STEP 48 Preload has a fixed cut-out that can operate in conjunction with a lock case’s hook bolt or deadbolt, to block the door’s access control system/reader or door automation. This is desirable in door environments where you want to be able to block the door’s access control system/reader or door automation with, for example, a thumbturn or key.
The combination of STEP’s patented Preload technology and small dimensions provides a lock with high operational reliability and easy installation in almost all door environments.
A common problem is that a door is subjected to pressure, for example, because the door is a little skew or that gravel or snow has gathered at the doorstep. STEP 48 Preload is equipped with STEP’s patented Preload technology that allows the door to be unlocked even if subjected to pressures of up to 40 kg.
To STEP 48 Preload, it is possible to install a dead bolt indication to the electric strike. This indication can be used to automatically block the door’s access control system/reader or door automation when the hook bolt/deadbolt is mechanically locked.
STEP 48 Preload has the same faceplate assortment as STEP 40 Preload, STEP 90 Preload, STEP 98 Preload.
STEP 48 Preload is reversible to fit right- and left hung doors.
