Arlington Industries RTSL409 – Frequently Asked Questions

1) What do I order to get a complete Arlington Roof Topper support, and what is the sled for?
Three pieces are sold under the Roof Topper line and they are not the same thing. RTSE405 is the 5 inch wide base with no sled. RTSE409L is the 9 inch wide base supplied with the sled. RTSL409 is the 4 x 9 inch sled on its own, for adding to or replacing the cover on an open base. If you are buying the 5 inch base and want a sled over it, the sled is a separate line item. The 9 inch version already includes it.
2) Will the Arlington Roof Topper raise my rooftop conduit enough to satisfy the inspector on NEC rooftop clearance?
That is what the Roof Topper is built to do. Arlington states its purpose as raising conduit off the roof surface to comply with 2011 NEC requirements, so the run sits clear of the membrane rather than lying on it. The base is a free-standing support, so nothing gets fastened through the roof and the membrane stays intact. What the inspector will still want is the spacing of your supports along the run and the clearance your particular code cycle calls for, and that comes off your drawings, not off the support.
3) Should I use the 5 inch base or the 9 inch base for my conduit run?
Width is the deciding factor. The 5 inch base handles a single run or a narrow pair of conduits. The 9 inch base gives you room to carry several raceways side by side on one support, which is what you want for a multi-run feed to rooftop units rather than setting two rows of small bases. The 9 inch also arrives with its sled, so a bank of conduit gets covered in one order.
4) How much weight can an Arlington Roof Topper base hold?
1,000 lbs load rating on the Roof Topper base. For a rooftop electrical run that is not the governing number in practice, conduit and cable weigh a fraction of it, but it does mean the support takes foot traffic from a tech walking the run and the weight of a heavy multi-raceway bank without deforming. Space your supports to your conduit's own span requirement, not to the load limit of the base.
5) Will a plastic conduit support survive years of sun and weather on a roof?
The Roof Topper is molded from 100 percent UV recycled plastic, so it is stabilized against the exposure that cracks and chalks ordinary plastic on a roof deck. It is also non-metallic, which means no rust streaking down the membrane and no galvanic issue where it contacts your conduit. For a property manager standardizing across a portfolio, it is the same part on every roof with no coating to maintain.
6) Is the Arlington Roof Topper made in the USA for a project with domestic sourcing requirements?
Made in the United States. That matters on public work, municipal and government buildings, and any job carrying a domestic-content clause, where a rooftop support is the kind of small commodity item that gets overlooked in the submittal and then flagged.
7) Can I buy just the sled cover to add to Roof Topper bases I already have on the roof?
Yes. RTSL409 is the 4 x 9 inch sled sold on its own. It fits the open base style, which is what Arlington means by the SLED for Open Base only designation, so it is the right part for retrofitting cover onto bases already set or replacing a sled that got damaged during other rooftop work. If you are buying new and want the sled included, the 9 inch RTSE409L comes with it.
8) How many Arlington Roof Topper supports come in a box?
Roof Topper bases ship 10 pieces to a package. Worth knowing before you price a job, because a long rooftop run at typical support spacing eats a box fast, and ordering by the piece when the carton is 10 is how a crew ends up short on the second day.
