SWISCO - The Replacement Hardware Authority

What brand/model is my window

A home owner from Winchester MA says:
I have casement windows that need the crank hardware replaced.

The window crank handle has the ID P4601 it also has the letters MI written inside a hexagon

The house is in the Boston area and I think that the windows are from the mid 1990s

Can you tell me what brand of window that I have? Do you have parts for this brand/model of window.

I am a home owner but I am pretty handy.

I would appreciate any help you can give me, and I will buy my parts from you if you can supply them.

Thank you very much

Hey, Finbar, thanks for posting. This looks a lot like the older version of our 39-091 and 39-092. Carefully compare them to your own hardware and see if you could use them as replacement operators.
A purchasing agent from Northridge California says:
Above item is exactly what our customer is in need of, the operator measures 5-1/4" wide and 1-1/2" front-to-back not including the screw-in area. did the replacement 30-091 and 39-092 work?

she needs one left and one right hand,

thnak you
