When I order the shelving for our Beverage Air WTR60A worktop fridge I thought it would be one long shelf. But it came with two. I have the brackets and pins installed on the sides and front to hold up the shelves. The problem is that the only place for me to install another bracket in the back is where the fans and electrical equipment is. I would like to install something more permanent and better looking than a brick to hold the back part of the shelf up. Help please!
