How to Thread a Ratchet Strap The Right Way Every Time
Threading a ratchet strap wrong is one of the most common mistakes haulers make. It costs you tension, wastes time on the side of the road, and puts your load at risk. Get it right once and you'll do it the same way every haul.
This guide covers the full process: opening the mandrel, feeding the strap, tensioning the load, and releasing it cleanly. It also covers what to check before you ever hook anything up.
Know Your Ratchet Strap Before You Thread It
Three components matter before you start threading:
- The ratchet mechanism — the toothed wheel and handle assembly that builds tension
- The mandrel — the slotted axle at the center of the ratchet where the strap feeds through
- The strap webbing — the flat polyester webbing doing the actual securing work
The hooks on each end anchor to your tie-down points or e-track fittings. The strap feeds through the mandrel and tightens as you work the handle.
Know your working load limit before you use any strap. A 4-inch by 35-foot winch strap rated at 5,400 lb SWL is not interchangeable with a lighter-duty strap just because it looks the same. Check the label.
Step-by-Step: How to Thread a Ratchet Strap
Step 1: Open the Ratchet
Open the ratchet handle all the way flat. This releases the pawl — the small locking tab that holds tension — and exposes the mandrel slot running straight through the center of the axle.
If there's webbing already wound in from a previous use, pull it out completely and start clean.
Step 2: Feed the Strap Through the Mandrel Slot
Hold the loose end of the webbing flat and straight. Feed it up through the bottom of the mandrel slot and pull it through until several inches are sticking out the top.
The strap needs to run flat with no twists. A twisted strap won't tension evenly and can damage the webbing under load. Take five extra seconds to straighten it before you move on.
Step 3: Hook Both Ends to Your Anchor Points
With the strap threaded, hook the fixed end to your anchor point first — trailer rail, e-track fitting, or tie-down ring. Then hook the ratchet end to its anchor point on the opposite side of the load.
Make sure both hooks are fully seated. A hook resting on the tip of a rail instead of fully engaged will slip under load.
Step 4: Pull Out the Slack
Before you start ratcheting, pull the loose tail by hand to remove as much slack as possible. The more you pull out manually, the tighter your final tension will be — and the less work the ratchet has to do.
Don't skip this. Starting with a lot of slack means you're winding excess webbing onto the mandrel instead of building real tension on the load.
Step 5: Ratchet to Tension
Close the handle and start pumping. Each stroke advances the mandrel and pulls the strap tighter. Keep going until the strap is firm and the load has no movement.
For vehicle transport, the suspension should be slightly compressed. For cargo, push on the load by hand — it shouldn't move.
Step 6: Lock the Ratchet
Once you have proper tension, leave the handle in the closed position. The pawl locks the mandrel and holds your tension. Don't leave the handle open — it will release under vibration.
Step 7: Secure the Tail
Loose webbing is a road hazard. Fold it and tuck it, or use tape or a bungee to keep it from flapping. A loose tail can catch wind, wrap around axles, or distract other drivers.
How to Release a Ratchet Strap
Releasing is where people break straps and ratchets by forcing them.
Find the release tab — usually a small lever or button near the pawl. Press or flip it while opening the handle. This disengages the pawl and lets the mandrel spin freely.
Open the handle all the way flat, then pull the strap tail to unwind it. Don't yank the strap sideways or try to force the ratchet open without releasing the pawl first. That's how you bend the mechanism.
If the strap is under heavy tension and the release tab won't move, try one more ratchet stroke to slightly increase tension. That often frees the pawl. This is normal.
Common Threading Mistakes to Avoid
Feeding the strap over the top of the mandrel instead of through the slot. The strap must go through the slot. Draped over the axle, it will pull free under load.
Leaving twists in the webbing. Twisted webbing concentrates stress on one edge and weakens the effective SWL. Feed it flat every time.
Not pulling out slack by hand first. Excess slack winds onto the mandrel and limits how much tension you can actually build.
Using a strap with a damaged or unreadable label. If you can't read the working load limit, you don't know what you're working with. Replace it.
Mixing strap widths and hardware sizes. A 2-inch strap on a 4-inch ratchet won't tension correctly. Match your hardware.
Choosing the Right Ratchet Strap for the Job
Width, length, and working load limit all matter. Not every strap is right for every haul.
| Strap Width | Typical SWL | Common Use |
|---|---|---|
| 1-inch | 833 lb | Light cargo, motorcycles |
| 2-inch | 3,333 lb | General cargo, ATVs |
| 3-inch | 5,000 lb | Heavier cargo, small vehicles |
| 4-inch | 5,400+ lb | Full vehicle transport, flatbed |
For vehicle transport, a 4-inch strap with a chain anchor — like the 4-inch by 35-foot winch strap rated at 5,400 lb SWL — gives you the length and rated capacity to work across most trailer configurations.

Ratchet Strap Care and Inspection
A strap that threads fine today can fail tomorrow if you're not checking it.
Before every haul, look at:
- Webbing condition — no cuts, fraying, or burn marks
- Hook condition — no cracks, bends, or missing safety latches
- Ratchet mechanism — pawl engages cleanly, handle moves without grinding
- Label legibility — SWL and strap grade must be readable
Retire any strap with visible webbing damage. A strap that's been cut, melted, or heavily abraded has lost working load limit integrity regardless of what the label says.
Store straps loosely coiled in a dry location. Don't leave them bunched under heavy equipment or sitting in direct sun for extended periods. Polyester webbing degrades with prolonged UV exposure.
FAQs
How do you thread a ratchet strap for the first time? Open the ratchet handle flat to expose the mandrel slot. Feed the strap webbing up through the slot from the bottom, keeping it flat with no twists. Pull several inches through, hook both ends to your anchor points, pull out the slack by hand, then ratchet to tension.
Which way does the strap feed through the ratchet? Feed it up through the bottom of the mandrel slot. The webbing should come out the top as you pull it through. That orientation lets the mandrel wind the strap correctly as you ratchet.
Why won't my ratchet strap tighten? Usually too much slack left in the strap before ratcheting. Pull the webbing tail by hand until the strap is snug against the load, then start ratcheting. If it still won't advance, check that the strap is seated in the mandrel slot and not just draped over the axle.
How tight should a ratchet strap be? Tight enough that the load can't shift. For vehicle transport, the suspension should be slightly compressed. For cargo, push on the load by hand — it shouldn't move. Don't over-tension to the point where the webbing looks visibly stressed or stretched thin.
How do you release a ratchet strap that's stuck under tension? Press the release tab while opening the handle all the way flat. If the tab won't move, add one more ratchet stroke to slightly increase tension — that often frees the pawl. Then press the release tab and open the handle. Never force the mechanism sideways.
Can you reuse a ratchet strap after it's been under heavy load? Yes, as long as the webbing, hooks, and ratchet mechanism pass a visual inspection. Check for cuts, fraying, hook deformation, and label legibility. If anything fails, replace the strap before the next haul.
What is the working load limit on a standard ratchet strap? It depends on strap width and construction. A 4-inch professional-grade winch strap can carry 5,400 lb SWL or more. Always check the label on your specific strap — working load limits vary significantly between consumer-grade and professional-grade webbing.
Threading a ratchet strap correctly takes about 60 seconds once you've done it a few times. The steps don't change. Open the ratchet, feed the strap flat through the mandrel slot, hook both ends, pull out the slack, ratchet to tension.
