Sliding doors wells and rails

Hello,

Our 23-041 roller resembles your part with the same convex wheel. See the dimensions below to confirm.

The 23-240, 23-241, and 23-242 are compatible bottom tracks but I'm afraid we don't sell the length you need. In cases like this, you can buy two smaller tracks such as one 23-240 and one 23-241, piece them together in the door opening, and cut the excess off with a hacksaw. Take a look and see what you think.
