Ya, pfr means calculate by 1 ft run.
For example, if the cabinet 5 ft length and it cost rm100 pfr, ----> rm100 x 5 = rm500

In the other hand, if calculate in psf, it means 1ft x 1ft = 1 fts.
For example, if the cabinet 5 ft length and 2 ft width and it cost rm40 psf, --------->rm 40 x (5x2) = rm400

Have a nice day~
