Hang It Up Side View Helmet Wall Display Rack

Will this produce work to display a football helmet?

I need 4 side view football helmet wall mounts. This seller's inventory says only 2 available. Any ideas where I can find vendor with 4 available?

Will this hold a motorcycle helmet securely? Can I hang a motorcycle jacket (on a clothes hanger of course) on it as well?

what are the dimensions? How far does it stick out from wall? how high?
