Cargo Bar vs Cargo Net vs Ratchet Strap: Choosing the Right Restraint

Three Tools, Three Purposes

Cargo bars, cargo nets, and ratchet straps are the three most common cargo restraint tools used in enclosed trailers, box trucks, and cargo vans. Each excels in different scenarios, and experienced drivers carry all three. Understanding when to use each — and when to combine them — is the key to efficient, secure cargo management.

Quick Comparison

Feature	Cargo Bar	Cargo Net	Ratchet Strap
Primary function	Prevent forward/rearward movement	Contain multiple loose items	Secure individual items to anchor points
Restraint direction	One direction (longitudinal)	All directions (containment)	Specific directions (adjustable)
Rated capacity	100-500 lbs (most models)	200-5,000 lbs (varies widely)	1,000-5,000+ lbs WLL
Setup time	5 seconds	30-60 seconds	30-60 seconds per strap
Cost	$15-$50	$20-$200	$10-$50 per strap
Weight	3-8 lbs	2-15 lbs	2-5 lbs per strap
Reusability	Excellent	Good	Good (inspect regularly)

Cargo Bars — When to Use

Cargo bars (also called load bars, decking bars, or shoring bars) are telescoping steel or aluminum tubes with rubber-padded ends that wedge between trailer walls to create a barrier against cargo movement.

Best Applications

• Palletized freight: A cargo bar behind a row of pallets prevents them from tipping or sliding toward the rear doors
• Partial loads: When the trailer is half-full, cargo bars divide the loaded section from empty space
• Supplemental restraint: Used with straps to provide blocking and bracing
• Quick adjustability: Easy to reposition as cargo is loaded and unloaded during multi-stop routes

Limitations

• Low rated capacity (most are 100-500 lbs) — NOT sufficient as sole restraint for heavy cargo
• Only restrain in one direction — cargo can move laterally around them
• Can slip if trailer walls are smooth or damaged
• Can bend or collapse if overloaded

Cargo Nets — When to Use

Best Applications

• Multiple small items: Boxes, bags, cases that would each need individual strapping
• Irregularly shaped items: Items that straps can’t grip effectively
• Rear door containment: Prevents items from falling out when doors are opened
• Supplemental containment: Used over strapped cargo to catch anything that shifts

Limitations

• Many consumer nets have no rated WLL — not DOT compliant as sole restraint
• Cannot apply precise tension to individual items
• Items can shift within the net if not packed tightly

Ratchet Straps — When to Use

Best Applications

• Individual heavy items: Machinery, appliances, furniture
• DOT-compliant securement: Rated WLL, meets FMCSA requirements
• Precise tension control: Ratchet mechanism allows exact tensioning
• Multi-directional restraint: Can be angled to restrain in any direction

Combination Strategies

Scenario	Recommended Combination
Full pallet load, multi-stop	Cargo bars between pallet rows + 2 straps per pallet
Mixed freight (pallets + loose boxes)	Straps on pallets + cargo net over loose items
Single heavy item (appliance)	4 ratchet straps (one per corner) + cargo bar behind
Partial load, loose items	Cargo bar as partition + cargo net over items + strap over net
Furniture delivery	Straps on each piece + blanket padding + cargo bar as separator

Common Mistakes to Avoid

Avoiding these common errors can prevent equipment failure, regulatory violations, and serious safety incidents in the field.

• Insufficient Aggregate WLL: FMCSA requires total WLL of all tie-downs to equal at least 50% of cargo weight. For a 40,000 lb load, you need at least 20,000 lbs of total tie-down WLL, which could be 10 ratchet straps rated at 2,000 lbs each.
• Relying Solely on Friction: While friction helps (rubber mats provide coefficient of 0.6-0.7), it cannot be the only securement. FMCSA requires positive securement devices in addition to friction to prevent cargo movement during emergency maneuvers.
• Not Securing Against All Directions: Cargo must be secured against forward, rearward, lateral, and vertical movement. Many drivers only secure against forward movement. Use a combination of direct tie-downs and blocking or bracing to prevent movement in all four directions.
• Wrong Securement for Cylindrical Loads: Coils, pipes, and drums require specialized methods per FMCSA 393.120. They cannot be secured like boxed cargo. Coils must use at minimum one tie-down per coil for eye-up positioning, or specific blocking arrangements for other positions.
• Failing to Re-Check Tie-Downs: FMCSA requires inspection within the first 50 miles and every 3 hours or 150 miles thereafter. Straps loosen due to load settling, vibration, and temperature changes. A tight strap at departure can be dangerously loose after 100 miles.
