Beechcraft Travel Air, Baron, Duke, Bonanza & Debonair Towbar. Most Beechcraft models with 1/4" dia. tow pins on nose gear strut.
Collapsible Length: 20.5"
Overall Length: 37"
Seems solid. Only small complaint is the forks are tight to get around the pins on the nose gear. A spring loaded fork of some sort wouldve been easier, but still a good fit, just a bit tight.
This is a lightweight tow bar, but so far seems strong enough for the job of steering the aircraft for maneuvers in and out of the hanger. It does collapse into about half the working length and weighs so little taking it along in the aircraft is simple. I am not yet sure how well it will hold-up after frequent use.
