| This is probably the oldest automatic tarp system in the industry. Yes, it is the oldest in theory of how
it works, but it's the components which make this system get better and better with each year. There are many
different types of materials used between Mesh and Solid Vinyls, and the hardware that attaches to the truck
or trailer vary so much you need the experience of a knowledgeable manufacturer to help you pick the right
products for your application.
We would be happy to help you design the right product for your application. Please review the website to
compare hardware and materials so you are more confident with the products used for your system.
The tarp is attached to one side of the trailer and is rolled over the width of the trailer to the opposite
side. The tarp is held tightly in place.
|
- One system is held down with straps
- The other system is held down by rolling under an aluminum extrusion with a locking handle. More detail
is show in the parts & accessories section below.

| System Components |
| |
- Screws & Washers: The tarp is attached to the entire length of the
trailer by screwing through a re-enforced area along the edge of the tarp. On the same side of the trailer
Tarp Stops are installed to prevent the tarp from falling off the top of the trailer when the tarp is in
the "rolled up" or "stored" position.
- Pipe Assembly: A 3/4" galvanized pipe is installed into a pocket
in the tarp that goes the length of the trailer. The pipe and tarp are bolted onto the side of the trailer
using pipe clips bolted to the side of the trailer. Tarp Stops are installed to prevent the tarp from falling
off the top of the trailer when the tarp is in the "rolled up" or "stored" position.
- Pipe Brackets: Brackets are bolted to the side of the trailer. The pipe
assembly fits into the brackets and is held in place. The pipe brackets typically have tarp stops incorporated
into them to prevent the tarp from falling off the top of the trailer when the tarp is in the "rolled
up" or "stored" position.

| A 2" aluminum pipe is installed in a pocket in the tarp. The pipe is long enough to extend past the length
of the tarp and is used to roll the tarp across the width of the trailer. The pipe has to be the right length
to avoid interfering with the trailer doors and keep the tarp from falling into the trailer. |
| |
- SUR-LOC: An extrusion is attached near the top of the trailer
(on the opposite side of the trailer that the tarp is mounted to) The tarp is rolled over the edge
of the trailer. When you continue to roll the tarp it binds into the extrusion and holds the tarp in
place. The handle must be held in a bracket to keep tension on the tarp to prevent tarp from rolling
out.
|
 |
- Ratchet Straps: The tarp is rolled over the edge of the trailer.
A combination of heavy 2" webbing straps, cables and ratchet straps are used to tension the tarp
down to prevent tarp from lifting.

| It is always important to prevent air from getting under the tarp. With a tall trailer it is even more important
because a loose tarp can get caught on a bridge and really screw up your day! Here are some methods we use. |
- Wind Deflector: A low profile wind deflector is welded or bolted
to the front of the trailer and the front of the tarp is positioned directly behind the deflector.
|
 |
- Partial Bonnet: A flap is incorporated into the front of the tarp.
This flap is tensioned over the front of the trailer using Bungee Cord and 2 ratchet straps.
