PFT installation expert Jared talks about one of his favorite accessories on a vinyl siding job, vinyl siding mounting blocks. He has even used them on his own home.
Vinyl mounting blocks can be used to mount a variety of things, from lights and receptacles to water spigots. Adjustable mounting blocks are able to be used with various thicknesses of products, which works well when installing vinyl siding with contoured Fullback siding insulation.
Simply nail the base to the wall. Install the siding and insulation around the base, butting the insulation all the way against the block. To finish, you snap the adjustable channel ring into place for a nice, clean fit.
