Construction cones are the most-bought, most-replaced, and most-overlooked piece of traffic-control gear. A small NJ subcontractor buys 100–200 cones in their first year and replaces 15–20% annually. Get the spec wrong and you fail your first state inspection; over-spec and you spend twice what you needed. Below is the complete buying playbook — every spec choice, every accessory, every quantity tier — written for contractors who do not have a procurement team.

1. Pick a size before anything else

Cone height is set by the MUTCD based on road speed and time of day. Wrong height = inspection failure, full stop.

HeightDay useNight useBest for
12 inIndoor onlyNoWarehouse hazard marking
18 in≤25 mphNoParking lots, valet, low-speed
28 in≤55 mph≤35 mphGeneral roadway work
36 inAny speedAny speedHigh-speed and night work

2. Reflective collar grade

Federal MUTCD specifies ASTM Type IV high-intensity prismatic sheeting as the minimum for collars on roadway cones. Avoid anything sold as "Engineer Grade" (Type I) or "Super Engineer Grade" (Type II) — those grades are intended for stationary signage, not channelizing devices.

  • Single 4-in collar: OK for roads ≤35 mph during day. Cheapest legal option.
  • Single 6-in collar: OK for roads ≤35 mph day or night. Pay the small upcharge.
  • Double collar (4 + 6 in): Required for roads >35 mph. The contractor default.
  • Diamond-grade fluorescent: Roughly 2x the brightness of Type IV at the same distance. Worth the $3–4/cone upcharge if your crew does a lot of overnight or low-visibility work.

3. Base weight and shape

Base weight is the spec that decides whether your cones stay upright when a tractor-trailer passes at 65 mph. Light bases save you on shipping but cost you cones every week.

  • 4 lb base: Indoor and event use only. Will blow over on a roadway.
  • 7 lb base: Practical minimum for any roadway. Works for ≤35 mph.
  • 10 lb base: Highway-rated. The most common contractor spec.
  • 12+ lb base: Bridge decks, exposed-corridor highway, very-high-speed work.

Stackable bases save storage space — a stack of 50 stackable 28-inch cones takes about 3.5 feet of vertical truck space. Look for "stackable" or "nestable" in the spec sheet.

4. Material: PVC vs. TPE rubber

Most cones sold in the US are PVC. The premium upgrade is TPE rubber (thermoplastic elastomer). Differences:

PropertyVirgin PVCTPE rubber
Cost per 28-in cone$14–18$22–28
Cold toleranceCracks below 10°FFlexes to -20°F
Run-over behaviorCracks or breaksPops back up
Expected lifespan3–4 years5–7 years
Color durabilityFades 2–4 yrsFades 4–6 yrs

For any crew working near live traffic, TPE pays for itself within 18 months on cones-not-replaced.

5. Accessories worth buying with the cones

Order these in the same PO — shipping a single cone bar later costs more than the bar itself.

  • Cone bars (retro-reflective). 4-ft or 6-ft bars that snap between two cones. Useful for pedestrian channelization or marking a blocked sidewalk. $9–14 each.
  • Cone-mount lights. Battery LED flashers for nighttime. Pick steady-burn for tapers, flashing for hazard markers. $14–28 each. See our cone lights guide for models that survive the abuse.
  • Cone-mounted signs. "ROAD WORK AHEAD," "FLAGGER," "SIDEWALK CLOSED" plates that slot onto the cone tip. Lighter than full sign stands but only visible at short range. $18–30 each.
  • Storage rack. Wall or truck-bed mount that holds 20–50 cones vertical and dry. $80–200 depending on capacity.
  • Replacement bases. Don't throw out a cracked-base cone. Buy 10% spare bases per order. ~$5–8 each.

6. Bulk pricing tiers (Central NJ, 2026)

Per-cone price drops at 25, 100, and 250 unit thresholds. Order to the threshold if you are within 5 cones — the discount is bigger than the cost of the extra units.

Quantity28-in double-collar36-in double-collar
1–24$23–26$36–42
25–99$20–23$32–36
100–249$18–20$28–32
250+$16–18$24–28

7. Delivery and lead time

Three lanes for getting cones on a job site:

  • National distributor: lowest sticker, 5–10 business day lead time, freight surcharges. Use only when you have a long planning runway.
  • Regional supplier (mid-Atlantic): 1–3 day delivery, mid pricing, smaller minimum orders. The sweet spot for repeat buyers.
  • Local same-day: premium price, no lead time. Best for emergencies and small top-up orders.

We deliver Central NJ same-day on all standard 28-in and 36-in cones. Submit a quote before noon, get it on site the same afternoon.

8. Storage and inventory management

A cone left outdoors for two summers loses about 25% of its fluorescent intensity. Stack cones upright, indoors or under cover, base-down, in a cone rack. Don't stack horizontal — the cone walls flatten and the collars warp.

Inventory the cones at the start and end of every season. Retire any cone with: visibly faded orange, peeled or cracked reflective sheeting, cracked body, or a base that no longer sits flat. A retired cone can still serve in your yard for parking spots, just not on a roadway.

9. Bigger work zones need more than cones

Cones channelize. They do not protect. If you need physical separation between traffic and a work crew on foot, scale up to:

10. What to skip

Marketing the cone industry would like you to pay for and what is actually worth it:

  • Skip: "smart" cones with Bluetooth telemetry. The use case for a small contractor does not exist yet.
  • Skip: color-matched custom plastic (non-orange). Custom imprint on the collar is fine; non-orange body is not MUTCD-compliant.
  • Skip: "theft-resistant" cones. A sharpie and your DOT number does the same job.
  • Worth it: TPE rubber upgrade, double-collar spec, 10-lb bases, cone-mount lights for night work.

Where to start

For most new Central NJ contractors, the right first order is 50 × 28-inch double-collar TPE cones with 10-lb bases, plus 12 × 36-inch for higher-speed jobs, plus 12 cone-mount lights and a truck-bed rack. That puts you legal on every standard NJDOT job and runs around $2,000–2,500 delivered.
