The easiest way to hold bulk spools to load fishing reels. Machined out of aircraft aluminum and then anodized, it holds spools from 1/4 lb through 5 lbs.
The unique design allows you to set the tension on the spool for smooth, constant pressure while loading. Bolt it to a work bench or use it in a rod holder with optional gimbal mount.
