After reading Jim McGauhey's blog about his encounter with turbulence and canopy damage due to unsecured cargo, I have resolved to install tie-down rings in the baggage area of my STOL 750!  Although I don't have a canopy to potentially damage, I do have windows, a windscreen, and most importantly, my head!

However,  when I looked for reasonably-small tie-down rings ("reasonably small" in that I'm limited to only securing about 40 lbs. of cargo in my STOL 750), it seems the smaller the ring, the more difficult it is to find an "aviation quality" tie-down ring - and preferably, one that is recessed when not in use.

I did find these tie-down rings on Amazon which are interesting - when not in use, you can easily remove the ring entirely, leaving only the low-profile mount.

Any recommendations, sources, photos, etc. for a quality, lightweight tie-down ring?

John,

Look here https://www.mcmaster.com/tie-down-rings

McMaster Carr has some.

Interesting - McMaster-Carr has a low-profile aluminum tie-down base identical to the one on Amazon.  However, McMaster-Carr wants more $$ for one (1) base than Amazon charges for a complete set of 4 bases with the removable rings included, too!!!

I'm just not seeing these aluminum ones (on either Amazon or McMaster). Can you provide a link? Thanks.

Ken,

Amazon link: 4 Pack Round Anchor Point Tie Down Kit (Set of 4 with bases and stainless rings, $20.88 with Prime delivery included)

McMaster-Carr appears to have the identical item, #39695T35 for the base and #39695T51 for the ring, however, the ring is zinc-plated steel and not stainless.  A set of 4 bases and rings would be about $100 and they don't include the reinforcing plates or mounting hardware!

John

Thank John.

It is not quite what you are asking about, but my solution was to install tie down points during the build process.  It was a fairly cheap way to add anchor points in the baggage compartment.  Here is a link to the pictures Baggage tie down

I look forward to seeing what you come up with for your solution.

I was trying to figure out the same thing with respect to tie downs. I think what you did is what I will do as well.

Where did you get those tie down loops ? I like that solution coupled with the cargo net thing someone else posted

Ordinary "pull" door handles would work, similar to these, perhaps with an aluminum backing plate.

Or, for those of us with BRS installations, the rear bridle brackets are already right there.

I've seen these on Overton Boat hardware.

Footman loops (with a backing plate) and a webbing loop are another option.  The webbing loops can be customized, easily removed and easy to thread or hook with tie down lines.

Here are a a couple pics of one of our tie down solutions on the helicopter.
