Casement Window Track

To whom it may concern, good morning...

Attached photo's is a track from a kitchen casement window which swings outward. From looking from the inside of the kitchen this is the left side panel. The black piece (clip) seems to be worn down and is sliding off the track on the actually panel.

All together we are actually looking to replace the whole arm and clip, pretty much what the photos sure. As mentioned from the previous line this is the left side looking from inside but we are also looking to replace the right side this way both sides are new/updated.

Any support identifying the part numbers would be great. 

Tom -

So if I'm following you correctly, this model is replacing the entire assembly then? I wont have to order anything else, the will replace what was attached to the actual glass panel to the casement of the window?

Also reading the description of the item this comes with two so I only have to order 1 (one) of the 36-048 to replace both left & right?

Thanks,
Tiago
