CIRCOPACK Aluminum Snap Hinge 1/2" 4 Pieces (Model 251) (1/2 Inch)

These hinges snap on round poles. Once you put them on you can take them off if you decide you want a different placement. The quality of the hinge is quite good. I think it's made of aluminum. The description about size is right on the button so measure closely. I was a little off the first time I measured and the company worked well with me in an exchange. The one I have now that are the second order fit exactly. Overall I think these are a great buy.

Good product but almost too tight. Struggled a bit getting it snapped on to the pvc post, but once it was in, it stayed put. Works as advertised.

I just received these... They do not have pre-drilled holes as shown. They are very rough - I will need to take a file to knock of the rough edges and round sharp corners as I will be touching them repeatedly. I tried to slip them onto 1/2 inch pvc and I will be required to force them on... so they are a LOT tight.. which might be ok since there aren't any pre-drilled holes... Not the quality I was expecting for $9 per hinge... I think I will be searching for piano hinge now and return these.

I bought these for a cat enclosure I am making out of pvc. They fit the pvc and they hold on tight.

It was all good

I received the hinges in the mail today, and it turns out they do not have a hole in the side for a screw to anchor them . . . so disappointed! Not sure that merely clipping them on the pipe will keep them in place!

Works great 👍
