Back plastic mount for kitchen drawer slides
Start by viewing our 32-018. Look over the dimensions, particularly of the size of the gap that accepts the track, and let me know if you think this could work for you.
The 32-089 certainly could be correct based on that size, though note it also has a small groove in the right-hand socket to accommodate a flange found in certain right-hand drawer tracks. The 32-089 is also designed for tracks that do not slope in the rear (i.e. the tracks are level). The 32-018 as well as the very similar 32-119 have more of a slope.
That said I do want you to consider the 32-119 as well. Its dimensions are very similar to the 32-018 (1" x 3/8" vs 31/32" x 7/16", respectively), so if the specifications of the 32-089 I just explained don't seem right, I think the 32-119 might be what you need.
Will it accommodate my 1" track?
