Product Description

The concept of the MB 850 Koenig Expander Series is that of a pressure/expand principle. Each plug consists of a ball, as the expanding element, and a cup-shaped expansion sleeve. Forcing the ball into the sleeve causes the sleeve to expand outward. The serrations on the outside of the sleeve dig into the base material to provide a secure anchorage. The ball is set when it is flush with or slightly below the top of the sleeve. The top of the sleeve constricts slightly and prevents the ball from coming out.
