Amerex 11021 questions
What does the Amerex 11021 strap fit?
The nitrogen cylinder mount on the 110 cu. ft. wheeled models 467, 469, 470 and 472, where it is the bottom strap, and the 55 cu. ft. models 491 and 493, where it is the only retaining strap listed.

On the 110 cu. ft. models the Parts Book lists part 11024 as the top strap; the 55 cu. ft. page lists 11021 alone.
What holds the strap in place?
The bolt, washer and wing nut set, Amerex part 16483, listed at the next item on both pages.
Does it fit the Argon Class D units?
No - the Argon page lists part 11020 as the bottom retaining strap and part 10906 as the strap with hose hanger.
What does the store title mean by “saddle clamp”?
That is the store's own wording; the Parts Book calls part 11021 a retaining strap.
Where is it listed in the Parts Book?
Item 17 on printed p.17 (PDF p.19) and item 19 on printed p.19 (PDF p.21).
Why use the genuine Amerex part?
