Hager 3570 26D Wtn Classroom Cylindrical Lock

Product Description

The HAGER 3570 26D WTN is a Grade 2 classroom cylindrical lockset designed for institutional and light commercial door hardware applications. It features a conventional cylinder, a Withnell lever with rose trim, and a satin chrome (26D) finish. The classroom function keeps the exterior lever locked by default, allowing egress from the interior at all times while restricting entry from outside unless unlocked by key. This lockset is installed by licensed locksmiths, general contractors, or door hardware specialists during new construction or retrofit projects.

This lockset is suited for classroom doors, office suites, and similar interior or vestibule door applications where controlled access is required. The classroom lock function is a common specification in K-12 educational facilities and institutional buildings where quick lockdown capability is a priority. The satin chrome finish coordinates with standard commercial hardware schedules.
