KOENIG EXPANDER® SERIES LK 950 – OVERVIEW

pull type expander seal
SERIES LK 950 Expander Plug
Pull-style expander seals use an integrated mandrel to insert the expander plug into a drilled hole. This type of KOENIG EXPANDER® Series LK 950 plug does not require the hole to be counter-bored, and is often used for angled channels or installations with difficult orientations. They are ideal for installations with space or weight constraints.
