Our sturdy floor mounted (Pro-Set) lavatory supports for back-to-back lavatories are fabricated of epoxy coated heavy gauge tubular steel uprights welded to pre-drilled steel bases. Adjustable coated cast iron sleeves are tightened around the uprights when height specifications are met. Sleeves are internally threaded to accept horizontal adjustment of the threaded arms, arm lock nuts and chrome plated escutcheons. To ensure that the lavatory is solidly affixed to the concealed support arms, our Sure-set locking device easily adjusts from underneath the lavatory to firmly grip its inner wall while leveling screws ensure a precise installation.
