Metallics RJK1 – Frequently Asked Questions

1) What conduit sizes will the Metallics RJK1 roof jack kit handle?
The RJK1 roof jack covers pipe and conduit from 1/4 inch up to 2 inch, which spans the common EMT and rigid conduit sizes run up through a roof deck. Base is 4-1/2 inches, so that is the footprint sitting on the roof surface around the penetration.
2) Do I need to buy fasteners separately to mount this roof jack?
Plan on supplying the screws. The Metallics roof jack base attaches with self-piercing framing screws through the mounting points, and those are the fastener type the kit is built around. Everything else needed to make up the penetration comes in the kit, bagged together.
3) Is a roof jack enough to weatherproof a conduit penetration, or do I still need to flash and seal it?
The jack gives you the base and the sized opening; you still seal it. The install sequence calls for weatherproofing material applied around the base perimeter once the base is fastened and the conduit is through. Position the base with roof slope and drainage in mind before you fasten it, so water sheds off rather than pooling at the upslope edge.
4) Can I use an electrical roof jack for refrigerant lines or low voltage cable, or is it conduit only?
Anything that falls in the 1/4 to 2 inch range works mechanically. Listed applications include HVAC refrigerant line and control wiring penetrations, antenna feeds and communication cable runs, fire alarm and security wiring, and solar PV conduit. The jack does not care what is inside the pipe, only the outside diameter it has to seal against.
5) Is the Metallics roof jack sold as one complete assembly or do I order pieces?
One part number, RJK1, covers the whole kit, bagged. The components that make up the penetration ship together rather than being ordered as separate line items, which is what a property manager or maintenance crew wants when stocking a few on the shelf for retrofit work.
6) Is the Metallics RJK1 roof jack made in the USA for spec and procurement requirements?
Country of origin on the RJK1 is the United States. That is the detail institutional and government buyers usually need on the submittal when domestic sourcing is written into the job.
