Wobble Wedges® are small (1″ × 1 ¼” × ¼”) tapered (4°) wedges made from hard clear (there’s also a black version for photographers) polypropylene or soft white vinyl, which is easily trimmed. They have interlocking ridge teeth to prevent slipping when stacked. The manufacturer lists a myriad of uses for these shims, including plumbers, installers, cabinet makers, homeowners, and even restaurants — for leveling those tippy tables.
They’re available in a variety of package sizes and from many stores (Lowe’s, for example, sells them in a eight-pack under the Plumb Pak label as “soft-ribbed shims”; other stores list them as “toilet shims”). A variety pack of 16 assorted wedges will cost you about $5. A six-pack is around $2, and, if you just need a couple, you can usually find a store with a display jar and get a wedge or two for less than $1 each.
Has anyone used these very much? What’s your opinion? I once trimmed one of the hard shims to wedge a battery holder and stop it from rattling around in some electronic equipment, but have no experience beyond that.
