Magnetic seal

A magnetic seal was a form of magnetic technology that could repel blaster bolts and be applied to an entire room. The Ore crawler, Crawler 413-24, had a door that was magnetically sealed, preventing Kanan Jarrus from using his lightsaber to cut his way in to stop Seevor. The cargo container on All Terrain Armored Cargo Transports was magnetically sealed. The doors and walls of the garbage compactors located aboard the Death Star were magnetically sealed, as Corellian smuggler Han Solo discovered when he tried to fire at the hatch of one of the mashers and his blaster bolt ricocheted wildly around the metal room, nearly hitting him and his companions. Vintians could choose to become magnetically sealed.
