Mae sbrocedi sengl dwbl wedi'u cynllunio i redeg dwy gadwyn rholer math un llinyn, dyma lle daeth yr enw "singl dwbl". Yn nodweddiadol mae'r sbrocedi hyn yn arddull A ond mae llwyn tapr ac arddull QD ar gael wedi'u cynhyrchu fel cais cwsmeriaid. Mae ein sbrocedi sengl dwbl yn cael eu cynhyrchu â dannedd caled ac mae ganddynt orchudd lliw gwreiddiol neu ocsid du ar gyfer perfformiad uwch ac ychydig o wrthwynebiad cyrydiad. Mae meintiau stoc o sbrocedi sengl dwbl yn amrywio o ANSI #40 - #80/DIN06B-16B ond gellir cynhyrchu meintiau ychwanegol ar gais. Peth pwysig i'w nodi yw, er bod y sbrocedi hyn yn sbrocedi dwbl, ni fyddant yn gadwyn rholer llinyn dwbl.
