How to Choose a Ratchet Strap

A ratchet strap has four choices to get right: width, length, end fitting, and strength rating. This guide covers each one, with real straps from Boxer Tools as examples. Browse the full range in Ratchet Straps & Tie-Downs.

Strap width and what each width is for

Wider webbing spreads the load over more material, so wider straps carry higher ratings.

• 1 inch — light loads: motorcycles, ATVs, UTVs, bikes, and small gear on a utility trailer. See 1" Tie-Down Straps.
• 2 inch — the general-purpose size: the standard flatbed and trailer width. See 2" Tie-Down Straps.
• 3 inch — heavy equipment and machinery: for construction materials and industrial loads. See 3" Tie-Down Straps.
• 4 inch — the heaviest flatbed loads: large machinery and oversized equipment. See 4" Tie-Down Straps.

Width alone does not set the rating — two 2-inch straps can have different ratings — so check the working load limit on the listing, not just the width.

* 4-inch WLL is from the matching 4" x 18" short-end strap (same 16,200 lb break strength, 5,400 lb WLL).

Length: how to measure what you need

Measure anchor to anchor along the path the strap will take over the load. Then add length for the strap to wrap around the ratchet spool — a strap that only just reaches will not tighten properly. Common lengths are 9 ft for 1-inch straps, 16 ft to 30 ft for 2-inch straps, and 27 ft to 30 ft for 3-inch and 4-inch straps. If you are between lengths, go longer — extra webbing can be secured out of the way, but a strap that is too short cannot be made to reach.

End fittings and which anchor each suits

Match the fitting to the anchor point you have.

• Flat hooks — over a rub rail, stake pocket edge, or flat anchor point on a flatbed or trailer. See Flat Hooks.
• Wire hooks / twin J hooks — J-shaped hooks that catch frame openings, D-rings, and small anchor points. See Wire Hooks.
• Chain ends (Grade 70 chain hooks) — for heavy loads and anchors where a hook would not seat well. Example: the 2" ratchet strap with G70 forged chain hooks (10,000 lb break strength).
• E-track fittings — snap into E-track rails and slide along the track to sit where the load is. Example: the 2" x 8' E-Track Idler Car Tie Down Kit (3,300 lb break strength, 1,100 lb working load limit). See E Track Straps.
• Twist snap hooks and flat snap hooks — hooks with a latch or twist closure that stay shut if the strap goes slack, suited to vehicle transport. Example: the 2" ratchet strap with twist snap hooks (10,000 lb break strength, 3,330 lb working load limit).

If your trailer has no matching anchor for the fitting you are considering, the fitting is wrong for that trailer — change the fitting, not the anchor.

Working load limit vs. break strength

Every strap lists two strength numbers. Break strength is the load at which the strap is expected to fail in testing. Working load limit (WLL) is the maximum load it should carry in normal use — the number to plan around.

Here, the working load limit is one-third of the break strength, a 3:1 ratio. One live example: the 2" x 8' E-Track Idler Car Tie Down Kit lists a 3,300 lb break strength and a 1,100 lb working load limit (3,300 ÷ 3 = 1,100).

Never plan a load against break strength: if your load weighs 1,500 lb, a strap with a 1,500 lb break strength is not enough. You need one whose working load limit covers the load.

When to step up a size

• The load is close to the working load limit. Past about two-thirds of a strap's working load limit, step up a width or add a second strap.
• The load can shift. Tall, top-heavy, or round loads move more in transit than low, flat ones.
• The span is long. A longer span means more strap to tension — use the next length up and the next strength up together.
• The fitting does not seat fully. A hook that only just catches an anchor point is a reason to change fitting type, for example from a wire hook to a flat hook or chain end.

Checklist: before you buy

• [ ] Know the weight of the load each strap will carry.
• [ ] Pick a width whose working load limit covers that weight.
• [ ] Measure anchor to anchor, then add length for the ratchet spool.
• [ ] Match the end fitting to the anchor points on your trailer or truck.
• [ ] Check the working load limit, not the break strength, against your load.

FAQ

What size ratchet strap do I need? Match the working load limit to the weight the strap will carry: 1-inch straps suit motorcycles and ATVs (1,000 lb), 2-inch straps suit general trailer and flatbed loads (1,500 to 3,330 lb), and 3-inch and 4-inch straps suit heavy equipment (5,000 and 5,400 lb).

What is the difference between working load limit and break strength? Break strength is the load at which the strap is expected to fail. Working load limit is the maximum it should carry in normal use — one-third of the break strength on the straps in this guide. For example, the 2" x 8' E-Track Idler Car Tie Down Kit lists 3,300 lb break strength and a 1,100 lb working load limit.

How long should a ratchet strap be? Measure anchor to anchor over the load, then add extra for the ratchet spool. Common lengths are 9 ft (1-inch) and 16 ft to 30 ft (2-inch, 3-inch, and 4-inch). If you are between lengths, go longer.

What end fitting should I choose? Match it to your anchor point: flat hooks for rub rails and flatbed edges, wire or twin J hooks for frame openings and D-rings, chain ends for heavy loads and chain anchor points, and E-track fittings for E-track rails in an enclosed trailer. If the fitting does not seat fully, choose a different fitting.

Can I use a 2-inch strap instead of a 4-inch strap? Only if the 2-inch strap's working load limit covers the load. A 2-inch strap rated at 3,330 lb does not replace a 4-inch strap rated at 5,400 lb for a load that needs the higher rating.
