3M 7000132935 Cable Stacker SI-1 2x4 Framing

Product Description

The 3M 7000132935 Cable Stacker SI-1 is a cable management device designed to center and separate multiple cables on a 2 x 4 framing member. It addresses NEC Article 300-4-(d) and Canadian Electrical Code Part I, Section 12-516 compliance by maintaining proper spacing between cable runs. Cables snap in for a positive lock, eliminating the need for additional fasteners that bundle conductors tightly together. The SI-1 body is made from reclaimed plastic. This device is installed by licensed electricians during rough-in wiring on wood-framed residential and light commercial construction.

The Cable Stacker SI-1 is suited for new construction and retrofit wiring applications where multiple cables must pass through or along 2 x 4 stud bays. It organizes parallel cable runs, aids in cable identification, and reduces the risk of heat buildup that can occur when conductors are compressed under a single staple or fastener. It supports compliance with both the National Electrical Code and the Canadian Electrical Code, making it applicable in US and Canadian jurisdictions.

Designed for use with standard 2 x 4 wood framing members in residential and light commercial wiring installations where multiple cable runs must meet NEC and Canadian Electrical Code spacing requirements.

Installation Notes

Installation is performed by a licensed electrician during rough-in framing stages before drywall. Power down any affected circuits before working in the area. Cables snap directly into the stacker body for a positive lock — no additional fasteners are required at the stacker location. Follow all applicable NEC and local code requirements for cable protection and spacing through framing members.
