Are the metal connectors stronger than the nylon connectors?
Simple answer yes, complicated answer no. It really depends on the treatment of the marquee. Although both connectors are equally strong, if it is dropped often, dragged or in constant sun it would be wiser to choose metal connectors. However, only nylon connectors are available on the 30 series marquees; metal connectors are standard on the 35 and 40 series marquees.
