15” spool (about 7.5” inner spool to wrap around, with an internal width of 6”). Intended for a pro audio snake, this cable reel will work for just about anything you need to wind and has a comfortable carrying handle. It has a winding knob on the front and a locking brake on the back to keep it from unwinding on its own. It has a comfortable carrying handle and is built to handle a lot of weight. I also have a much larger spool; take a look at my other offers. $40. Shipping is only an additional $13.99 within the contiguous USA. If you make an offer, I will assume that you are picking it up as I will not accept less when shipping (because it will obviously cost more than $13.99 to ship). When shipping you must buy through OfferUp. Anyone else can pay cash/PayPal/Credit card through PayPal upon pickup.
