Which truss rod wrench for this Martin?

[Tico]

It's a 2015 Martin 000-15M with truss rod access through the body.

There is a brace in the way in which Martin drilled an access hole.
A pencil went in the hole over three inches before hitting the neck block.

Where can I buy such a long wrench, and what size in mm?

Should be a 5mm allen/hex wrench.

Just do a search for ''Martin Truss Rod Wrench''. You'll find them available all over the place.

Truss rod access is not on the head, rather it's in the body.
The wrench must be long because there is a brace in the way that Martin drilled a hole in. See pic below.

I put a chop stick in the hole and it went in over three inches before hitting the neck block.

5mm long allen. Home Depot has them.

Just FYI (and anyone else who isn’t aware), Martin do not supply a truss-rod wrench with their instruments.

Thanks all!

This 90 degree truss rod works great, highly recommended.
