I have three exterior doors that had the adjustable sill caps & was missing some of these plugs & after contacting Home Depot & Lowes to see if they had any of these plugs & was told they didn’t I was able to locate your site & ordered a package of four to replace the missing & bad plugs so I was very well pleased that Better Door had these plugs available, in the future if I have any future ones that go bad I will certainly purchase some more .

Just what I’ve been looking for and couldn’t find anywhere else. Fast service and perfect fit. A small cost for something that has been aggravating me for a long time (the missing plug).
