Adams Rite 4900-26-201-628 Cylinder, Deadlatch

Designed for secure, flexible access control in commercial and institutional settings, the Adams Rite by ASSA ABLOY 4900-26-201-628 electrified deadlatch delivers durable performance where security matters. The heavy-duty steel body with corrosion-resistant plating and a stainless steel deadlock design resists wear and prevents loiding (case-knife) attacks, reducing downtime and maintenance. Measuring 7/8" x 5-13/16" with depth varying by backset, the 4900 fits common mortise pockets and retrofit installations—standard strike 4902 is supplied for flat jambs, with other strike options available for paired or center-hung doors. The reverse-turn key feature lets the bolt remain fully retracted for free-swinging operation during peak traffic, making it ideal for retail, healthcare or education facilities. Supplied with flat and radius faceplates, strike plate and mounting screws, the unit simplifies installation and integrates with electrified access control, monitoring and security systems used alongside surveillance infrastructure. For robust door security with flexible traffic management, specify the Adams Rite 4900 electrified deadlatch for your next project or retrofit.
