Plaster thickness

[Heliman500]

Getting ready to set my 1.5” pipe flange fitting to accommodate microbrite lights. I am wondering how thick the plaster (quartscapes) should be so I can determine how far the flange should protrude. The fitting shown in picture is not glued so pipe can be recut if need be. Thanks in advance

Plaster is usually 1/2" thick (3/8"-5/8"). You can shorten that pipe a little if you like but it looks OK.

@sktn77a awesome thank you. With the flanged collars I have will the plasterers be able to get plenty of plaster behind the flange?

Sure, that's what they do all the time.
