Thomas & Betts 153 – Frequently Asked Questions

1) What conduit size does the Thomas & Betts 153 locknut fit?
The Thomas & Betts 153 is a 6 inch locknut, so it threads onto 6 inch trade size conduit fittings and hubs. If your run is a smaller trade size, this is the wrong part - order the locknut matching that size instead.
2) Is the 6 inch Thomas & Betts locknut steel or die cast?
Steel. That is what gives it the thread strength to pull up tight on a 6 inch termination and stay put, and steel keeps the metallic path continuous through the enclosure wall for grounding.
3) Does a locknut like the T&B 153 actually bond the conduit to the enclosure, or do I still need a bonding bushing?
The 153 locknut makes a threaded steel-to-steel connection at the termination, which maintains mechanical security and electrical continuity through the box or panel wall. Where your installation calls for a separate bonding means at the fitting, the locknut alone is not a substitute for that - spec a bonding bushing in addition.
4) What part number do I give my distributor for the Thomas & Betts 6 inch locknut?
Ask for Thomas & Betts 153. That is the manufacturer part number for the 6 inch steel locknut, and it is the only model on the item.
5) Where is a 6 inch locknut typically used on a commercial job?
Large conduit terminations - panel and switchgear entries, industrial conduit runs, and equipment grounding points where the raceway lands on an enclosure. It is a termination-point part, used in pairs (inside and out) on a knockout or against a hub depending on the detail.
