Difference between 39-090 and 39-187?

A quick learner from Palm Springs says:
Hi there!

My window guy had me order the DYAD 5" CRANK numbers 39-090 and 39-089 (for the left and right windows that we need to replace) from y'all and I currently have them. They look exactly the same as the 39-187, but want to double check before I spray paint them, (as I need them in an aluminum color to match). Do you think it's safe, or should I return the 39-090 and 39-089 for the 39-187?

Thank You!

Hey, Lyn, thanks for posting. I can't really tell which of these two types of operators you have based on your pictures. They key difference, you see, is in the arms.

It's a real subtle difference, and honestly it's even hard for me to pick it out sometimes. That said, take a look at the 39-187 and 39-090. Look at the arms as they come out of the base. You can kind of tell that the 39-187 has a sharper bend to it, almost a rough "E" shape, as opposed to the 39-090's more gentle "S" shape. Which do your arms have?

here's the inner workings of the crank (not the same one we need replaced as it is in a rental property of ours atm, but a pix of one that's identical, except for the color). i am hopeless, still can't tell which is closer to the right shape, 39-187 or 39-090. or would either work? i have the 39-090 and would love it i could make that work - lol!!
also, will need to paint it... would just regular spray paint work, do you think?

Ah, I see. Unfortunately, it looks like your operator arm more closely matches our 39-187 & 39-188. The arm offset has a vague "E" shape, rather than an "S" shape.

Thank you for the info!! Any chance this comes in silver? If not... Is painting an option?? Also, is over night shipping an option?

Unfortunately, these operators are only available in white, beige, or bronze. However, you can try using Krylon aluminum spray paint and their clear coat paint.
