The Enduraplas 250 Gallon Plastic Horizontal Leg Tank (SKU THF00250BK) is a leg-style transport and utility tank built to ride flat on a truck bed, trailer, or skid. The cylinder-on-its-side design with integrated legs keeps the load low and stable, which is why haulers reach for a horizontal leg tank when a vertical tank would sit too tall and top-heavy in transit. At 250 gallons in a 55 x 55 inch footprint and 34 inches tall, it drops into a pickup bed or onto a small trailer without eating your whole deck.
Will it work for your setup
Confirmed dimensions are 55 inches long by 55 inches wide by 34 inches high, with a 55.0 x 55.0 inch base footprint. Plan your mounting frame and tie-downs around those numbers and around the tank's weight when it is full. Water at 250 gallons runs about 2,085 pounds, so the deck, straps, and axle rating under it have to carry roughly a ton of moving liquid plus the tank itself. The legs spread that load across the mounting surface rather than concentrating it, but the frame beneath still needs to be rated for the full figure. One note on the tank wall: the SKU suffix (BK) indicates a black tank, and listed color is not separately confirmed here — with an opaque wall you cannot eyeball the fluid level, so plan on a sight gauge or level fitting if in-service level checks matter to your operation. Match the tank to your job first with the Tank Sizing Calculator and the Tank Sizing Guide before you build the mount.
The mistake to avoid
The most common error with a horizontal leg or applicator tank is treating a water rating as a load rating. This tank's dimensions and full-water weight are verified, but its specific-gravity rating is not listed here — so before you fill it with anything denser than water, confirm the SG rating and resin against the fluid you are moving. The math is unforgiving: the same 250 gallons that weighs 2,085 pounds as water is roughly 2,710 pounds at a specific gravity of 1.3 and about 3,128 pounds at 1.5, and many fertilizer blends fall in that heavier range. If your fluid runs above 1.0, this water-rated haul tank may be under-rated for the load — confirm the SG rating before you buy, and if you need heavier service, ask us about a higher-SG-rated leg tank built for it. For portable and applicator setups, read the DOT rules first: see the 49 CFR 173.5 agricultural-exemption breakdown and the DOT Non-Roadable Trailer scope guide to see where your fleet lands. For fill and blend consistency, the fertilizer-blend stratification guide covers the mixing and field-verification steps that keep a spreader on-spec.
Fittings and drawing
Fitting sizes, port locations, and gasket materials are not published in this listing, so confirm them from the technical drawing on this page or with us before you cut a frame or plumb a fill line — the drawing is the authority for how this specific horizontal transport tank is laid out. One thing worth confirming directly: on any leg or applicator tank moving ag chemicals or fertilizer, the gasket and o-ring elastomer (EPDM vs. Viton) has to match your fluid, since the plumbing seals fail long before the tank wall does. Nail down the fitting and gasket details up front rather than at fill time.
