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 90 Preload has a performance in its own class.

All our products are developed and manufactured by us, in Sweden. Maximum functionality and reliability are fundamental product features we never compromise on. By choosing STEP, you are selecting premium-quality products designed to deliver exceptional reliability for the long term.
Some environments place particularly high demands on durability and performance. These include door systems exposed to extreme weather changes, heavy wear and tear, or challenging conditions such as salt, moisture, or high preload pressure. Thanks to their functionality and reliability, our products are built to withstand even the toughest environments. Choose STEP – When it has to work.
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 90 Preload is equipped with STEP’s patented Preload technology that allows the door to be unlocked even if subjected to pressures of up to 250 kg.
