Carlon S288 Snap-Loc Non-Metallic Base Spacer, 100-Pack

The Carlon S288 Snap-Loc Base Spacer is a non-metallic conduit support spacer engineered to deliver consistent separation and direct stress relief for duct mounting and conduit support systems. Each spacer measures 5.625" in width with a 3" thickness, and features a side dovetail rail-and-groove design that allows side-by-side interchangeable installation for flexible, reconfigurable layouts. Sold in a 100-pack, these spacers are manufactured in the United States and are built for professional electrical, industrial, and telecommunications infrastructure applications where reliable conduit spacing and stress relief are critical. The Carlon S288 is a practical solution for contractors and facility teams managing multi-conduit runs who need dependable, repeatable spacing without the corrosion concerns associated with metallic hardware. Whether supporting a single run or a complex bank of conduits, the S288's modular design lets crews add or remove spacers on the fly without special tools, streamlining installation and reducing labor time on large-scale duct management projects. Because the S288 is non-metallic, it also provides electrical isolation between conduit runs, an important consideration in installations where galvanic or grounding concerns come into play alongside mechanical support needs. This makes the S288 especially valuable on jobs where mixed-metal hardware could introduce corrosion risk or where code requires isolation between dissimilar conduit runs.

Carlon S288NHN – Frequently Asked Questions

1) Can I gang Carlon S288 spacers side by side to build a wider conduit bank?
Yes. The S288 uses a side dovetail rail-and-groove design, so spacers slide together side by side and interchange with one another. That lets you build out a bank as wide as the job needs and reconfigure it later rather than being locked into one fixed width. Each spacer is 5.625 in wide, so the width of a ganged row is that figure times the number of spacers you join.
2) What conduit sizes do Carlon S288 base spacers cover?
Seventeen size configurations, from 2x2 up to 8x3: 2x2, 2x3, 3x1-1/2, 3x2, 3x3, 4x1, 4x1-1/2, 4x2, 4x3, 5x1-1/2, 5x2, 5x3, 6x1-1/2, 6x2, 6x3, 8x1-1/2 and 8x2. You pick the one matching your conduit diameter and the separation you're building to, and each is its own part number (for example 4x2 is S288NJN, 6x3 is S288RLN).
3) I need a specific size of Carlon S288 spacer for a submittal. What part number do I put on the order?
Each size carries its own MPN off the S288 base. 2x2 is S288JJN, 2x3 is S288JLN, 3x1-1/2 is S288LHN, 3x2 is S288LJN, 3x3 is S288LLN, 4x1 is S288NFN, 4x1-1/2 is S288NHN, 4x2 is S288NJN, 4x3 is S288NLN, 5x1-1/2 is S288PHN, 5x2 is S288PJN, 5x3 is S288PLN, 6x1-1/2 is S288RHN, 6x2 is S288RJN, 6x3 is S288RLN, 8x1-1/2 is S288SHN, and 8x2 is S288SJN. Ordering by the bare S288 number alone won't pin a size, so give the full suffix.
4) Are Snap-Loc base spacers the same thing as the intermediate spacers that stack above them?
No. The S288 is the base spacer, the piece that sits at the bottom of a stack and carries the base flange and X-brace structure that sets the assembly on the trench floor or mounting surface. Stacked tiers above it use the interlocking side tabs and the snap clip to build up. If you're specifying a multi-tier duct bank, you need the base course plus the stacking pieces for the tiers above it, not base spacers all the way up.
5) What do Carlon S288 Snap-Loc base spacers actually do in a duct bank or conduit run?
They're the base layer of a conduit spacing system. The Snap-Loc duct spacers hold conduit at consistent separation, keep the run stable, and take direct stress off the duct so the pipe isn't carrying it. In a duct bank or an equipment room rack of conduit, they're what sets and holds your spacing while the run is placed. The base spacer is the piece that sits at the bottom of the stack, not an intermediate.
6) How thick is a Carlon S288 spacer, and how much run length does one 100-pack cover?
Each spacer is 3 in thick and 5.625 in wide. The pack quantity is 100 spacers, so what a pack covers along the run depends entirely on the spacing interval your spec or drawing calls for, not on the spacer itself. Work it as run length divided by your spacing interval, times the number of spacers per position across the bank width.
7) Are Carlon Snap-Loc spacers non-metallic, and does that matter in a wet or corrosive duct bank?
Non-metallic construction, which is the reason they're used in direct-burial duct banks, encased runs, and damp equipment rooms: there's no metal in the spacer to corrode against the concrete or soil, and no metallic path between conduits. For a contractor pulling PVC underground, that's the practical difference from a steel spacer.
8) Where are Carlon S288 spacers made?
United States. That's the detail that matters on federal, state, and institutional work where domestic-origin electrical material is written into the bid, so the S288 clears a domestic-sourcing line item on a submittal.
