If you have ever tried to tap a hole in Aluminum 1-1/4" deep you know how
difficult it can be.
After many builders asking to buy taps and for guidance in accurately tapping
the AEX tie down block for the RVs, this is our solution. We have set up a
fixture in our machine shop to tap the aluminum extrusion supplied by Vans. This
way the thread will be straight in the block and builders do not have to buy a
tool for this one task. Combined with our popular forged tie down rings this
makes for a quick fix to a tricky problem.
If you send the three AEX tie down blocks from your kit to us, we will give
you a credit of $8.00. Combine that with the $12.00 in the cost of the tie
down rings alone and it only costs $12.00 to have it done for you. That is
cheaper than a drill bit, tap, and tap handle, and it's guaranteed that you
won't mess up your parts.

highly visible either on the wing or in the grass)
