Casement slider info

A quick learner from New Jersey 07040 says:
I am looking to order truth Maxim left hand dual arm casement operator in white but also need to replace the window slider that's in the photos provided. The model# of the operator is stamped 31876 on the operator. There are no markings on the slider.

Hello, thank you for posting,

We should be able to assist, but to further review, are you able to show us the full operator? Is the style a single or dual arm? Thank you! 

A quick learner from New Jersey 07040 says:
Yes it's a dual arm. My biggest issue is the slider that's attached to one of the arms. I need a replacement for that as well. Thanks

Thank you for the additional picture,

Unfortunately the slider is not sold separately. The full operator will need to be replaced. Please review the 39-438B and 39-439B operators as a replacement option. Compare the dimensions to your original to confirm a good fit. I have also related compatible cover and handle kits on the page for your review.

Let us know if you have any additional questions!

Great I believe that's exactly what I need. Can you also provide the model number for the right hand bracket as well. I took a picture of the part. Thank you so much!

No problem! 

Please review the 39-545 and 39-546 brackets to see how they compare to your original. Let us know if you have any additional questions.
