• WARNING:  All Motorized Drive Roller (MDR) Poly-O endcaps do not have uniform groove separation. Itoh Denki's groove separation is 3/8". DuraBelt's groove separation is 1/2", so it only works with Interroll, PulseRoller and Pancake MDRs. You can use Dura-Belt's Poly-O with Itoh Denki's MDR, but you must connect the MDR to the first slave roller on each side of the MDR with narrow flat belts.
