## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    It's not made of aluminum, as is in the listing, but rather PVC
  

*by A***R on Reviewed in the United States on April 6, 2022*

The Amazon posting indicates it's aluminum, but what I received was PVC. I checked on the RAB web site, and it confirms it's PVC with molded in color. It's well made, but will simply not be as strong as cast aluminum. PVC is OK, but remember that it doesn't have the strength of aluminum, and so the 1/2" molded thread will not be a strong. PVC also deteriorates over extended exposure to UV rays from the sun, so while it will be OK for 5 years or so, it will get even more fragile as it ages. It's interior diameter is 2 7/8", not 2 1/2 as other posters have posted, and so it will NOT fit with 3" male bases etc. Given it's PVC, you can use a interior cyl sander to remove material, if you're skilled with steady hand.

    It’s a cap. It works
  

*by B***E on Reviewed in the United States on June 8, 2022*

Needed to mount an outdoor pagoda light on a 3-1/2” pipe post.  1/2” thread Or post base lights available so this worked as a connectorSeems sturdyI’ll buy this again as the other lights need to be changed out.

### ⭐⭐⭐⭐ 







  
  
    Great product.  Can be difficult to remove years after installation.
  

*by J***D on Reviewed in the United States on March 11, 2018*

Sturdy.  Well made of PVC.  Holds up well. Snugly fits against PVC pipe.  Good price.  However, after about 5 years in a ground level installation, we wanted to switch our lamp from a 350w halogen to a 50w led lamp.  The cap would not let go of the underlying pipe.  While there is a small screw on the cap that locks it to the pipe, removing the cap from the pipe can be a chore.  We had to saw through the cap to get it to let go and purchase another cap.  I subtract one star  for a design that does not seem to account for disassembly.  Still, I bought another because I can not find a more suitable product out there.
