Super lightweight Titanium Roller Wing Post weights 5-3/8 ounces and saves 2 ounces over standard post.
Measures 12" from where the wing sits on top of the rollers to the end of the post and 3/4" in diameter. Can easily be cut to a shorter length.
The problem with normal wing posts for internal slider wings, as well as steel roller bearing posts, is that they beat up or gall the aluminum internal runners.
Our design is the first to truly solve this problem. It uses nylon rollers (not steel bearings) to slide the wing. Steel bearings still have point contact which relieves no stress on the runner. The nylon roller provides cushion as well as a wider spread contact area for the runner, eliminating wear and galling.
