SWISCO - The Replacement Hardware Authority

Window crank mechanism

A quick learner from Illinois says:
My mechanism says BiltBest & has the number stamped on it 31538. Would EntryGard Dual Arm Operator Product Code: 39-031 be the correct replacement?

Thanks,

Jim

The 39-031 and 39-032 have both been associated with this number, but manufacturers change numbers and stamps all the time over the years. Going by a stamp alone is not the best method of identification. I recommend carefully looking over the pictures and dimensions we show for this hardware and comparing this information to your own hardware. That is the best way to confirm if the 39-031 and 39-032 will work.
