or make it yourself for 20 bucks

Yep, the materials did cost about $20 bucks, 2024-T3 (.062) + 2 hinges
& 2 cargo tie-downs and don't forget the padding and contact cement,
now find someone with a sheet metal shears and brake. Then cut, bend,
trim, rivet, glue, box and ship.....................man are we making
a killing on this?

I have used these for years and some local pilots finally got me to
make up a run, with travel time down to use the shears I have a good
15 hours into making 8 sets for a whopping $42 bucks an hour + gas (my
shop rate is $65/hr)................won't make that mistake again!
