Schlage 80-035 Small Format Interchangeable Construction Core
The Schlage 80-035 is a Small Format Interchangeable Core (SFIC) designed specifically for the construction phase of a commercial keying project. Construction cores allow a building to be secured during construction with a temporary master key, then swapped out for permanent cores at project completion — without removing the lockset from the door. The 80-035 is available in Brown or Green keyway to match your project's keying convention.
Key Features
- Small Format Interchangeable Core (SFIC) — plug diameter smaller than the standard 1/2" format for compatibility with SFIC-ready hardware
- Construction-phase core — enables temporary keying during build-out; swap to permanent core at handover without removing hardware
- Available in Brown Keyway and Green Keyway — select the keyway color that matches your master key system
- Certified Schlage replacement part — manufactured to original Schlage specifications
- Finish-specific design — confirm keyway color selection before ordering; cores are not interchangeable between keyway families
- Built from commercial-grade materials for durability in high-traffic applications
Typical Applications
- Commercial new construction and tenant improvement projects
- Property managers and GCs managing phased keying programs
- Locksmiths servicing Schlage SFIC master key systems
- Replacement of worn or lost construction cores in existing SFIC hardware
Compatibility Note
The 80-035 is designed for use with Schlage SFIC-compatible locksets and cylinders. Verify that your existing hardware accepts the Small Format Interchangeable Core before ordering. If you are unsure of compatibility, contact ZenSupply — we can help confirm the right core for your system.
