ADC | Low-Height Support Cleat


The design of the aluminium decking cleat allows you to create aluminium decking systems in the tightest of spaces by minimising the height build-up of your system. It can be used when a constricting height build-up restricts the available clearance between the waterproof substrate and the finished floor level; or where additional height is required on metal frame balconies. Joist cleats are height adjustable, catering for falls, or meeting door thresholds while contributing as little as 2mm build-up.

  • Allows for height adjustment to cater for falls or to meet door thresholds
  • Can attach directly to balcony frame for additional height build-up
  • A large base spreads the weight evenly when laid on waterproofed substrates
  • A1 reaction to fire

Spreader Plate

For applications where substrate requires lower point pressure, the 170mm circular spreader plate can be attached to the underside of the pedestal base.

Cleat/Joist Screw

4.2 x 13mm MX8 screw for fixing joist to pedestals. Stainless steel A2 304.

Base shock pad

Base shock-absorbent membrane pads can be installed under the pedestal/support base to enhance acoustic properties, or to provide additional protection to the waterproof system.
