So, after some looking around, I’ve decided that the look that the galvanized punched flat-bar was not replaceable. All other cheaper options did not give the desired look and feel. So, I shelled over the $160 or so and purchased it from Home depot: Flat-Bar-Home-Depot
But I ran out of 6-inch long magnets …
I purchased 9 of the 48″ long bars … the store only had 10 in stock. I cut 3 of them in half to give me a longer (almost the width of the couch) look.
I even leveled it like a pro! with my good old laser level tool purchased at Canadian tire: The “Mastercraft Hawkeye Laser” (turns out the one I have has been discontinued, probably for the best as its not very good).
All in all, super impressed with the results. Thanks, Jenn, for the Idea.
