Overview
Optimize pull-station installations with the Safety Technology International STI 3100 conduit spacer — a clear, purpose-built mounting device that adds two inches of depth to Stopper II pull stations for tidy, code-conscious wiring. The transparent polycarbonate construction is UV-stabilized for lasting clarity and allows quick visual inspection during service, reducing troubleshooting time for security and fire monitoring teams. Integrated top and bottom knockouts accommodate both 1/2" and 3/4" rigid conduit, and included fill pieces keep the enclosure sealed and professional when conduit isn’t present. At 8.5" H x 5.5" W x 2" D and designed for surface-mount applications, the STI 3100 simplifies retrofits and new installs in fire mounting & enclosures used in security, surveillance, and life-safety systems. Compatible with the Stopper II product line and adaptable to weatherized builds when combined with appropriate gaskets, this spacer helps maintain system integrity while speeding installation.
