Shim Washer Kit – Whiteside W300

Finally got the gap dialed in on my door panels—these washers let me tweak the fit by just a few thousandths at a time. The set covers a good range of thicknesses, and they don't slip or distort under the router's vibration.

I've been chasing a perfect fit on cabinet doors for weeks, and these washers finally got the reveal right on the first try. The thin shims are a lifesaver for that last tiny adjustment, and they're machined clean enough to seat flat without any wobble.

I was fighting a hinge gap on a cabinet door for an hour, and these shims sorted it in five minutes. They’re thin enough to make real micro-adjustments, and the kit covers every depth I’ve run into so far.
