Is it okay to hang a Polk Audio RTI A3 by the power port?

[Veedub]

Hi all

The power port has a slot for wall hanging.  Is this okay for the RTI A3, given it's size and weight?  Can I just use a normal wall plug or is there something better suited?

I need to shift speakers around, so these will go into my lounge for rear surrounds.  The current brackets in the lounge are not big enough for the A3.

TIA
