Fantastic upgrade to my M35 Bonanza. No more instructing passengers how to unlock the door steward. Works great and exactly as advertised. Install took about two hours after gathering the right tools. Everything needed was in the install kit and super easy to complete the work.

Nice product, works well. You must close the door with your hand closer to the bottom latch when closing from outside. It will hold the door full open, even against prop wash. Great for summer.

Great product. From the complete kit with more than you need for your install to a perfect explained and pictured instructions. Often times you have to read the engineers mind to decipher the IKEA like instructions provided with a product. Not on this one! Our customers loved it.

Works great on my 1972 Piper Cherokee 180. Easy to install (though I messed up on some riveting and needed an education on how to remove a CherryMax rivet - those things are NOT falling out!). Not counting my installation mistake, it took about 2 hours to install working slowly. It holds up to prop wash taxi’ing on a hot day and is no problem to close.

I purchased the door steward after a taxing plane ripped the factory catch off the door. We just installed it, and im already in love. The door is so smooth, and taxing planes shouldnt be a problem any longer!

5 stars so far. Tired of dealing with the aging support rod on my Beechcraft and worried about gust of wind damage with original one on the plane.

This door steward is great for your Beechcraft in at least 2 ways. It will reduce The possibility of a broken lower door hinge since it will help to slow the door opening by a strong wind. And, it is much more convenient to use

What a great solution to a problematic door hold open rod. I have just installed a new unit on a Beech Debonair and it was very straight forward. I have also installed the units on a Cessna 175-no problem.
