Sliding two - door closet hardware

Hello,

Thanks for reaching out! Your closet door roller looks a lot like our 23-042 Mirrored Closet Door Roller with a round top. To confirm that this is the right replacement, carefully review and compare the dimensions below.

We do not carry an exact replacement for your track but our concave style tracks should work well as a suitable replacement. For the 63-3/4" track, you'll be able to use the 71" 23-272. In regard to the 77" length, I suggest purchasing two of the 47" tracks, 23-270. 

You'll be able to cut each of these tracks to size to install them in the spaces.
