9' X 18' F/S 18 oz. Black Vinyl Dump Truck Tarp, with side flaps and shock cord

The 9' x 18' F/S 18 oz. Black Vinyl Dump Truck Tarp with Side Flaps and Shock Cord from DeBrovys is a premium, 100% waterproof replacement tarp engineered specifically for front-to-rear (F/S) electric and manual tarp systems on dump trucks. Unlike standard flat tarps, this model features integrated side flaps with shock cord that hang over the sides of the dump body, creating a complete seal that prevents loose material and water from escaping at the edges. Manufactured by DeBrovys, this tarp is built for heavy-duty applications where keeping the load completely contained and dry is essential — such as hauling asphalt, hot mix, topsoil, grain, or environmentally sensitive materials.

Constructed from industrial-grade 18-ounce vinyl-coated polyester, this tarp delivers unmatched weather protection and tear resistance. The 6" rear pocket slides directly onto your tarp spool, the spline locks securely into the front edge of your tarp bar, and the full-length #6000 2" automotive-grade seatbelt webbing keeps the sides taut and secure at highway speeds. The shock cord sewn into the bottom edge of each side flap holds the flaps firmly against the truck body, eliminating wind whip and preventing side spillage.

Why Side Flaps with Shock Cord Make the Difference

Standard dump truck tarps cover only the top of the load, leaving the upper sides of the dump body exposed. When hauling fine materials like sand, topsoil, or grain, material can still escape over the side rails — especially at highway speeds. The side flaps with shock cord on this tarp solve that problem entirely. Each flap is a wide panel of 18 oz. black vinyl that extends downward from the long side hems, draping over the top edge of the dump body walls. The heavy-duty shock cord sewn into the bottom hem of each flap stretches and hooks to the truck body, holding the flaps snug against the sides through every bump and turn.

This design is particularly valuable for operators hauling fine aggregate, topsoil, or grain where even small gaps at the top of the side walls can result in spillage, fines violations, and road hazards. The side flap and shock cord system provides the complete containment that a flat tarp simply cannot achieve.

Technical Specifications

Who Uses This Side Flap Vinyl Tarp?

This 9' x 18' black vinyl dump truck tarp with side flaps and shock cord is the preferred choice for owner-operators and fleet managers who need complete load containment — not just top coverage. It serves the following industries:

• Asphalt & Paving: Retaining heat for hot mix asphalt during transport while sealing side gaps
• Agriculture & Farming: Keeping grain, feed, and fertilizer completely dry and contained
• Landscaping & Excavation: Preventing fine topsoil or sand from blowing out over the side rails
• Environmental Hauling: Containing contaminated soils or hazardous materials with zero side spillage
• General Freight: Any application where the customer requires the load to arrive fully contained and dry

The 9-foot width and 18-foot length make this tarp ideal for standard tandem-axle dump trucks with bodies in the 16–18 foot range. The 6" pocket and spline system ensure compatibility with the majority of electric and manual tarp systems currently in service.

How the Front-to-Rear Tarp System Works

Front-to-rear (F/S) tarp systems mount a cylindrical spool housing at the front of the dump body, near the cab. When deployed, the tarp unrolls from the spool and is carried rearward by aluminum arms that pivot from the sides of the dump body. The arms extend toward the rear of the truck, pulling the tarp taut over the entire load from front to back. The 6" rear pocket engages the spool at the front, and the spline on the front edge of the tarp locks into the tarp bar to maintain tension.

With this side flap model, once the tarp is fully deployed, the side flaps with shock cord hang down over the top edges of the dump body walls. The shock cord hooks to the body, pulling the flaps snug for a complete seal on all sides. This tarp is designed as a direct drop-in replacement for most front-to-rear systems.

Vinyl vs. Mesh Tarp Materials

Choosing between vinyl and mesh comes down to what you are hauling. If you are hauling rock, gravel, or demolition debris where the only goal is keeping the material in the truck, a Black Mesh tarp is lighter and easier to handle. However, if you haul asphalt, grain, or fine topsoil, water is your enemy — and side spillage is a compliance risk. The 18 oz. vinyl tarp with side flaps and shock cord provides the absolute waterproof barrier and complete side containment required for these specialized loads.

For extreme high-temperature asphalt hauling, you may also consider the Asphalt Lumite tarp, which is heat-resistant up to 350°F, though it is not 100% waterproof like this vinyl option.

Frequently Asked Questions

What do the side flaps do?
The side flaps are panels of 18 oz. black vinyl that extend downward from the long side hems of the tarp. When the tarp is deployed, the flaps hang over the top edges of the dump body walls, covering the gap between the tarp and the side rails. The shock cord sewn into the bottom of each flap hooks to the truck body to hold the flaps firmly in place at highway speeds, preventing material from escaping over the sides.

Will this tarp fit my dump truck?
This tarp is 9 feet wide and 18 feet long and is designed for standard tandem-axle dump trucks with a body length in the 16–18 foot range. The 6" pocket and spline system are compatible with most electric and manual front-to-rear tarp systems. If you're unsure, measure your existing tarp or contact DeBrovys for fitment assistance.

Is this tarp completely waterproof?
Yes. The 18 oz. vinyl-coated polyester is 100% waterproof and will keep your load completely dry, provided the tarp is deployed tightly and covers the entire load. The side flaps with shock cord further seal the sides to prevent water intrusion from the edges.

What makes the seatbelt webbing on this tarp better?
This tarp uses #6000 2" automotive-grade seatbelt webbing — the same material used in vehicle safety restraints. Most competitor tarps use 500 lb. 2" webbing, which is significantly weaker. The automotive-grade webbing resists tearing, fraying, and UV degradation far better than standard webbing, keeping your tarp secure at highway speeds.
