(For 1/2" 3/4" etc)

I see two types:
One type fits around the pipe and uses two screws fastened into the
wood (or whatever)

The other has a round copper piece where a large wood screw goes
through the middle and then two pieces with two copper screws hold the
pipe in place.

The first type seems much easier and cheaper but there must be a
reason or specific application for the second type. Anyone know where
to use the second type?

1) Where there's possible need to remove the pipe w/o removing the
clamp mount.
2) Whereever one wants...

Why would anyone "possibly need to remove a pipe" ? ...

Replace the water heater perhaps??? Many reasons and many piping
situations other than the plainest...

If the hanger were mounted permanently (say in masonry or concrete w/
Hilti), removing it isn't necessarily so simple, is it?
