I have closer mechanism out of window The spline in the T handle is stripped I checked across the tops of the spline on the closer and measures .315 It is identical to your 11/32" splined T handle.....which is .343. Is there a 5/16" spline T handle or Does the 11/32 provide the right clearances and fit for the male spline as I measured it?

Thanks for posting. I think it's possible that the 39-108 might be a better match. This has a spline size of 3/8". Carefully compare with your old Tee Handle to see if this might be closer.
