Nailed vs plywood vs glued reels

Three builds cover most wooden cable reels in North American yards. They look alike at a distance, but they have very different futures, and take-back programs sort them before they look at anything else.

Nailed solid wood

Southwire's packaging chart describes its "all wood" reel exactly: flanges of two plies of boards, nailed together with the layers at 90 degrees. The drum is a ring of wooden staves around the hub, and on heavier reels a pressed-in steel hub lines the arbor hole. These are the reels for medium and heavy loads. In Southwire's chart they run from the 23 in C-1 to the 68 in A-99, whose empty weight is listed at 536.2 lb.

How to spot it: the flange edge shows two layers of separate boards, one running each way, with rows of nail or clinch heads across the face.

Where it goes: this is the reel that manufacturer programs and reel buyers want. Service Wire, AFL and Prysmian's programs are all for nailed or solid wooden reels, subject to size and condition. A sound nailed reel in a common size can go back into service after a refurbisher replaces any broken boards.

Plywood

Southwire's plywood reels have flanges cut from plywood sheet, with drums of fiberboard tube (its G series) or wooden staves (its N series). They carry lighter loads: covered and insulated conductor, and building wire. Many of the small reels and spools on an electrical job are plywood, such as the 23.75 in N-5 or the 11.75 in G-series spools.

How to spot it: the flange is one sheet, and its edge shows thin laminations. Larger plywood reels may have only a few bolts or nails through the flange into the drum.

Where it goes: AFL's program says no plywood reels are recyclable through it. Sound plywood reels can still have a second use, but they are a harder sell. Weathered plywood delaminates, and a split flange can't be re-boarded. Most end-of-life plywood reels go to wood recycling. Plywood contains glue, so ask your recycler first.

Glued or laminated

Some reels and spools are glued rather than nailed: laminated flanges, or a flange glued to a fiber drum. They are built to be used once. No program we list accepts them, and few buyers want them. They go to wood recycling with the plywood.

Thirty-second check in the yard

1. Look at the flange edge: separate crossing boards (nailed) or one laminated sheet (plywood or glued)?
2. Look at the face: rows of nail heads, or few or none?
3. Look at the drum: wooden staves, or a fiber tube?
4. Note the condition: rot, split boards, warped flanges, or torn-out drive holes all fail inspection.
