Thank you to everyone who responded!

I expect that Cushcraft would send the same parts as supplied with a
new beam. They were not very robust.
The traps are 1.625" so it looks like DX Engineering is not an option
based on what I see on the website. If Caplugs do small orders, that
might be the way to go.

Kevin -

Yes, you have many alternatives.
Cushcraft did offer stainless hardware kit for the older A3 beams (before
A3S) as well as a plastic replacement kit.

What ever you select -- make sure it is UV resistant !!

Other suppliers -

Car Plugs for Tubing -- they have everything for tubing caps !
COF series will likely work !

Seal the ends of your boom, tubing or pipe with our vinyl caps. Sizes fit
from 1/8 in. to 3 in.O.D. By keeping moisture out, you can reduce corrosion.
For those in colder climates, you can prevent water from collecting in the
tube that might freeze and split the tube.

Made from a strong UV rated material, they will withstand the abuse of
nature and keep your installation safe and good-looking for years.

Good luck with it.
