Medeco MED-X4SFIC – Frequently Asked Questions
1) What is the Medeco X4 Small Format Interchangeable Core used for?

2) Does this core work with existing SFIC hardware?
Yes, the X4 core fits standard SFIC housing prep. Compatible with most commercial grade door hardware accepting small format cores. Verify your hardware accepts standard SFIC dimensions before ordering.
3) What hand or orientation options are available?
SFIC cores are typically universal for hand orientation. The core installs the same regardless of door hand. Cam orientation may vary based on your specific hardware application.
4) What finish does this core have?
Core finish varies by model. The visible portion matches common architectural finishes. Check product specifications for exact finish or contact us to confirm finish compatibility with your hardware.
5) What security grade does the X4 core provide?
Medeco X4 cores offer high security performance with drill resistance and pick protection. Suitable for applications requiring maximum security. Consult security requirements for your specific project needs.
6) How is the 8E keyway different from other keyways?
The 8E keyway is a specific Medeco profile that determines key compatibility. Each keyway accepts only matching key blanks. Verify your existing system keyway before ordering to ensure proper key operation.
7) What parts come with the core?
Cores typically include the cylinder assembly and cam. Control key and operating keys sold separately. Verify included components and key quantities needed for your installation.
8) How do you install an SFIC core?
Insert control key and turn to remove existing core. Insert new X4 core with control key inserted. Turn control key to lock position and remove. Test operation with user keys before completing installation.
9) Do X4 cores require special maintenance?
Use graphite lubricant only in high-security cylinders. Avoid oil-based lubricants that attract dirt. Clean keyway periodically with compressed air. Schedule regular inspection for high-traffic installations.
10) Are there similar Medeco core options available?
Medeco offers various SFIC cores in different keyways and configurations. Browse our Medeco products for alternative cores and matching hardware options.
11) What door weight and thickness does this support?
Core weight capacity depends on the door hardware housing, not the core itself. Verify your door hardware specifications for weight and thickness limits. Standard commercial hardware supports most door applications.
12) What dimensions should I verify before ordering?
Confirm your hardware accepts standard SFIC cores. Check existing keyway marking to match the 8E specification. Verify cam orientation requirements for your specific door hardware application.
