30-inch cable reels: the first size the maker programs accept

On the line, not over it

AFL’s published standard reads “not less than 30 inches in diameter”, and Service Wire’s return guidelines give a 30 to 72 inch range. A sound 30-inch nailed reel therefore meets the size rule. It still has to clear the rest: flanges at least 1½ inches thick, no torn drive hole, about three-quarters of the staves intact, no cable left on it. And it has to travel with a full truckload, which at this size is a lot of reels. Sonoco’s own load table does not even list anything smaller than 36 inches.

In practice a yard in Beltsville or Chantilly with a dozen 30-inch reels has reels that qualify one by one and fail as a load. That is the gap the desk covers.

What it carries

The A-10 and A-11 belong to Southwire’s A series, nailed reels designed for bare aluminium and ACSR conductor; the N-7 and N-11 are its lighter N-series nailed designs for insulated and multiplex products. On a job site, a 30-inch reel is often service drop or secondary cable, or a shorter run of feeder.

Handling

Fifty to sixty-six pounds is still a one-person reel on flat ground, but carrying one any distance is a two-person job. Roll it on its flanges in the direction the arrow on the flange points, and never off the tailgate: a 30-inch flange cracks along the board joint if it lands on its edge.

What it suits once empty

Stood on end, an A-10 is 25 inches high with a 30-inch top, a little low for dining and right for a sturdy coffee table or a bench-side table on a patio. Gardeners use them for hose. Contractors who wind their own short lengths of wire like this size because it fits a standard reel stand and a pickup bed.

Tell the desk the reel number on the tag if it is still there (A-10, N-7 and so on); it saves a tape measure and tells us the drum.

Published dimensions at and near 30 inches

Southwire lists three reels at 30 inches and one at 31. All four are nailed wood with the standard 3⅛-inch arbor hole.

Reading the numbers

Flange

The diameter of the round end, edge to edge. The size a reel is known by.

Traverse

The inside width between the flanges, where cable winds. It sets how tall the reel stands on end.

Drum

The diameter of the barrel the cable winds onto. Stiff power cable needs a big drum.

Arbor hole

The centre hole for a shaft. 3⅛ in on most wooden reels; 5¼ in and up on heavy steel ones.

Weight

Empty, or tare, weight in pounds as the maker publishes it. A tag on the reel gives the same figure.

Series letter

Southwire codes the build: A and C nailed, N plywood or nailed, E and G plywood, S steel.

Where 30s turn up here

Service drop and secondary cable for new subdivisions in Charles and southern Prince George’s, and short feeder runs on commercial jobs in Montgomery. Before you count a 30 toward a take-back load, check the flange thickness at the rim with a tape: AFL wants 1½ inches, and some lighter reels at this size come in under it. Thin flanges are no problem for the desk.

Requests for 30-inch reels

Selling or clearing

A sound nailed 30-inch reel meets the size rules of the programs we have read; count by brand first in case one maker's reels fill a truck. Send the desk the rest.

Buying

Say whether it is for a table, a hose winder or re-spooling, and the height you need on end.

Empty weight to plan for
