Our rigid floor mounted (Pro-Set) supports for high back enameled iron lavatories are fabricated of epoxy coated heavy gauge steel uprights welded to pre-drilled steel bases. Adjustable sleeves clamp onto the uprights when height specifications are met. Support arms coated for acid resistance are bolted to the sleeves and are visible under the lavatory upon installation. Leveling screws can be adjusted from underneath the arms to ensure a precise installation.
