Yale Locks & Hardware
B1L Touchscreen and T1L Deadbolts
The Yale Real Living Key Free Push Button B1L and Key Free Touchscreen T1L Deadbolts follow Yale’s introduction last year of the industry’s first cylinderless deadbolts, which offer integrators simplified installation and homeowners superior security. For integrators, installation is a much smoother process without a cylinder since no keying is required. For homeowners, eliminating the keyway provides a more secure product by making the lock pick and bump proof.
