A mounting assembly can comprise a channel member defining a channel and comprising a first side wall, a bottom wall a second sidewall opposite the first wall, an aperture between upper ends of the first and second sidewalls, and a ridge positioned on the bottom wall and extending along a longitudinal axis of the channel member. A first anchor member can comprise a first top wall, a first connector portion, and a first anchor leg extending downwardly from the top wall at a first anchor leg angle. A second anchor member can comprise a second top wall, a second connector portion configured to connect with the first connector portion, and a second anchor leg extending downwardly from the top wall at a second anchor leg angle. The first and second anchor members can be configured to be captured within the channel member when the first connector portion is connected to the second connector portion and the first anchor leg and the second anchor leg are positioned within the channel.
