Isostep is a powder coated aluminium substructure with an integrated rubber granules insert. With an overall height of only 23 mm, this profile is the perfect solution with for low installation heights. Thanks to its low height, this rail is perfectly suited for use on level surfaces such as concrete floors, plaster and tiles, and it can be installed in places with small installation heights (e.g. deck or balcony door). With the TERRACON fastening systems, deck surfaces can be installed without the need for additional construction.

Do not bolt the rail directly onto the decking boards. Always use a spacer (TerraFlex, Clipper or Terrafix).!
