This product is a new, outright Safety Technology International Stopper® Station flush-mount push button emergency stop fuel pump shutdown with cover and horn. After the activation, the illuminated push button can be turned to reset. The horn is battery powered (batteries are included) and activates upon the opening of the cover. This product comes with a service pin on a lanyard which allows the horn to be silenced during service operations. If you want to order the flush-mount version of this product without the horn, see PMP #62631. Contact PMP for additional discounts on orders of 10 pieces or more. Orders can be a mix of this product and other PMP E-Stops to receive the discount. Made in the USA.
