Chipboard tube & top wire spools, complete with metal spool plugs that have pre-stamped drive holes and locking anchors for a long lasting use.
These wire spools can be easily assembled in a moments time; insert the spool plug through the ID of a flange and pressed into a spiral wound paper tube. The end caps have locking anchors that hold the spools simply & securely.
These look well made. Unfortunately they were supplied with plastic core plugs, and not steel as pictured. I planned on using these for my high temperature 3d printer filament which needs dried in an oven. The plastic spools the 3d printer filament come on always melt and deform. These would have been perfect, but the plastic core plugs that were included will also melt just the same.
Easy to assemble. Some pointers on capacity of the small one, 100 ft of 22 AWG is not worth the effort to put it on as you use so little of the capacity. However 200 ft of 18 AWG makes good use of the capacity. Also 50 ft of the Ray Allen servo hookup wire (5 conductor) does a good job of filling one out. My only experience with the large size was 100 ft of 12 AWG and I think it would have been a better fit to the small size. I have all of my large quantity wire on these spools and have no regrets. I have only one minus and that there is no hole pre-drilled in the sides or tube to stick some wire in when starting to fill it but a minute with a drill will fix that.
