Top lift pedestal system with adjustment collar and baseplate. Designed to snap-lock to the underside of each decking fixing rail, typically at 500 mm centres, dependent on rail depth and the anticipated live loads.

Features and benefits:

  • Quick installation.
  • Manufactured from filled polypropylene (100% recycled).
  • Acid and alkali resistant.
  • Resistant to atmospheric compounds.
  • Functional in temperatures between -30°C and 60°C.
  • Meets the requirements of the French Unified Codes of Practice, DTU 51-4, for wood decks.

Height adjustment range:

  • Without risers: 35–55 mm.
  • With one pair of risers: 35–100 mm.
  • With two pairs of risers: 35–145 mm.
  • With three pairs of risers: 35–190 mm.


Can be installed directly onto stable substrates such as concrete, roof terraces with waterproofing, and existing terrace surfaces.

If the pedestal is placed on stable, compacted natural soil, a geotextile underlay is recommended to prevent vegetation growth and limit water in-flow under the deck. If the pedestal is installed on turf, remove the growth layer and lay geotextile under the pedestals to prevent grass from growing back.
