Which is irritating, because you have to tamp the ground very tight to keep the riser from pulling off the box when you remove the lid. Especially when some landscaper adds 6" of mulch to a bed, so you have to add a riser,and the mulch won't hold the riser on.
Are you saying that you run into stubbies that need a stubby put on top to clear the mulch? I think if this were the case I'd remove the original stubby and just install a standard. T&M...
