1：World’s Only Keyless Solution: The first 100% mechanical keypad for bottom rails. Perfect for business owners who want to ditch the keys without sacrificing reliability.
2：SFIC Key Override: Features a Small Format Interchangeable Core (SFIC). This allows for seamless integration into existing master-key systems—a must-have for professional facility managers.
3：Direct "No-Drill" Retrofit: A parallel, drop-in replacement for CRL 777S, FHC R777, and ILCO BRL. Fits standard rail cutouts perfectly—no drilling or rail modification required.
4：Rapid Code Management: The SK35 is engineered for high-turnover environments. Its modular design makes changing access codes faster and easier than any other mechanical lock on the market.
5：Enhanced Security: Supports customizable 3-to-5 digit codes for increased combinations and peace of mind.
6：Note for Pros: For retrofitting on doors without a threshold step, unhinging the glass door is required to remove the old mortise. Ideal for door manufacturers and service crews.
