Description of Leviton 23452 H Horizontal Fluorescent Lampholder
Snap-In. Lamp support clip. Horizontal mount. 2G11 Base Twin Tube Fluorescent Lampholder. Every electrical component is subject to Leviton’s strict in-house quality control and must meet or exceed applicable industry standards.
I had to enlarge the mounting holes of the clip with a drill. This was an easy fix for me. It would be better if the mounting hole size was specified in the product specifications. The rest worked fine.
