I have just had maple hardwood stairs put in, and would like to install a carpet runner (we have two kids and a dog, so stair safety is a concern). I looked around for brass rod/bracket combinations and found one type, but it requires that I drill holes in the maple treads. I don't want to do this and ruin the look of the stairs. I am looking for rods that will attach to the risers only. Do you have any idea where I might be able to locate these?
