Cable Tie Size Chart: Length, Tensile Strength and Bundle Diameter

Updated September 3, 20264 to 48 in lengths120 stocked ties

Cable ties are sized by length and rated tensile strength: an 8 inch tie closes a 2 inch bundle, an 11 inch tie a 3 inch bundle, and 50 lb is the standard class for general use with 120 lb and up for heavy or outdoor work. The chart converts length to the largest bundle each tie holds, explains the tensile classes and strap widths, and lists every stocked nylon tie by length, strength, variant and cost per tie.

Size chart: length to bundle diameter

A cable tie is named by its overall length and its rated tensile strength. Length sets the largest bundle the tie can close, because the strap has to go all the way around and leave enough tail to grip in the head. The rule is simple: subtract about an inch and a half for the head and the minimum tail, then divide by pi. An 8 inch tie therefore closes a bundle about 2 inches across; an 11 inch tie about 3 inches.

Usable bundle diameter is roughly (length minus 1.5 in for head and tail) divided by pi.
Length Max bundle (approx.) What it wraps
4 in 0.9 in Two or three wires, a bag neck
5.5 in 1.2 in Small harness, drip line
7.5 in 1.8 in 1 in conduit, garden hose
8 in 2.0 in Coax bundle, small pipe
11 in 3.0 in 3 in duct, large harness, sign to post
14 in 4.0 in 4 in pipe, rolled film
15 in 4.0 in Same as 14 in with more tail
18 in 5.0 in Mesh panels, fence, 5 in duct
24 in 7.0 in Pallet strapping of light loads, bundled tubing
36 in 10.0 in Large drums, poles
48 in 13.0 in Wrapping bales, large cylinders

Tensile strength classes

Tensile is the minimum loop tensile strength (UL 62275 / MS3367 classes). Choose a class at least 20 percent above the load the tie must hold, and derate 20 to 40 percent outdoors or at temperature extremes.
Tensile class Rated loop strength Strap width Typical use
Miniature 18 lb 0.09 in Wire harness branches, tags, light bundling under 3/4 in
Intermediate 40 lb 0.14 in Small cable bundles, packaging, garden and light fixture work
Standard 50 lb 0.18 in The general-purpose tie: cable runs, hose, bag necks, pallet strapping of light loads
Heavy duty 120 lb 0.30 in Conduit, large harnesses, securing product to pallets and racks
Extra heavy duty 175 to 250 lb 0.35 to 0.50 in Fencing, signs, mesh, outdoor structures, anything that vibrates

Stocked cable ties

Natural (white) nylon 6/6 is the indoor standard; black UV stabilized nylon is for anything in sunlight, where plain nylon turns brittle in a season; releasable ties have a thumb tab so the bundle can be opened and re-closed; colored ties are for coding runs. Per-tie cost falls steeply with case count, so a 1,000 case of 50 lb ties is usually the right buy for a packing bench.

Choosing a tie

  1. Measure the bundle. Wrap a tape around the largest bundle the tie will see and add 25 percent for growth; pick the length whose max bundle covers it.
  2. Pick the class. Match tensile to the load with a 20 percent margin; for suspended loads or anything that moves, step up a class.
  3. Match the environment. UV stabilized outdoors, heat stabilized near engines or ovens, stainless steel where chemicals or flame are involved.
  4. Consider removal. Releasable ties where the bundle will be opened; standard ties are cut off.
  5. Trim flush. Cut tails with a flush cutter or tensioning tool; an angled cut leaves a sharp edge that slices hands and cable jackets.

Cable ties in packaging

On a packing line, ties close the necks of large poly bags and liners, bundle rolled goods, secure loose parts to a pallet through the stringers, and hold corner boards under stretch film. A 50 lb 11 inch tie handles nearly all of these; the pallet sizes chart and stretch film gauge chart cover the rest of the load-securing kit, and the poly bag thickness guide pairs bag mil with the tie that will not cut it.

Frequently asked questions

What size cable tie do I need?

Measure the bundle diameter, add about 25 percent, then multiply by pi and add 1.5 inches: a 2 inch bundle needs an 8 inch tie, a 3 inch bundle an 11 inch tie. Pick the tensile class at least 20 percent above the load.

What does 50 lb mean on a cable tie?

The minimum loop tensile strength, the pull the closed loop holds before the head or strap fails. 50 lb is the standard general-purpose class with a strap about 0.18 inch wide.

What is the difference between natural and black cable ties?

Natural nylon is uncolored and for indoor use; black ties are UV stabilized with carbon black for sunlight exposure. Plain nylon outdoors goes brittle within a year.

How big a bundle does a 14 inch cable tie hold?

About 4 inches in diameter, and a 24 inch tie about 7 inches. The usable strap is the length minus roughly 1.5 inches for head and tail.

Are cable ties reusable?

Standard ties are single use and are cut off. Releasable ties have a tab that lifts the locking pawl so the strap can be pulled back out and re-tightened.
