STI STI-282121-BK Speaker Guard Damage Stopper Black

Overview

The STI STI-282121-BK is a protective wire cage built to shield speakers from vandalism, accidental impact, and theft in institutional and commercial environments. Constructed from 9-gauge steel wire with polyester coating, it measures 28 x 21 x 21 inches and fits larger speaker installations in schools, public facilities, and security-critical spaces where audio equipment sees heavy use or hostile conditions. The black finish blends into standard AV installations without drawing attention.

Compatibility

Designed for mounting around full-range speakers and similar audio equipment in fixed installations. Works in conference rooms, classrooms, emergency communication systems, public address infrastructure, and security command centers. Compatible with standard wall and ceiling mounting hardware. Does not require modification to the speaker itself — the cage mounts independently using supplied fasteners.

Installation Notes

Installation is rapid using included supports, screws, and anchors (no special tools required). The sturdy wire frame allows mounting at multiple angles and positions depending on speaker placement. Steel construction means weight distribution is important — verify wall or ceiling load rating before install. Polyester-coated wire resists corrosion in humid or outdoor-adjacent environments, but the cage is intended for indoor/covered installations. Three-year warranty covers manufacturing defects under normal use; vandalism or abuse does not void coverage if the cage itself remains intact.
