Portable A4
The Portable A4 System consists of 22mm solid hardwood floor boards, preassembled into light weight, hand carried panels. Each floor panel has several prefixed battens mounted with soft rubber pads to provide correct shock absorption and resilience.
Each floor panel is easily locked securely into position with a pre-mounted assembling fitting. Lengthwise the panels have a tongue and groove connection and at ends the panels are joined using loose tongues.
A supporting and protecting edge reducer forms a strong edge for the perimeter of the floor.
INSTALL TWICE AS FAST
For faster and more flexible installation ask for Junckers CenterRow Panels that makes two way installation possible.
EASY TRANSPORTATION AND STORAGE
Junckers custom designed storage carts make transportation and storage of the panels easy.
