Connection sleeve 50/60

It is recommended to always use duplex multidirectional rollers even though they are sold as simplex rollers. It is easy to make one duplex roller out of two simplex rollers with the MTR 50/60 connection piece. Two simplex rollers and one connection piece make one duplex roller. The same connection piece is compatible with the MTR 50 and MTR 60 mm multidirectional rollers.
