Our rigid floor mounted (Pro-Set) lavatory supports are fabricated of epoxy coated heavy gauge steel uprights welded to pre-drilled steel bases and facilitate installation. Adjustable sleeves tighten around the uprights whenheight specifications are met. Support arms coated for acid resistance are bolted to the sleeves and are visisble under the lavatory upon installation. Leveling screws can be adjusted from underneath the arms to ensure a precise installation. Toggle bolts secure the lavatory to the support arms.
