Surface mounted lock STEP 8

– A surface mounted lock in minimal design

STEP 8 is a perfect solution where a lock is to be installed afterwards or where you can not or do not want to install a recessed lock, for example, due to space considerations, in doors where there is asbestos or in doors with high cultural value.

The lock can be used as a replacement for magnetic locks and is combined with door automation and/or fire alarms. It can be mounted vertically or horizontally on both single and double doors.

STEP’s unique Preload-technology combined with minimal measurements and stainless steel provides STEP 8 with a reliable and stylish design.

Quick and easy assembly

The installation is very easy. No changes need to be made to the existing recess.

STEP’s patented Preload-technology

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 8 Secure is equipped with STEP’s patented Preload technology that allows the door to unlock, even if subjected to pressures
of up to 150 kg.

Wide range of applications

STEP 8 consists of two sturdy parts, a hook mounted on the door leaf and and an electrical strike in a bracket mounted directly on the underside of the frame.

Depending on where STEP 8 is supposed to be mounted there are several different accessiories too choose from.

Fail safe function for doors with evacuation requirements

With the fail safe function, STEP 8 is used for evacuation doors with evacuation terminals or emergency opening buttons. The lock can withstand a preload of up to 150 kg, which allows a safe evacuation. STEP 8 is also available with fail secure function.
