Review on 53151 Pre Galvanized Square Extension Knockouts by Keith Orrillo
Versatile Knockouts Deliver as Promised!
After I put it to the test, I'm pleased to say these knockouts did not disappoint. They're a perfect addition to my electrical boxes, allowing for easy extension and modification of conduits. The pre-galvanized coating holds up well against harsh environments. The only drawback is that they may not be easy to install for those without experience in electrical work. Overall, I highly recommend these square extension knockouts for their durability and practicality.
- Easy to install with pre-galvanized finish that provides durability and resistance to corrosion.
- The square extension design may limit the range of fitting options for some electrical applications.
