Mae sbrocedi cadwyn cludo dwbl-draw yn aml yn ddelfrydol ar gyfer arbed lle ac mae ganddynt oes gwisgo hirach na sbrocedi safonol. Yn addas ar gyfer cadwyn dwbl-draw, mae gan sbrocedi dwbl-draw fwy o ddannedd na sbroced safonol o'r un diamedr cylch traw ac maent yn dosbarthu traul yn gyfartal ar draws y dannedd. Os yw eich cadwyn gludo yn gydnaws, mae sbrocedi dwbl-draw yn bendant yn werth eu hystyried.
Mae sbrocedi ar gyfer cadwyni rholer dwbl ar gael mewn dyluniad sengl neu ddannedd dwbl. Mae gan sbrocedi un dannedd ar gyfer cadwyni rholer dwbl yr un ymddygiad â sbrocedi safonol ar gyfer cadwyni rholer yn ôl DIN 8187 (ISO 606). Oherwydd traw cadwyn mwy cadwyni rholer dwbl, mae'n bosibl cynyddu gwydnwch trwy addasiadau dannedd.
