4 ft drop tarps are the smallest standard side-drop in the flatbed catalog — designed for loads that sit no more than 48 inches above the trailer deck. They are the right call for step-deck trailers, Conestoga systems running over a flatbed, low-profile freight, and any load where a 6 ft or 8 ft drop would just flap in the wind and burn fuel. This sub-category covers every 4 ft drop tarp Truck Trailer Pro stocks, plus the spec sheet you need to decide whether 4 ft is actually the right drop for your trailer and freight mix.
For sizing rules across every drop height (4, 6, 8, 10, 12 ft) and the math behind picking the right one, the full guide is in our Flatbed Tarp Sizes Guide. If you need a different drop height, jump to 6 ft drop, 8 ft drop, 10 ft drop or 12 ft drop — or return to the parent Truck Tarps hub for the full catalog overview.
“Drop” measures how far the tarp hangs over the side of the load — not the load height itself, and not the trailer deck height. A 4 ft drop is the right pick when the cargo sits no taller than 4 ft above your deck. Specific situations where 4 ft drop wins:
| Use Case | Why 4 Ft Drop Fits |
|---|---|
| Step-deck trailers with low loads | Step-deck rear deck sits ~38 inches lower than the front. A 4 ft drop covers the load without dragging on the lower deck or catching air. |
| Conestoga slider conversions | When the Conestoga slider rests over a flatbed deck, 4 ft drop gives end coverage without overlap that the slider cannot accommodate. |
| Palletized freight under 4 ft tall | Standard pallets (40 × 48 in, ~42 in tall stacked) sit right at the 4 ft mark — no oversize tarp needed. |
| Short-stacked lumber bundles | Mill loads under 48 inches tall (small dimensional lumber, finished trim packs) tarp cleanly with 4 ft drop and zero excess. |
| Appliances, white goods, electronics on pallets | Single-pallet appliance loads need rain coverage, not the bulk of a lumber tarp. |
| Aluminum and short coil flatbed work | Light-gauge aluminum sheet bundles and small-diameter coils ride low — 4 ft drop seals the perimeter without slack. |
If your load runs taller than 48 inches above the deck, step up to a 6 ft drop tarp; loads over 6 ft above the deck need 8 ft drop or larger.
| Spec | 4 Ft Drop | 6 Ft Drop | 8 Ft Drop |
|---|---|---|---|
| Max load height above deck | 48 inches | 72 inches | 96 inches |
| Typical weight (per tarp) | 25–35 lbs | 45–60 lbs | 70–90 lbs |
| Solo tarping time (avg) | 15–20 min | 25–35 min | 35–45 min |
| Best trailer fit | Step-deck, Conestoga | Standard flatbed | Standard flatbed |
| Fuel drag | Lowest | Moderate | Higher |
For the deep dive on drop calculation (deck-height vs load-height math, U.S. vs international standards, 2-piece vs 3-piece sets) read the Flatbed Tarp Sizes Guide.
Our 4 ft drop tarps come in two standard cuts plus full custom sizing. Each tarp ships with 3 rows of stainless-steel D-rings, brass grommets at 24-inch spacing, heat-sealed seams and reinforced corner pockets.
Step-deck haulers running daily face two costs most lumber-tarp users do not: (1) the heavier 6 ft / 8 ft tarp drags along the lower step deck, scuffing the bottom edge into early failure, and (2) the extra fabric catches wind across the step transition, costing measurable MPG. A 4 ft drop sized correctly for the load eliminates both problems. On a 100,000-mile-per-year step-deck operation, swapping from 8 ft drop down to 4 ft drop where load profile allows saves roughly 0.05–0.10 MPG — at $4.80 diesel and 6.5 MPG baseline, that is $1,100–$2,200 of annual fuel cost back in the driver’s pocket. The tarp itself also lasts 30–40% longer because it stops dragging the lower deck.
A 4 ft drop tarp is weather protection only — it is not securement. FMCSA cargo securement rules still require independent chains and binders or properly rated straps at the prescribed working load limit. For the full pre-roll process, see the step-by-step tarping guide.
