Purpose & Audience

The CALBRITE S61000LN00 is a 316 stainless steel locknut designed for 1 in trade size RMC and IMC conduit. It provides a secure threaded connection for electrical installations requiring corrosion-resistant hardware in demanding environments.

Questions about this item

Will the 1 in locknut thread onto my existing 1 in RMC or IMC conduit without re-threading?

Yes — the locknut is made for 1 in trade-size threaded RMC and IMC, with a 1.21 in inside diameter that matches standard conduit threads.

How can I confirm the S61000LN00 is seated correctly after installation?

The polished 316 stainless steel finish should sit flush against the fitting with no visible gap, and the UL514B marking (file E308159) will be visible on the nut face.

Does the box contain only the locknut or are gaskets and conduit included?

Only the single locknut is supplied; gaskets, conduit lengths and other fittings must be purchased separately.
