Can the Vapor Pin® sampling device be used in slabs of any thickness?

The Vapor Pin® sampling device was designed to be used in slabs that are at least three inches thick. If the Vapor Pin® sampling device will be installed as a flush mount, we suggest that the slab be at least four inches thick. Because the Vapor Pin® sampling device does not have to extend to the bottom of the slab, there is no maximum slab thickness, provided your drill bit is long enough to drill into sub-slab. A 5/8-inch drill bit with a length of 24 inches covers most situations.
