The Trans Atlantic (Taco) HVB cylindrical classroom knobset comes in a stainless steel finish and includes an ANSI strike. This classroom door knob has a cylinder on the outside of the door so teachers cannot be locked out from the inside of the classroom. From the inside, the door is always unlocked so students can't get locked in. Constructed for durability, this knobset exceeds ANSI standards for Grade 1, making it the perfect fit for commercial, heavy-duty applications. The knob is prepared for any small format interchangeable core installation for the classroom cylinder, but the cylinder itself is sold separately.
