What’s the difference between a 3/8”-pitch chain,

and a low-profile 3/8”-pitch chain?

Standard 3/8”-pitch chains are full-size professional-type chains intended for

use on medium to large gasoline-powered saws, 3.0 to 6.0 cu. in. (50-100cc).

Low-profile 3/8” chains have the same pitch, but there are differences in the

drive sprockets and bar-nose sprockets used with low-profile chains. Standard
3/8” chains and low-profile 3/8” chains are NOT interchangeable. The phrase	DEFINITION	3/8”-PITCH CHAIN (72V)	LOW-PROFILE 3/8”-
“low profile” refers to the height, measured from the bar’s rail to the top of the
	OF PITCH	STANDARD PROFILE	PITCH CHAIN (91P)

cutter. On low-profile chains, the height is less than on standard chains. Low-

profile 3/8”-pitch chains are intended for use on electric saws, and small gasoline-powered saws up to 2.5 cubic inches (41cc).
