Slot-Klips are the newest option in undermount sink clips. They work in the same way as Sinkits except that they insert into a slot rather than into a drilled hole. Slots can be easily cut with a small diameter diamond blade. Slot-Klips work well in granite, quartz, concrete or any other stone or hard surface material. Just as with Sinkits, Slot-Klips are extremely quick and easy to use.
