Yes, Leviton offers patch-cords in inch lengths--these would be a make-to-order product.
To configure a standard cord as a length in inches change the last digit of the basic part number (first five digits) to "i". For example: 62460-7L is a 7 foot cord, 6246i-7L is a 7 inch cord.
We can do this with our 62460, 6D460, 5G460, 5D460, & 6AS10 series cords and all of our Atlas series cords. Cords can be requested in any inch length.
