We use a lot of these nylon cable clamps in installs. While they shouldn't be used for Category rated cable when used for computer networks, everything else is game. Keep an assortment of these and a box of 1/2" pan head Philips wood screws around and you can dress your cables with ease.
I like to mount the smallest cable clamp (no matter what the size of the wire bundle) then use a tie-wrap to attach the wire bundle to the clamp. This makes it very easy to add or subtract wires from the bundle later. (Cut the tie wrap and zip on a new one.)
