INSTR COVER 3-1/8" BLACK ALUM
Item as described. Perfect fit
Nice looking black aluminum block plate. No hardware included
I originally purchased the plastic version of this product, which was okay, but I wanted something a little nicer and more resilient for our installation. The aluminum plate did not disappoint! It is high quality and is, in my opinion, a much better product.
Prompt,, exact
This is a 2 1/4 aluminum plug WITH the 4 corner holes pre-drilled. If you are looking to plug an instrument hole, this is the one you want.
As described and of good quality
Quality hole plug at a good price.
