Koenig MB Series Expander

Boneham Stand: K34

The concept behind the MB 600 Series Expander Plug is that of a pressure/expand principle. Each plug consists of a ball 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. This provides a high pressure seal in drilled holes, making the Expander ideal for hydraulic applications as well as low pressure applications.
