Why do these casters look like they belong in Camelot?

In reality, they're custom-built Hamilton casters engineered to guide massive aircraft hangar doors, with each caster rated to support up to 25,000 pounds. Built for a structural steel fabricator, these beauties ride on double-flanged track wheels that keep enormous doors precisely aligned as they roll along steel rails.

The result is a custom caster that combines precision, strength and craftsmanship into one polished package. They're so brilliantly machined, you'd almost hate to hide them beneath a hangar door.

Turns out, Excalibur wasn't the only legend forged from steel.
