The Uptec SUPA4 accessory, with 4 mm tabs (ideal to create 4 mm joints), is made of a two-component material: polypropylene for tabs and rubber on the head to guarantee a noise-reducing and anti-slip characteristic. The tabs can be removed using the SUPAK key depending on the floor configuration. SUPA4 can also be used in combination with the aluminum joist. This accessory is to be used in combination with SUPAL and SUPAS pedestals.
