Motor feeds, equipment drops and short flexible runs need a solid mechanical termination where the flex meets the box. The Nesco NES-155 is a 1-1/2 in zinc die-cast squeeze connector for steel flexible metal conduit (FMC), sized for a 1-1/2 in knockout. Electricians use this flex connector on industrial and commercial jobs where vibration or equipment movement rules out rigid conduit.
Why electricians pick it
- Squeeze-clamp design grips the flex with a screw-tightened strap.
- Connects steel flexible metal conduit to a box or enclosure.
- Zinc die-cast body at a lower cost than steel or malleable iron fittings.
- 1-1/2 in trade size for larger feeders and motor connections.

Pro tip from the counter
Punch the box with a 1-1/2 in trade-size knockout punch, which cuts a hole close to 2 in across, rather than a 1-1/2 in hole saw that leaves the thread too tight to pass. Then run the locknut down until its teeth bite through the paint, because on metal boxes that contact is part of the bonding path.
Best for: motor and pump connections, HVAC and equipment drops, industrial machine feeds, transformer and panel tie-ins
