truth casement operator 30470 LH

Thanks for contacting SWISCO. Without pictures I'm afraid it's difficult to say with certainty what you need. However, that number has been associated with our 39-031 and 39-032 EntryGard Dual Arm Operators in the past. Take a look at them and carefully compare with your old parts to see if they match.

The only difference between the two operators is whether they or left or right-handed. In your case, you have the 39-031.
