Poppit® Panel Fastening redefines "quick fit" in ceiling and wall panel fastening and demount. A male and female Poppit are glued onto two panels at suitable intervals. When mated, the stainless steel ball of the male Poppit® clicks firmly into a specially-formulated high-impact polycarbonate female socket, whose jaws grip the ball to form a precision-engineered ball & socket joint without squeaks or rattles. This adhesive-based procedure guarantees exact alignment, simplifies the mounting of internal/external panels & cladding, and is instantly demountable. Male Disk Poppits® are available in galvanized steel and stainless steel. Male Screw Poppits® are available in stainless steel with your choice of a self-drilling or self-tapping screw.
