Window crank split arm

Hello, thank you for posting,

Please start by reviewing the 39-253RB and 39-253LB operators that use the 39-529 track slider. These operators are compatible with the 39-451 and 39-452 or the 39-375 and 39-376 cover/handle depending on style preference. 

If you also need a bracket, please compare to the 39-513 and 39-514 style.

Let us know what you think and if you have any additional questions!
