When you push open a public restroom stall door, that seemingly insignificant lock knob represents a critical line of defense for privacy and durability. In high-traffic environments, the material strength and installation compatibility of locking components directly determine maintenance cycles. The General Series partition door lock system—including knobs, faceplates, and latches—has become an industry-standard solution through its robust engineering.

These components are zinc-aluminum-copper-magnesium alloy (Zamac) die-castings, renowned for exceptional strength-to-weight ratio and impact resistance. After precision casting, each piece undergoes chrome plating with deep polishing—a dual treatment that provides both corrosion resistance in humid environments and lasting aesthetic appeal.

Key dimensional specifications ensure installation accuracy:

• Knob & Faceplate: Uniform outer diameter of 1-3/4" (44.45mm) with 1-7/32" (30.96mm) inner ring
• Faceplate Architecture: Integrated 1-7/32" (30.96mm) mounting prongs enhance structural stability
• Latch Mechanism: 11/32" (8.73mm) diameter latch with 2-11/32" (59.53mm) total length

Proper selection depends on partition material:

• Model 5190 (Offset Latch): Engineered for powder-coated steel partitions, compensating for metal panel installation tolerances
• Model 5080 (Straight Latch): Optimized for plastic laminate doors, matching material thickness and drilling patterns

The system's standardized design maintains interoperability with Global and Fiat partition systems, streamlining inventory management for facility maintenance teams. When replacing components, verifying door material remains essential for ensuring proper latching functionality. This concealed mechanism exemplifies industrial design that balances security requirements with minimalist aesthetics appropriate for public spaces.
