Red Dot S130E-L – Frequently Asked Questions
1) What does the Red Dot S130E-L round extension adapter actually do on an existing box?
The S130E-L is an aluminum round extension adapter that mounts on an existing box or fitting to add depth and wiring volume. It adds 18.3 cubic inches of capacity, which is what matters when you are over box fill with conductors, devices and grounds. Diameter is 4-1/8 inches, so it suits round outlet boxes and covers of that size.
2) Do I need cable clamps or connectors with the Red Dot S130E-L, or does conduit thread straight in?
Conduit threads straight in. Cable entry on the S130E-L is by hubs, so you use threaded rigid or IMC conduit, or a threaded fitting, at the hub openings. There are no cable clamp provisions, so NM or MC cable would need an appropriate threaded connector at a hub.
3) Will the S130E-L round extension fit a 4-inch round weatherproof box?
The adapter is a 4-1/8 inch diameter round unit, which is the standard cast round outlet box pattern that 4-inch round covers and bodies share. It is meant to stack onto a round box of that bolt pattern; it will not adapt a 4-inch square or octagonal steel box.
4) Is the S130E-L extension adapter suitable for outdoor or wet location conduit work?
It is a cast aluminum extension built for threaded hub conduit systems, so it is the type used on exterior and damp-location boxes rather than indoor drywall rings. Cable entry is through hubs, meaning conduit threads directly into the adapter instead of entering through cable clamps or knockouts.
5) I am over box fill on an existing round box. Is adding an extension adapter a code-legal fix?
Adding an extension is the standard way to gain volume, and the S130E-L contributes 18.3 cubic inches that counts toward your box fill calculation along with the original box volume. That is usually enough to cover several added conductors and a device. Confirm the part number when ordering: the model is S130E-L.
6) Is the Red Dot S130E-L sold individually or in a carton?
The S130E-L extension adapter is sold each, so you can order the exact count the job needs rather than a full box.
7) What finish and material is the S130E-L, and will it corrode outside?
It is cast aluminum with a silver finish, the usual choice for exterior conduit boxes because aluminum does not rust like painted steel. Keep in mind aluminum is not the pick for high-chloride or strongly alkaline environments such as direct coastal spray or concrete contact.
