Raceway-Mounted vs Remote-Mounted Channel Letters: A Buyer's Mounting Guide

Once the letter style is chosen, the next practical question is how the power supplies and wiring are mounted. For channel letters this usually comes down to two approaches: a raceway mounted on the wall, or a remote power supply mounted away from the letters. The difference affects install time, how the wall looks, and how the sign is serviced.

What a raceway is

A raceway is a rectangular enclosure — typically aluminium — that houses the power supplies and collects the wiring for all the letters in one place. The letters mount onto or near the raceway, and the electrical termination happens inside the box. Instead of running many individual wires and transformers across the wall, you have one enclosure that consolidates them.

The practical upside is fewer wall penetrations and a faster, simpler install: the electrician connects power to the raceway, not to a dozen separate points. The trade-off is that the box is visible on the wall. It can be painted to match the surface, but on a clean glass or stone facade it is still a box.

What remote mounting is

Remote (or remote-power) mounting puts the power supplies in a separate location — an electrical room, above a dropped ceiling, or behind the facade — and runs the wiring to the letters through conduit or inside the wall. From the front, there is no box: the letters appear to float with only their mounts showing.

The upside is a cleaner facade. The trade-off is more wiring labour and more wall penetrations, because each letter or group still needs a path back to the remote supply. Service also means accessing the remote location rather than one visible box.

Install cost and time

Raceway mounting is generally the faster and lower-labour option, which matters on retrofits, masonry walls, and tight schedules. Remote mounting costs more in wiring and planning but is often specified on new construction where conduit can be built into the wall, or on design-sensitive facades where no box is acceptable.

Wall impact and service

A raceway centralises the power supplies, so a future swap or inspection happens in one place. Remote mounting spreads the supplies out, which can be neater visually but slower to service. On fragile or uneven surfaces (glass, tile, old masonry), a raceway also spreads the load across a larger footprint instead of many small penetrations.

Specifying mounting with PEXEO

Tell your supplier the intended mounting method when you request the quote; it influences how the letter backs and standoffs are fabricated. Letter height is customizable from 1 cm to 300 cm, the minimum order quantity is 1, and production typically runs about 10–12 days after the specification is confirmed.

As with every PEXEO sign, artwork can be supplied in any format or designed from your brief, and the indoor/outdoor ingress-protection rating must be confirmed before production — this applies to the letters and to how the wiring is protected. The contact page is where the mounting brief gets reviewed.

Mounting decision checklist

Choose raceway when speed, cost, or wall condition favours one consolidated box. Choose remote when the facade must stay clean and the building plan allows concealed conduit. Either way, state the wall type and the mounting method in the brief so the fabrication matches the site.
