Like most products of this type it is not investment cast for chamfering/reaming/etc. for filling holes of different sizes. So drilled for a 2" hole in wood, pretty typical brand name wood, but they're undersized. Two or so turns of electrical tape solved that problem without having to resort to glue or silicone. Plus they work pretty well. Insert comes complete out and you can customize the look of the smaller hole too.I deducted 1 star for the firmament issue but otherwise it's a much better deal than the 1 for the same price at Lowe's that I bought previously.
