Heat Bulb Guards in the US

I have been searching online for heat bulb guards for sale in the US, and everything I come across is in the UK and most won't ship, if they do it's rediculously expensive. Does anyone have a source for these stateside? I'd like to put on in my BTS's tank even though he doesn't climb and can't reach the bulb I'm too paranoid to have an exposed bulb in the cage.

All the ones I have or seen have been made, mostly with chicken wire. I never looked at any reptile shows but i'm sure you could probably find one.
