TL4 Series Interior Locks

ANSI/BHMA 156.2 Grade 2 Tubular Lever Sets

Our TL4 Latch is commercial grade with a 28 degree latch retraction to meet ADA requirements; pair with designer INOX trim for your most beautiful options. Also available with a 3-hour fire-rated latch.

Features

INOX TL4 series interior latch sets consist of beautifully designed trim made of stainless steel or forged brass, a spring-assisted interlocking chassis, and a commercial grade tubular latch, making it the perfect choice for high-end residential, mixed use, and hotel or other hospitality openings.

A 28 degree short retraction latch design makes for easier operation, and hardened steel hubs inside the latch prevent lever sag for extended life of the set

Meets ANSI/BHMA Grade 2 Standards. All lever sets meet ANSI A117.1 Accessibility (ADA Compliant). UL10B/UL10C fire rated TL4 latch available.
