- A strip of material that may be used to unitize articles and is tensioned and clamped or crimped back upon itself. (same as "Strapping")
- A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.
- A combination of securing devices which form an assembly that attaches cargo to, or restrains cargo on, a vehicle or trailer, and is attached to anchor point(s).

From The CDL Manual
Tiedown:
A combination of securing devices which form an assembly that attaches cargo to, or restrains cargo on, a vehicle or trailer, and is attached to anchor point(s).
- It is packed in a square box.
- It is loaded on the end of the truck.
- it fills a sided vehicle, and every article is in contact with or sufficiently close to a wall or other articles so that it cannot shift or tip if those other articles are also unable to shift or tip.
- It fills a void between articles of cargo and the structure of the vehicle that has sufficient strength to prevent movement of the articles of cargo.
From The CDL Manual
Contained:
Cargo is contained if it fills a sided vehicle, and every article is in contact with or sufficiently close to a wall or other articles so that it cannot shift or tip if those other articles are also unable to shift or tip.
- A vertical barrier across the front of the deck of a vehicle to prevent forward movement of cargo.
- A tapered or wedge-shaped piece used to secure round articles against rolling.
- A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.
- A rail along the side of a vehicle that protects the side of the vehicle from impacts.
From The CDL Manual
Blocking:
A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.
- 28,784 lbs
- 17,990 lbs
- 10,000 lbs
- 36,000 lbs
From The CDL Manual
Note: If the cargo is contained in a sided vehicle, the vehicle structure MUST be strong enough to withstand the forces described earlier.
- Forward force: 0.8 g (80%)
- Rearward force: 0.5.g (50%)
- Sideways force: 0.5 g (50%)
- Void filler.
- A chock.
- A cleat.
- A friction mat.
From The CDL Manual
Friction mat:
A device placed between the deck of a vehicle and car or between articles of cargo, intended to provide greater friction than exists naturally between these surfaces.
- The summation of the working load limits or restraining capacity of all devices used to secure an article on a vehicle.
- A combination of securing devices which form an assembly that attaches cargo to, or restrains cargo on, a vehicle or trailer, and is attached to anchor point(s).
- The maximum weight of a load of rocks that a securement device can withstand.
- The maximum load that may be applied to a component of a cargo securement system during normal service, usually assigned by the manufacturer of the component.
From The CDL Manual
Aggregate Working Load Limit:
The summation of the working load limits or restraining capacity of all devices used to secure an article on a vehicle.
- A device placed between the deck of a vehicle and car or between articles of cargo, intended to provide greater friction than exists naturally between these surfaces.
- A strip of material that may be used to unitize articles and is tensioned and clamped or crimped back upon itself. (same as "Strapping")
- A platform or tray on which cargo is placed so that it can be handled as an article. (Same as "Skid")
- A rail along the side of a vehicle that protects the side of the vehicle from impacts.
From The CDL Manual
Rub Rail:
A rail along the side of a vehicle that protects the side of the vehicle from impacts.
- The maximum load that may be applied to a component of a cargo securement system during normal service, usually assigned by the manufacturer of the component.
- The acceleration due to gravity, 9.823 m/sec2 (32.2 ft/sec2).
- The summation of the working load limits or restraining capacity of all devices used to secure an article on a vehicle.
- The number of hours that a tiedown can be used.
From The CDL Manual
Working Load Limit (WLL):
The maximum load that may be applied to a component of a cargo securement system during normal service, usually assigned by the manufacturer of the component.
- 6,000 lbs
- 2,500 lbs
- 10,000 lbs
- 5,000 lbs
From The CDL Manual
Note: The minimum WLL requirement for the securement system is 50%. More tiedown capacity should be used if you need to secure an article against any movement.
- Void filler
- Stake pocket
- Cleat
- Bulkhead
From The CDL Manual
Stake Pocket:
A female housing fixed to the side or ends of a vehicle to receive a stake or peg, and may also be used as an anchor point.
