These have been kicking around my shop for a while and it’s time for them to go. These are shoulder harness mounts for fixed (non-retractable) harnesses. These are nicely made in a machine shop.

There is a 337 somewhere out there for this design.

Steve,

I'll accept your kind offer, thank you. sending a PM

These were originally provided by a company named Safety Limited. The kit included brackets, rivets, and shoulder harness and a sample 337. It is interesting that the brackets shown are not drilled for screws and rivets, but no big deal.

They were installed on a 337 as there is no STC for the installation. If someone purchases them, I have a copy of the Safety Limited paperwork including a sample 337.

I would suggest discussing approval with your local FSDO before punching holes in your airplane as they may send you to a DER for approval. Get ready for a long wait for approval.

Please PM me through this site if you need paperwork.

Thanks Tom. They are in the mail to Robert. Fortunately he is familiar with the 337 and I’m sure the info you provided will be helpful.

Tom -

Just sent you a PM for the supporting documentation - Thanks.
Robert
