1970s Boler Torque Bar Window Operator

Window operators for 1972 to 1974 Bolers and mid- to late-70s Triple E Surfside fiberglass trailers. Also used on some canned ham trailers like Prowler, Ventura, Taurus and others.

There were dozens of sizes and configurations of torque bar operators used through the years on vintage trailers. It’s really hard to find the correct operator for each type trailer. Here’s one we are sure is right. If you have others you know of, let us know.

2-3/16″ tall x 1-3/16″ wide x 1/2″ thick. Mounting holes are about 1-3/4″ apart. Operator knurl extends 3/4″ from side of operator.

Hub accepts a 1/2″ diameter torque bar. When choosing the correct version, please take note on your trailer of how far the hub (socket) that accepts the torque bar projects from the operator.

The version shown in the photo has the deepest 11/16″ hub projection.
