Flatbed Straps

Endless Ratchet Straps Buying Guide

Winch strap or ratchet strap, and why flatbeds run both. The two families here tension the same webbing in different ways. A winch strap has a hook on one end and a clean sealed tail on the other; the tail feeds through a winch bolted or welded to the trailer, and you crank the mandrel with a winch bar to pull the load down. A ratchet strap has a ratchet buckle in the run that you pump by hand, and a hook on each end. Flatbeds favor winch straps for long hauls of steel, pipe, and lumber because the winch stays mounted on the rail and the strap stores wound on the mandrel, ready to throw. Ratchet straps go where there is no winch, anchoring over D-rings and rub rails. Kinedyne's 2 inch flat hook winch strap runs about $16, and the 2 inch wire hook ratchet strap with a StrapPak sleeve to stow the loose tail is near $50. Both styles are hooked securement, which is what separates this collection from loop-style tie-downs that have no fitting at all.

Match the hook to the trailer, not the load. The webbing is the same polyester across the line; the end fitting decides whether the strap works on your equipment. Flat hooks are genuinely flat and grab a flatbed rub rail or drop into a stake pocket, which makes them the freight default in 2, 3, and 4 inch. Wire hooks are slimmer, sized for stake pockets and rails that flat hooks have worn loose, with the 2 inch narrow wire hook winch strap around $18. Chain anchors end in a short length of chain for machinery tie-downs and anchor points webbing cannot reach, near $28.69 in 2 inch and about $32 in 3 inch. Delta rings finish drop-deck and winch systems and appear on the 3 and 4 inch builds. Pick the fitting for the rail, pocket, or anchor you actually have on the trailer, then choose the width and rating separately, because the hook does not change the strength.

Width and webbing set the rating. Rating climbs with width and webbing line. Two inch is general freight at 3,335 lb standard, around $16 for the flat hook winch strap. Above it the abrasion-resistant lines carry more and shrug off the friction that retires most straps early: K-FORCE and Rhino MAX both push 2 inch to 4,000 lb, with the K-FORCE flat hook ratchet strap near $32 and the Rhino MAX flat hook around $39. Three inch steps up to 5,400 lb for heavier machinery and coil, the flat hook winch strap about $22. Four inch is steel and equipment territory: the standard flat hook winch strap holds 5,400 lb, while the 4 inch K-FORCE flat hook reaches 6,670 lb near $23 and the 4 inch wire hook ratchet strap carries the same 6,670 lb around $92. Every rating is assigned under the WSTDA standard, which caps the working load limit at no more than one third of the assembly break strength, so a 3,335 lb tag sits on 10,000 lb webbing. That reserve absorbs shock and wear and is not capacity to spend.

The winch is half the system. On a winch-strap trailer the strap is only as strong as the winch it winds onto, so the winches live here too. Weld-on winches fix permanently to the frame and rate up to 6,670 lb, around $31, the right pick where strap positions never change. Portable winches clamp to the rail with two set screws and move anywhere along it, near $29.59 at 5,500 lb, good for occasional use and mixed loads. Sliding winches ride a C-channel or double-L track so you slide the anchor to wherever the load sits, with the standard sliding C-channel winch about $66 at 5,500 lb. Kinedyne also builds low-profile, undermount, bolt-on, and cable versions of each for tighter clearances and specific frames. Match the winch working load limit to the strap it tensions, and pick the mounting style by how your frame is set up: fixed positions weld on, variable loads slide, light or shared duty goes portable.

Protect the webbing and keep the tag readable. Two things end a flatbed strap early, and the accessories here answer both. Abrasion is the first: a nylon protective sleeve slides over the webbing where it crosses a sharp steel edge or a coil, from about $5.63 in 2 inch up through the 3 and 4 inch sizes, and a few dollars of sleeve saves a strap that costs many times more to replace. A missing rating is the second: FMCSA rates an unmarked tiedown down to a federal default value well below what a marked strap actually carries, so keep the stenciled working load limit legible and retire any strap you cannot read. The reflective VeeBoard near $12.75 improves visibility on wide and projecting loads, and a 1 inch cam-buckle boat safety strap rounds out the light-duty end. The half-weight math and minimum tie-down count that decide how many straps a load needs live on the parent ratchet straps page; this collection is about picking the right hooked strap and the winch that pulls it tight.
