Z1035 and Z1036 FLOOR DRAIN INSTALLATION STABILIZER
For Flying Form Construction
The Zurn Drain Installation Stabilizer is a unique support plate designed to secure a drain in place and provide adjustment, rigidity, and
strength during the drain installation process.
The main objectives for the Drain Installation Stabilizer are as follows:
a) To provide a means of pre-assembling the drain to a known
rough-in height. If the floor thickness is already known, the drain
and Installation Stabilizer can be conveniently pre-assembled
away from the job site, and quickly placed and leveled in the
correct location at the job site, saving labor costs.
b) To locate and secure the drain in place and keep it in position
prior to concrete pour. The Installation Stabilizer will help resist
the drain from tipping, tilting, or being knocked over during
construction and concrete pour.
c) To allow height and level adjustments of the drain to meet the
finished floor.
d) To support any reasonable excess weight that may be placed on
the drain before the concrete is poured.
e) To create an open pocket on the underside of the plate, allowing
for attachment of the waste line piping after a concrete pour.
How To Use the Drain Installation Stabilizer
The Installation Stabilizer is constructed of galvanized steel plate and is designed to be used with 8-3/8" diameter, 12" diameter, and 15"
diameter drain bodies (2", 3", and 4" No-Hub and Neo-Loc outlets).
Four lengths of all-thread rod are attached to the drain body by inserting and tightening into the tapped holes located on the underside of the
drain body. The stabilizer plate is then connected to the all-thread rod by use of flanged nuts, above and below the plate. Adjusting the
placement of the nuts changes the rough-in height of the drain. Once the proper height is obtained, the nuts are tightened against the plate.
Any excess rod is trimmed off and a stub of pipe is then connected to the drain body and allowed to extend through the center hole of the
plate. The assembly is then nailed down to the concrete form.
When concrete is poured around the drain, the plate creates a pocket on the underside of the slab. When the concrete is set and the forms
are stripped away, the visible result is a stub of pipe protruding through the underside of the slab. The remaining drain line can then be
connected to this stub of pipe.
