4D RO Tubing Holders

These tubing holders are a great way to organize all of the 1/4" tubing on your tank.  They are stackable to allow multiple tubes in a tight space.  For example if you only have enough space for a 4 tube holder, but have 8 tubes that you need to run, then you can stack 2 - 4 Tube holder's on top of one another allowing you to organize all 8 tubes.    
 
These are designed for standard 1/4" polyethylene tubing, but may fit other types of tubing with a similar OD.
 
*Includes:  5 RO Tubing Holders & 10 mounting screws.
