After more than a year without a way to keep your spools from dumping out the back if you tilt your U Series Bonsai Wire Condo, we have a solution. The U Series Spool Retainer Bar Set is super easy to use and only takes a second to remove or install. While this add-on is not necessary, it sure could save you from a mess.
Two models: U1K Model - Set of 2 - Made to fit Double Base models only. Will block six out of 9 for Triple Bases or you could use a single one on a single module. U1K-XL Model - Set of 2 - A little larger than the U1K model, otherwise the same.
