Check out our 23-242. This is the closest match we have to your track. Could you use this as a replacement?
I have the need for the same Stanley Home Decor sliding doors floor track, as posted and pictured on June 21, 2014, by Quick Learner from Arlingrton. The Stanley part is #4144. It needs to be 92" long.
The only possible problem that I see in using your #23-242, is that the outer lip may not meet our carpet. As you can see in his picture, one outer lip is flat and extends further than the other outer lip.
I am familiar with the old track, and how it had a little extra width to it so that it could meet the carpet. Unfortunately this older version is no longer made. The 23-242 is the only part we carry at this time that will work for you.
I am sorry for the inconvenience. We just don't have anything wider.
