The Schlage Plymouth Combo Pack brings ANSI/BHMA Grade 1 security to residential doors with adjustable 2-3/8” or 2-3/4” backsets and a keyed-alike system that operates both the deadbolt and entry knob with a single key. Worth it for contractors who need maximum residential security without the complexity of separate keys. At Grade 1 rating, it’s the highest residential security certification available — not marketing fluff, but actual third-party testing that proves resistance to forced entry.
Skip it if you’re looking for budget hardware or smart lock features. This is traditional mechanical security done right, with solid brass construction that’ll outlast the door it’s mounted on. The combo pack shines on primary entries, rental properties where key management matters, and anywhere Grade 1 security justifies the investment.
Installation Flexibility That Reduces Callbacks
The adjustable components save trips to the truck. The backset adjusts between 2-3/8” or 2-3/4”, eliminating the guessing game when you’re matching existing door prep. The adjustable/universal latch means one SKU covers most residential applications.
Compatible with standard door pre-drills (2-1/2” bore) and works on wood, metal, or fiberglass doors. That universality matters when you’re stocking inventory or loading the truck for a day’s installations. The installation requires just a Phillips screwdriver, with optional drill if holes aren’t pre-drilled — no specialty tools or jigs needed.

The universal fit for right-handed or left-handed doors eliminates another potential ordering error. One combo pack, multiple applications. That’s efficiency that translates to profit.
Keyed-Alike Convenience Without Compromise
The one-key convenience means the same key operates both deadbolt and knob. Sounds basic until you’re managing a rental property or dealing with elderly clients who struggle with multiple keys. The system can be keyed alike with other Schlage C-keyway locks, allowing you to expand the system across multiple entries.
The combo pack includes 1 single-cylinder deadbolt assembly, 1 keyed entry Plymouth knob (or lever in some variants), 2 keys (keyed alike), mounting hardware (screws, strikes, latches), and installation instructions. Everything needed for a complete entry installation arrives in one package.
Build Quality That Justifies the Investment
Solid brass construction isn’t cheap, but it handles Montana’s temperature swings without the expansion issues you get with pot metal hardware. The Grade 1 deadbolt provides maximum security — tested to withstand 250,000 cycles, 6 door strikes, and a 360-pound force test. Resistant to picking and bumping adds real-world security against common attack methods.
Available in Bright Brass, Matte Black, Satin Nickel, Polished Chrome, and Aged Bronze finishes. The variety lets you match existing hardware or architectural styles without compromising security. The Limited Lifetime Warranty covers both the mechanical operation and the finish — Schlage stands behind both function and appearance.
Customer satisfaction backs up the specs. Ratings include 4.5 stars from 664 reviews (Home Depot Matte Black), 4.4 stars from 604 reviews (Home Depot Bright Brass), 4.4 stars from 274 reviews (Lowe’s Matte Black), and 4.9 stars from 66 reviews on Schlage.com. Those numbers reflect real-world performance across hundreds of installations.
The Bottom Line
The Plymouth Combo Pack delivers genuine Grade 1 security with installation flexibility that matters. The adjustable backset, universal components, and keyed-alike convenience reduce complexity without sacrificing protection. At this security level, you’re protecting more than property — you’re delivering peace of mind.
The solid brass construction and lifetime warranty mean fewer callbacks and happier customers. For primary entries, rental properties, or any application where maximum residential security matters, the Plymouth Combo Pack earns its place in your installation lineup.
