Window crank

Hello,

Unfortunately, we do not carry a match for the old-style operator shown in your photos. We have one option that you may be worth considering but we can't make any guarantees and modifications may be necessary. See the 39-344, which has a similar base to the assembly you're looking for. You'll notice that ours does not use the same fitting at the end of the arm, so the tracks would also need to be replaced. See the 39-504 or 39-520 depending on how the original track attaches to the bottom of the sash.

As we mentioned, we can be sure if this will work and adaptations such as retrofitting or replacing the sill trim may be required. Review the specifications of each part and see what you think. Thanks for posting.
