Scaffolging plug “POWERDRIVE“ made of pure nylon is used together
with Hüfner eyebolt “EYE“ Ø 12 mm. A special thread guidance
reduces the turn in power of the eye-bolt up to 35 %. A second
thread guidance at the bottom of the plug avoids stretch forming
of the plug and raises the overall pull out results. Up to 21,5 kN in
brick MZ12/20 were achieved. Hüfner cover cap “RING“ and “KREUZ“
complete the system.
