Bolton Gate's Escalator horizontal shutter is ideally suited to provide fire compartmentation between floors of a shop or store where escalators, travelators or stairwells entail a floor aperture. Available in various configurations, the design parameters are versatile allowing the shutter to be incorporated within light wells, plant rooms or special tank covers. The Escalator shutter has been successfully fire tested satisfying the requirements of BS 476 Part 22 for stability and integrity up to 4 hours and has been certified by LPCB. Prior to delivery, each shutter is assembled, pre wired and factory tested to eliminate commissioning problems.
