87-021 in Aluminum frame- Need lubricant?

A handy person from USA says:
For this roller, which will get water falling in from outside the window, should I lubricate the roller after it is in the window frame?
Any suggestions for a lubricant to help this glide along the aluminum rail/window frame?

Thanks, Wannabe

Hello, Wannabe. Lubricating the 87-021 definitely wouldn't hurt. My recommendation would be to use silicone spray on the track or even a stick of wax like our 75-077.
