Mac Chain - Products: Waste Water Treatment Chain
All Mac mill chain with a 1" and a 1-1/8" rivet are constructed with Mac Precision Taper Fit rivets. (See above drawing). Mac P.T.F. rivets are superior in design compared with conventional rivets. When the P.T.F. rivet is pressed into the link, it provides 100 percent contact between the rivet and the sidebar, thus reducing wear and increasing chain life.
