Snyder Industries 125 Gallon Plastic Horizontal Leg Tank

Thirty inches of width is the measurement that decides this one

Measure the space, not the tank. This is the narrow 125, and the whole reason it exists as a separate part number is that some decks are tight across and generous along. A 30 inch width slips into places a wider body will not: down the middle of a bed with the wheel wells still usable either side, along one rail of a utility trailer with room for a pump, a generator or a reel beside it, through a barn doorway and down a walkway to the wall it will live against, onto a narrow flat-deck skid or a rack that has to pass between posts. It buys that by stretching to 49 inches, so it wants length in exchange, and on a short bed that is the wrong trade. The legs are what make either footprint work. They are molded into the underside as flat bearing feet, which means the tank is bolted or strapped down through its own structure rather than cinched over its middle, and the body sits in full contact with whatever it is on. That makes the deck the critical surface: a ribbed bed, a raised toolbox lip, a warped board or a rotted floor turns four bearing feet into two, and the load of 1,042 pounds of water, or up to 1,981 pounds of contents at the rating, finds the high point. Lay plywood or a mat under it on a ribbed bed and let it bear evenly. Then plan for the liquid moving, because a body 49 inches long gives 125 gallons a long run: the surge under braking in a part-full tank is harder than the weight suggests, and it goes into the tie-downs and the deck rather than into the wall. Restrain it fore and aft as well as across. How a leg or applicator tank is classified for road use, and what an agricultural exemption does and does not cover, is set out in the applicator and leg tank classification guide, with the portable utility tank case covered in the loaf-style portable utility tank guide. Check 125 gallons against the real duty in the tank sizing calculator, with the working reserve and the freeboard from the tank sizing guide.

The same 125 gallons in two different footprints

Take this one over the SII-1003600C26 for two reasons and no others. The first is width: this body is 30 inches across where the other is 32, and on a mount where the clearance is measured in inches rather than feet that is the difference between fitting and not. The second is weight on the sheet, because this tank is listed at 46 pounds empty against 55 pounds for the shorter one, which one person notices every time the tank comes off a deck for cleaning. It also carries the larger lid of the two, 10 inches instead of six, which is the real advantage in service rather than in the specification: a 10 inch opening takes a hand, a brush and a light, so this is the 125 to buy for a liquid that leaves residue or for a tank that changes product between seasons. Against that, 49 inches is five inches more length to find on the deck, and on a short bed the wider tank wins. Either way, the sheet publishes both figures and both footprints, and we print what it says. Below the pair, the SII-1031500C26 is the low 65 at 20 inches tall for a mount that has to stay under something. Above them, the SII-1003900C26 is the 225 at 52 by 38 by 42 inches and 85 pounds, and it is the right answer as soon as you find yourself refilling a 125 more than once in a working day.

The outlet is 1.25 inch and the lid is 10 inch, which is the whole difference

• Outlet: a 1.25 inch outlet, as the sheet lists it, at the low end of the body above the legs. Everything downstream is sized by it: it gravity-drains to a hose or a pail, it feeds a transfer or spray pump at a sensible rate, and it is not the port for dumping 125 gallons into a truck in a minute. Level the deck and it drains to the fitting; tilt the deck toward the outlet and the last of it comes out.
• Valve and first joint: a shut-off at the outlet carried on its own support off the deck, and a flexible connector before any hard pipe. A rigid line bolted from the fitting to a pump bracket puts every brake load and every bit of deck flex into the tank fitting, and on a mobile tank that is the failure that actually happens.
• No inlet on this sheet, so none is claimed here: filling is through the lid, with the hose down inside the body rather than splashing across the surface.
• Access: a 10 inch threaded vented lid, the larger of the two lid sizes on the 125 gallon sheets. It is what makes this tank genuinely cleanable, and it is the reason to choose it for a product that settles or dries. Keep it closed in transit and keep the vent clear; a tank that cannot breathe while a pump draws will pull its own wall in, and that happens faster on a narrow body than a wide one.
• Service limit: 120 F / 48 C, with a 3 year warranty as the sheet gives it.

Name the liquid when you order and we will match the outlet fitting, the gasket and the valve material to it against Snyder's current documentation instead of guessing. Two liquid-side cautions are worth putting in writing. If the product is a blended fertilizer solution, the risk in a horizontal body is stratification, because a wide, shallow tank has plenty of surface and very little height to drive mixing, and a blend that has separated will run a spreader off spec before anybody notices; the physics and the field checks that catch it are in the fertilizer blend stratification guide. If the site requires containment, this single-wall tank is not that product, and the Captor double wall containment walkthrough explains what a contained installation has to do to count. Where winter is real, drain the valve, the outlet and the hose and leave the body alone.

Trailer-mounted and bed-mounted transfer on a farm fleet

The narrow 125 earns its place on fleets where every vehicle carries something. A nurse supply riding down the middle of a pickup bed with the wheel wells left free for tools. A spot-sprayer package on a utility vehicle where the pump, the reel and the tank all have to share a narrow deck. Water hauled to stock tanks, a remote pump house or a planting crew. Starter fertilizer or fluid feed carried alongside a planter. Wash-down and dust control water on a construction or utility truck. De-icing brine on a small municipal or contractor rig. A standing gravity supply against a shop wall, where 30 inches of width keeps a walkway open. The pattern is the same every time: the tank is not the interesting part of the system, the deck and the mount are, and the reason this part number exists is to fit a deck the wider 125 does not. Two limits, stated honestly. It is a single-wall tank with no secondary containment, so it is the wrong buy for a liquid your rules say must be contained. And the 120 F / 48 C service limit on this sheet is a number a loaded tank on a dark deck can reach on a summer afternoon, so shade it, fill it cool, or work it down before the heat of the day. Everything else about a long service life is mounting: through the legs, not over the body, with a forward restraint and anchor points you inspect as often as you inspect the tank.

Three plants, one class, and a ship weight of 50 pounds

This tank is molded at Lincoln, Nebraska, Philippi, West Virginia and Merced, California, which means for most of the country there is a short lane to it, and on a light freight item the lane is a bigger number than the class. It moves at class LTL as the sheet lists it, and the sheet gives two weights: 46 pounds empty and 50 pounds to ship. The freight cost estimator prices the lane to your ZIP, and the listed price is before freight. Tell us the delivery address situation at order, because at 49 inches long this is a pallet shipment rather than a parcel and a site with no dock and no forklift is a curbside drop with two people carrying. Look at the legs, the outlet and the lid before the driver leaves. Then mount it and water-test it before the first working load: fill it on the deck it will live on, drive it gently, and check the tie-downs, the legs and the outlet afterwards. Keep the lid gasket clean and keep a spare; on a tank with a 10 inch opening that gets opened often, the gasket is the part that wears out first and the part nobody has on the shelf. Save the pallet; a tank that ever has to move again is easier to move on it.
