Replacement die cast metal T handle fits a common 5/16" spline and is held on with a screw in the end of the shaft.
Comes with screw. Measures 2-1/16" across.
This tee handle is appropriate for some 1964 Airstream and Yellowstone trailers that have Hehr 2400, Hehr 2600, and Hehr 2800 series windows (the model number will be etched on the outside of the backframe below the sill).
Replacement for plastic version that was Hehr part number 008-170. You may want a VTS-2530 handle extension if clearance is an issue.
