Our MAI006 Cable Stacker comes in a resealable bag of 25 stackers. These are made to accommodate up to 6 non metallic sheath cables, or Romex. They can also accommodate RG6, RG59, Cat6, Cat5e, and other low voltage cables as well. Designed with the National Electric Code in mind, these stackers have a small lip to guarantee proper placement on the stud and insure the 1 1/4" from the face. They securely hold the cables in place requiring no additional steps or support. These are modeled after the 3M SI-1, only better since we have the knowledge of what works best, we have incorporated these lessons into the MAI006 Cable Stacker. We also made them a bright red so that they are visible and easy to identify. We also have many of the other parts electricians need at great prices electricians like! Please see our other items, and our newest item is the panel wire support pictured; available in our other listings, these supports are a great time saver when exiting a panel. Chack them out! Thank you for looking!
