STI KIT-102722-R 5/8" Spacer for Stopper® Stations
Overview
The STI KIT-102722-R is a 5/8" offset spacer engineered for Stopper® emergency communication and notification stations. This accessory addresses a common installation challenge: when mounting Stopper® units in recessed or surface-mounted configurations, you need predictable standoff distance to ensure the lock/strike mechanism aligns correctly with its corresponding strike plate. The KIT-102722-R maintains that critical clearance, keeping the 9VDC-powered strike in proper engagement regardless of wall thickness or mounting surface profile.
Why This Spacer Matters
Emergency notification stations live on walls where consistency matters. Building finishes vary—drywall, plaster, masonry, composite panels—and backing hardware sits at different depths. Without a precision spacer, strike plates can sit too deep or proud of the mounting surface, causing mechanical misalignment and erratic lock/unlock cycles. The 5/8" dimension is standard across many Stopper® installations, making this kit a drop-in solution for retrofit or new deployment where spacing requirements demand offset mounting.
Proper spacing directly affects reliability. A strike that engages consistently runs longer and generates fewer false-alarm service calls. In educational facilities, corporate emergency response systems, and public safety environments, that reliability translates to confidence in the system when it's needed.
Key Features
- 5/8" Standoff Dimension: Provides predictable offset mounting depth, ensuring lock/strike mechanism alignment across varied mounting surfaces and wall configurations.
- 9VDC Stopper® Compatibility: Designed for standard 9VDC-powered Stopper® emergency stations used in mass notification and emergency communication deployments.
- Mechanical Strike Support: Maintains critical clearance for the lock/strike solenoid to engage the strike plate without binding or misalignment.
- Installation Simplicity: Drop-in offset component—no special tools or reconfiguration of the main station required.
Integration & Compatibility
This spacer integrates directly with the STI Stopper® station family, where it bridges the gap between mounting surface and the station's strike mechanism. It's especially valuable in retrofits where existing wall conditions or architectural features (recessed frames, trim, panel systems) require a predictable standoff. Compatible with all standard 9VDC Stopper® configurations used across educational institutions, corporate facilities, and public safety deployments.
If you're designing an emergency notification system architecture, verify the mounting surface profile and wall thickness early—this component can save field troubleshooting time and repeat visits.
Frequently Asked Questions
Q: Is the KIT-102722-R compatible with all Stopper® models?
A: This spacer is designed for 9VDC Stopper® systems. Verify your specific Stopper® model's mounting requirements in your installation guide—the 5/8" offset is standard across the primary commercial Stopper® line.
Q: Can I stack multiple spacers for greater offset?
A: Yes, though this should be done with deliberate spacing calculations. Exceeding the designed standoff can affect strike engagement and solenoid performance. Consult STI documentation for maximum recommended offset.
Q: What if my wall is thicker or thinner than 5/8"?
A: If you need a different standoff, contact the manufacturer or your integrator for alternate spacer options. Using an undersized spacer risks strike misalignment; oversized can reduce solenoid engagement force.
Q: Does this spacer require any tools to install?
A: Installation is straightforward—it positions between the mounting surface and the Stopper® unit. Use the same fasteners your Stopper® installation already specifies.

The KIT-102722-R is a purpose-built offset spacer that solves a real installation headache: achieving repeatable lock/strike alignment across variable mounting surfaces. In emergency notification deployments, mechanical reliability is non-negotiable, and the 5/8" standoff dimension is the standard workhorse in the Stopper® family. This isn't a luxury—it's insurance against field troubleshooting.
Technical Highlights:
- 5/8" Standoff Tolerance: Maintains critical clearance between the mounting surface and the 9VDC strike mechanism, ensuring consistent solenoid engagement without binding.
- Strike Mechanism Compatibility: Designed expressly for the lock/strike operation at 9VDC, preserving the electromagnetic force required for reliable door control.
- Architectural Flexibility: Absorbs variability in wall thickness, panel depth, and mounting frame profile—common across educational and corporate facility builds.
Deployment Considerations:
- Verify mounting surface profile and wall construction before ordering. Drywall, masonry, and composite panels each present different backing conditions.
- Strike mechanism engagement depends on precise standoff. Undersizing the spacer risks misalignment and solenoid chatter; oversizing reduces electromagnetic force transmission.
In large-scale emergency notification rollouts across multi-building campuses or corporate complexes, having the right spacer kit on hand eliminates field delays. The KIT-102722-R is specifically engineered for Stopper® systems operating at 9VDC, making it the correct choice whenever your mounting configuration requires predictable offset.
