๐ What it is
A 1/2-inch knockout squeeze connector is a metal conduit fitting used to secure electrical cable or flexible conduit into a knockout hole in an electrical box or panel.
๐งพ What the name means
- 1/2" KNOCKOUT โ fits a standard 1/2-inch electrical box knockout opening
- SQUEEZE CONNECTOR โ clamp-style fitting that tightens onto cable or conduit to hold it securely
โก What it does
This connector:
- Locks MC cable, AC cable, or flexible metal conduit (FMC) into an electrical box
- Provides a mechanical grip (strain relief) so the cable cannot be pulled out
- Helps maintain ground continuity in metal systems (when used with MC/AC)
- Often used in dry-location electrical installations
The โsqueezeโ design uses a tightening screw or compression mechanism that clamps the cable jacket or conduit firmly in place.
๐ Typical uses

- Armored cable connections
๐ง Simple explanation
This is a metal clamp fitting that goes into a 1/2-inch hole in an electrical box and holds conduit or armored cable tightly so it doesnโt pull out.
