE or XLPE by calling 866-418-1777 before any chemical service, since crosslinked and linear polyethylene behave differently with aggressive chemistries. Always match fittings and gaskets to the chemical, not just the tank wall, and watch the metal and CPVC chemistries that trip people up: DEF and Peracetic Acid call for 316SS rather than PVC, Peracetic Acid needs an Aflas gasket, and Sulfuric Acid at 98% requires CPVC. Per OEM chemical-resistance guidance, which is concentration and temperature specific, this tank pairs with examples including: Acetic Acid at 60% (PP/PVC, EPDM), Aluminum Sulfate at 50% (PVC, EPDM), Calcium Chloride at 40% (PVC, EPDM), DEF at 32.5% (316SS, EPDM), Ethylene Glycol at 100% (PVC, EPDM), Ferric Chloride at 50% (PVC, EPDM), Ferric Sulfate at 60% (PVC, EPDM), Ferrous Sulfate at 20% (PVC, EPDM), Hydrochloric Acid at 37% (PVC, Viton), Hydrofluoric Acid at 48% (PP/PVC, Viton), Hydrofluosilicic Acid at 26% (PP/PVC, Viton), Hydrogen Peroxide at 50% (PVC, Viton), Magnesium Chloride at 30% (PVC, EPDM), Peracetic Acid at 30% (316SS, Aflas), Phosphoric Acid at 85% (PVC, Viton), Polyaluminum Chloride (PVC, EPDM), Potassium Carbonate at 50% (PVC, EPDM), saturated Potassium Hydroxide (PVC, EPDM), Propylene Glycol (PP/316SS, EPDM), Sodium Bisulfate (PVC/PP, EPDM), Sodium Bisulfite (PVC/PP, EPDM), Sodium Carbonate at 30% (PVC, EPDM), Sodium Hypochlorite below 16.5% (PVC, Viton), Sodium Thiosulfate at 40% (PVC, EPDM), Sulfuric Acid at 98% (CPVC, Viton), Urea Solution at 50% (PP/PVC, EPDM), Zinc Orthophosphate (PP/316SS, EPDM), and Ozonated Water up to 10 PPM (PVC, EPDM). Match the fitting and gasket material listed for your chemical, and see the full chemical compatibility reference before you commit.
The mistake to avoid
The most common error on a haul tank like this is loading to gallons instead of to weight. Spec your transport to the 44,369-pound rated contents weight, not the 23,352-pound water weight, and confirm fitting and gasket material against the chemical you are actually hauling rather than assuming PVC and EPDM cover it. Review the technical drawing on this page for outlet, sump, and leg geometry before you build the cradle or deck. For background on hauling these tanks, see our guides on applicator and leg tanks for fertilizer, DOT classification for farm fleet use, and fertilizer-blend tank stratification.
