Industrilas Klima-flex™ 3 latching unit has patented technology that allows for quick mounting in double-skinned doors. When you turn the screw, expanding sleeves are engaged and fix both door skins from the inside. Also available without the expanding sleeves which can be used in double-skinned doors with hard foam insulation. The enlarged outside base of the latching unit together with the corresponding enlarged Klima-flex 3 handle ensures a robust assembly and rigid mounted Klima-flex 3 handle. 

Both inside and outside handles can be mounted onsite, and you can add a rod link or safety catch with no changes to the latching unit. The use of roller cams reduces the friction in the latching operation and increase the gasket compression.

You chose the preferred Klima-flex 3 handle for the outside of the unit and roller cams and other inside options from the Klima-flex 2 range of components, please see related products below.
