Metallics SFLN150 – Frequently Asked Questions
1) What size conduit does the Metallics SFLN150 lock nut fit?
The SFLN150 is a 1-1/2 inch conduit lock nut, so it threads onto 1-1/2 inch trade size rigid or IMC conduit and 1-1/2 inch threaded fittings. It is the nut that pulls the conduit or connector tight against a box or enclosure wall. For other trade sizes you need the matching size in the series, not this one.
2) Do Metallics SFLN150 lock nuts meet Buy American or ARRA requirements for a government job?
No. The SFLN150 is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. If your project carries a domestic sourcing clause, this part will not satisfy it and you need a domestically produced lock nut instead.
3) Are Metallics SFLN150 lock nuts steel or zinc?
Both, in the sense that matters: the nut is steel with a zinc finish. Steel gives it the strength to be wrenched or screwdriver-tightened without deforming, and the zinc plating is the corrosion protection for normal indoor and dry-location work. For wet, corrosive, or washdown environments, spec a stainless or malleable iron alternative instead.
4) Is the Metallics SFLN150 a sealing or gasketed lock nut, or a plain one?
It is a plain steel conduit lock nut, zinc finished. There is no gasket or sealing washer in the part, so it does not by itself make a raintight or liquidtight joint. If the enclosure needs a rated seal at the knockout, use a sealing lock nut or a gasketed hub designed for that duty.
5) What are the shipping dimensions of a jar of Metallics SFLN150 conduit lock nuts?
The packaged jar measures 7.25 in height, 4.5 in length and 4.5 in width, at 2.49 lbs. Useful if you are stocking a service van shelf or a jobsite gang box and need to know the footprint before the order lands.
