Optimized performance with HPR® technology

Electric strikes in the Preload series have since the launch in 2012 become the obvious choice and thus Sweden’s most popular electric strike.

With experience from hundreds of thousands of products sold, StepLock has now taken the product series another big step forward with the new Preload HPR®. With its fine material selection and these optimizations, STEP 40 Preload has a performance in its own class.

  • 250 kg Preload technology for a reliable function
  • 1 200 kg breaking strength
  • Improved weather protection
  • Factory tested to 1,500,000 cycles
  • Protection against tampering

The result speaks for itselves. The HPR® technology gives the electric strikes an unrivaled functionality and operational reliability.

Great flexibility with adjustable functionality

STEP 40 Preload is available in fail-safe, fail-secure or adjustable functionality. With the adjustable option, you can select and switch between fail-safe and fail-secure modes during installation. This, of course, provides significant flexibility and also reduces handling costs.

The lock is also reversible, making it suitable for both right- and left-handed doors.

Choose whether the lock shall come with or without bolt contact.

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 30 Preload is equipped with STEP’s patented Preload technology that allows the door to unlock, even if subjected to pressures of up to 250 kg.

  • Seals and pressure differences – The Preload function enables the door to always be unlocked even when the door lock is tensioned against the electric strike.
  • Door automation – The Preload function combined with rapid unlocking means that the door opens quickly and without risk of becoming stuck.
  • Evacuation door – The Preload function ensures that a fire alarm can release the lock, despite pressure against the door by crowds, seals, pressure differences or warped doors.
  • Manipulation protection – The Preload function Resists influences in the form of manipulation and external violence.
