The concept of the MB 850 series is based on the principle of pressure / expansion. Each plug consists of a ball as an expanding element and a bowl-shaped expansion sleeve. By pushing the ball into the sleeve, the sleeve widens outwards. The teeth on the outside of the housing dig into the base material and ensure a secure anchorage. The ball is properly hammered when it is flush with the top of the case or slightly below it. The upper part of the case contracts slightly and prevents the ball from firing.
