Flush Mount Volume Knob to Vinyl Siding
 

I'm in the process of installing some outdoor speakers for the deck. Additionally, I'm going to install an outdoor volume knob for the speakers.

What I would like to do is mount the knob similar to the way my outdoor receptacle is mounted (See Enclosed Photo).

I'm looking for the white box that's surrounding the receptacle. My plan is to use a similar box and put the knob in the middle of it.

My question is, what is the white box in the picture and where can I get one? Is this some component of vinyl siding? I've looked in the big box stores but no luck.

Thanks for any clues.

Try this link there should be something similar but designed better. www.midamericacomponents.com/ Good luck BOB

Thanks Bob, I'll check it out.

Anytime!

looks like j channel
 

that photo looks to be of J channel cut in four pieces then putty? plaster? in the middle is all. though there are premade like Bob said that work better and will not leak behind as that J channel could. good luck!
