Prime-Line N 7015 2-Piece Adjustable Door Guide, 1-1/8 in L X 1-1/16 in W, Plastic, White

Was perfect for my recess door to replace cheap one fitted by our builder

Bought these for my 5th wheel camper's sliding bathroom door. The bottom of the door wobbled around too much. Easy to install and they keep the door stable now!

Great fit

Bought these because I mislaid the ones that came with the pocket door installation kit, as it was a couple of years between installing the door and finishing the casing. These are slightly bigger which means they fit deeper into the opening and will guide the door better when it is completely retracted into the wall.

When the builder installed our pocket door, he forgot to install guides, so the door banged around in the opening when being slid open or shut. I mounted these guides on the trim after the fact. Not ideal, but they're not very visible down at the bottom of the door, even when surface mounted. They're very adjustable, and the nice big nylon glides make for smoothing opening and closing. Installation took just a few minutes. Slick, inexpensive solution. By the way, I ordered both these Prime-Line guides and the identical looking Slide-Co guides, since they were cheap (a couple of bucks) and I thought I might end up breaking one when installing. The Prime-Line and Slide-Co guides are indistinguishable, but the Slide-Co guides came with four mismatched screws and the instructions on the package were for a different product, so personally I'd recommend the Prime-Line guides over the Slide-Co guides.
