500 Ft Cat6 Box: The Standard Half
Quick answer / TL;DR: Short answer: buy 500 ft Cat6 for measured requirements under about 130 m; above that, a 1000 ft box costs less per metre and avoids a joint. Pull the longest runs first, keep the box upright, and read the footage marker as you go. Store the remainder coiled at a large radius, out of sunlight.
A 500 ft Cat6 box is the unit for a small floor or a single-suite fit-out: 152 metres of 23 AWG solid cable, enough for fifteen drops with margin. It is the middle option between a patch-cord world and a full building reel, and it is where most small projects should start.
This is the 500 ft Cat6 guide: the arithmetic, the payout rules, and the threshold at which a 1000 ft box becomes the cheaper decision.
The Arithmetic
| The element | The allowance |
|---|---|
| Route measured | Horizontal plus vertical |
| Service loops | About a metre per end |
| Margin | Five to ten percent |
| Threshold | About 130 m per 500 ft box |
The threshold is where the box stops covering the job with margin and starts requiring a second box or a joint.
The Payout Discipline
- Pull through the payout hole, never off the side
- Keep the box upright and the hole clear
- Avoid sharp edges at the first bend
- Cut after the loop is formed, not before
The rules protect pair geometry: a twisted pair pulled sideways never untwists back to its manufactured state.
When to Step Up
| The situation | The choice |
|---|---|
| Under 130 m | 500 ft |
| 130-280 m | 1000 ft |
| Repeated small jobs | 500 ft per job |
| One long backbone run | Measure first – may exceed the channel |
The step-up decision is cost per metre against the risk of a joint; at scale the larger box usually wins.
Standards and Verification
| The reference | The relevance |
|---|---|
| TIA-568.2-D | Cable and installation practice |
| UL 444 | Jacket ratings |
| IEC 61156 | Cable construction |
| Field test | Channel test per run |

Real-World Applications
The single suite
A 120 m² office with fourteen drops: one 500 ft box, longest runs first, six metres spare for two future points.
The two-box job
A floor measured at 180 m: two 500 ft boxes ordered to avoid a 1000 ft reel, the second used across two phases – no joint, and no unused capital.
The stored remainder
Half a box left after a fit-out: coiled at a large radius and labelled with its length – usable a year later for a small addition.

Frequently Asked Questions
How many drops does 500 ft of Cat6 cover?
Roughly 12-15 depending on route, verticals and loops.
500 ft or 1000 ft?
500 ft under about 130 m measured; 1000 ft above.
Why pull the longest runs first?
So the remainder serves the short runs without a joint.
How should the remainder be stored?
Coiled at a large radius, out of sunlight, length marked.
