ELECTRICAL BOX |
| 摘要 |
<p>An electrical box adapted to receive an electrical fitting. There are openings formed in the box to align with openings formed in the fitting. Separate threaded portions are positionable within the openings and can move apart upon insertion of a screw. But the threaded portion grips the screw when the screw is rotated. The speed of installation is greater than is possible with prior art boxes.</p> |
