SWISCO - The Replacement Hardware Authority

Truth Window Hardware

A home owner from Santa Barbara says:
Hi, I have several Marvin Windows requiring replacement of the operators. The original hardware is made by Truth Co, and the hardware P/N 39-035 and 39-036 on youy website looks very similar to my present hardware.

However I notice that one of the two lever arms has a different shape than the one I have. I have enclosed several pictures that show the arm in question. In your picture, it is the arm has an oval shape, whereas on my hardware the equivalent arm is narrow and has a jog in it.

I am ready to order several sets from you, but want to make sure that I am ordering the proper replacement hardware. If there is a better fit /different model number, please advise including picture with dimensions.

Thank you for clarifying this issue.

Thank you for posting. It's hard to make out, but it looks like you have an older version of our 39-035. The newer style we have should still work in your window.
