Carlon Part # E977HC-CTN - Carlon 1-1/2 In. Pvc Conduit Clamps (5-Pack) - Plumbing Clamps - Home Depot Pro (wilmar.com)

Which require that you thread the wires through each loop, which is tedious.

Better to use these

1 1/4 Inch Nail-In Drive Rings - 25 Pack | ShowMeCables.com

which allow you to place and remove wires quickly. The Conduit clamps are made to hold conduit. The wire rings are made for what you want to do. They hammer in, and don't require screws. The loop can be turned 90 degress during wire placement, then swung back into the correct orientation after the wire(s) have been placed along the route.

You're welcome. The wire rings don't need to be hammered all the way in, (just a half-inch or so will suffice in a wooden table structure) unless you're running telephone wire along the rear walls of tenements in Harlem, during the 1970's, under the watchful eye of the evil foreman.  That method required a star drill, (no cordless drill motors back then), a lump hammer, lead anchors, a three-section ladder, and a fellow worker acting as a watchman to let you know when a window would open suddenly and trash would be dropped on your head. But that's another story...

Thanks for pointing out another product.  IMO, they're useful if no track or scenery have been added; otherwise, the pounding required to drive the nail could be problematic.

An alternative method for using the conduit clamps is to use only one screw, and don't completely snug it up.  By doing this, the conduit clamp has enough flexibility to create clearance for adding wires, while maintaining enough strength for the clamps to hold the wires in place.  Also, I'd much rather bump into or scrape against a plastic conduit clamp while working under the layout.

I use these:

They come in a variety of sizes to fit your needs, and there's no pounding to rattle your table.  You can turn them in any direction easily as needed.  The smaller ones can be twisted in by hand in softer parts of the wood (not in knots).  Wires can be added and/or removed easily also.  (Some brands don't have the little washer-like stopper near the threads.)
