Roto Replacement Parts

A quick learner from Las Vegas (parts are for Roatan, Honduras) says:
I have 8x right open casement windows and 9 left open casement windows. The roto parts are corroded due to the salt water environment and I am looking to replace the associated parts. Any help would be greatly appreciated.

Hello,

Thanks for posting! We do not carry an exact replacement match for your operator however, our 39-315 may be worth considering as replacement. The opposite handed version is part 39-316. To determine if these will be a fit for your hardware look over the dimensions from the diagram below.

These operators are compatible with the 39-114L crank handle and you may also need the 39-105 Stainless Steel Detach Clip as well as the 39-513 and 39-514 stud brackets.
