3M 7000132935 3M™ Cable Stacker SI-1, routes various number of cables in an organized way, 250/Case

The SI-1 stacker takes cable with an insulation outside diameter up to 0.145 in (3.7 mm). That covers typical small-gauge communication and low-voltage conductors. Anything with a thicker jacket than 0.145 in will not seat in the stacker channels.

Overall width is 1.19 in (30.2 mm), so it sits comfortably centered on a standard 1-1/2 in wide stud or joist face without overhanging. That width is what lets it center a bundle of cables on the framing member rather than letting them drift to one edge.

It meets RoHS 2011/65/EU, and 3M states compliance without exemption, so it clears specs that reject parts relying on a RoHS exemption. That is the compliance statement carried for this part.

A cable stacker is a plastic bracket that mounts on a stud or joist and holds several cables in separate, stacked channels so they stay centered on the framing member and stay identifiable by position. Staples pin one cable flat and can crush the jacket; J-hooks support a bundle in open air along a ceiling run. The SI-1 is for the point where cable crosses framing and you want multiple runs organized and separated rather than bundled together. Its channels accept jackets up to 0.145 in.

Order the SI-1 cable stacker as 3M MPN 7000132935. That number is the 250-per-case configuration, not a single piece.

Each case holds 250 stackers. For a rough-in where you are setting a stacker every few feet along a cable run, one case covers a sizeable job, and the pack size is fixed at 250 per case.

Construction is durable plastic, not metal, so it is non-conductive and will not abrade cable jackets at the support point. It is made in the United States, which matters on jobs carrying domestic-origin procurement requirements.
