3M ScotchCode SWD-R Write-On Wire Marker Refill Roll, 0.75 in x 1.375 in
The 3M ScotchCode SWD-R Write-On Wire Marker Refill Roll is a blank, write-on tape refill built for compatible ScotchCode wire marking dispensers. Each individual tab measures 0.75 in x 1.375 in, giving electricians, panel builders, and maintenance technicians a generous surface for hand-writing custom wire, cable, conductor, or terminal identification directly at the job site or in the shop. Because the SWD-R ships as a refill roll, crews can quickly restock an existing ScotchCode dispenser without replacing the entire marking system, keeping labeling workflows moving on active jobs. This write-on format is especially useful when circuit numbers, panel designations, or custom notes need to be added in the field rather than relying on pre-printed characters.
Key Features
- Tab Dimensions: Each write-on tab measures 0.75 in x 1.375 in, sized for clear, legible wire, cable, and terminal identification.
- Write-On Tape Format: The blank tape surface accepts permanent marker or an approved writing instrument, allowing fully custom, on-site labeling instead of relying on pre-printed characters.
- Refill Roll Convenience: Designed as a direct replacement roll for compatible ScotchCode wire marking dispensers, so restocking is fast and does not require a new applicator.
- ScotchCode System Compatibility: Works within the broader 3M ScotchCode wire marking platform, supporting consistent, standardized labeling practices across an entire facility or project.
- Model SWD-R: Clearly identified by the SWD-R model designation for straightforward reordering and inventory matching when it is time to restock.

3M SWD-R – Frequently Asked Questions
1) What size are the tabs on the 3M ScotchCode SWD-R write-on wire marker refill roll?
Each write-on tab on the SWD-R roll measures 0.75 in x 1.375 in. That gives room to hand-write a circuit number, panel designation, or terminal ID and still keep it legible once the tab is wrapped on the conductor.
2) Is the SWD-R blank, or does it come with pre-printed numbers?
Blank. The SWD-R is write-on tape, so the surface takes a permanent marker or other approved writing instrument and you create the marking yourself. If your wire counts and circuit assignments get decided on site rather than off a drawing, that's the point of this format over pre-printed character rolls.
3) Can I use the SWD-R refill in my existing ScotchCode dispenser, or do I need a new applicator?
It's a refill roll for compatible 3M ScotchCode wire marking dispensers, so you reload the dispenser you already have rather than buying a new applicator. Keeping to the genuine 3M roll is what keeps the tab sizing and roll format matched to the dispenser.
4) Can I substitute a Rack-A-Tiers wire marker for the 3M SWD-R refill in my existing ScotchCode dispenser?
No. The SWD-R is sized and formatted as a direct replacement roll for compatible ScotchCode dispensers, which is what makes restocking seamless without replacing the applicator. The Rack-A-Tiers 52480RD Mark My Wire system and the 52493 U-Phase valve wire marker are standalone marking products from a different platform and are not ScotchCode dispenser refills. To keep an installed ScotchCode dispenser in service, order the SWD-R roll.
5) What is the difference between the 3M ScotchCode SWD-R refill roll and the Rack-A-Tiers 52480RD Mark My Wire system?
The SWD-R is a blank write-on tape refill roll with 0.75 in x 1.375 in tabs that restocks a compatible ScotchCode dispenser, so you keep the applicator you already own and only replace the tape. The Rack-A-Tiers 52480RD is a Mark My Wire wire marker system supplied in red, a self-contained marking product rather than a refill for the ScotchCode dispenser. If your crews are standardized on ScotchCode dispensers, the SWD-R is the one that drops into the existing hardware; the 52480RD is a separate system you would adopt on its own terms.
6) What part number do I reorder to restock write-on wire markers?
Order model SWD-R, the 3M ScotchCode write-on refill roll with 0.75 in x 1.375 in tabs. One model designation covers it, so there is no size, color, or character option to specify.
7) Should I use write-on wire markers or a pre-printed number system for a panel job?
Pre-printed character books win when you are marking sequential conductors to a known schedule, since you just pull the digits. The SWD-R write-on roll is the better call when circuit numbers, panel designations, or custom notes are determined in the field, or when the label text isn't a number at all. Many panel shops carry both and reach for the write-on roll for as-built corrections and odd terminal points.
8) I need to mark phase on valve and control wires in the field - is the ScotchCode SWD-R the right choice or should I use something else?
Both work, but they are built for different marking tasks. The SWD-R gives you a blank write-on surface, so circuit numbers, panel designations, or custom notes decided on site can be hand-written directly on the tab. For straight phase identification, the Rack-A-Tiers 52493 is a 5-inch U-Phase valve wire marker built specifically for that job. Buyers who need custom text choose the write-on SWD-R; buyers who only need phase marking on valve wire often prefer the dedicated U-Phase marker.
9) Will a refill roll of write-on markers work for standardizing wire labeling across a whole facility?
Yes, and that's a common use. The SWD-R sits inside the broader 3M ScotchCode wire marking platform, so a facility that standardizes on ScotchCode dispensers can keep one refill part number in the stockroom for every maintenance crew. Typical applications include control cabinets, terminal blocks, wiring harnesses, and MRO labeling programs.
