A prefabricated guard house — also called a guard booth or security gatehouse — is a factory-built security structure that arrives fully assembled, with climate control, electrical, and communications systems pre-installed, so it can be set at an entry point and made operational the same day it is delivered. Reynolds Business Systems builds guard booths in both standard and ballistic-rated configurations, with typical delivery running 2-4 weeks from order to a fully assembled unit ready for placement. Ballistic-rated units are built to UL 752, the Underwriters Laboratories standard for bullet-resisting equipment: according to the UL 752 standard, protection is graded across ten numbered levels (Levels 1 through 10) defined by the specific round each is tested against, and Reynolds offers ballistic booths in Levels 1 through 8 — where Level 1 is rated to stop three 9mm handgun rounds, Levels 2 and 3 step up to .357 Magnum and .44 Magnum, and the higher rifle-rated levels cover rounds such as 5.56mm, 7.62mm, and .30-06. Booths are delivered on a flatbed truck and set in position with a crane or forklift, with electrical, data, and HVAC connections typically completed the same day.
