TECHNICAL SPECIFICATIONS:
Culwell® Flange 4-in Hub Glue-In models are for tile applications with impermeable floor-covering membranes from 30 to 100 mils thick or
without a membrane when the flange is recessed below the finished floor. For new construction or remodeling. These flanges attach to the
sanitary piping system using conventional means that are standard in the industry and are designed to:
Allow the flange to seal to the floor with its flat flush surface design and seal to a water barrier membrane to prevent water leakage into
the subfloor thereby protecting the property from damage.
Solvent weld over 4 inch Schedule 40 DWV pipe.
Additional features include:
Eight countersunk holes for secure attachment of the flange to the floor.
One-of-a-kind nylon clamping ring for superior strength and durability to prevent
the need for repair or replacement in the future, backed by Culnat’s exclusive
LIMITED LIFETIME WARRANTY.
Uniquely engineered flat sealing surface for maximum contact between the flange and floor. Clamping ring that compresses an
elastomeric sealing gasket against the floor-covering membrane liner to ensure a water-tight seal, while also engaging with the gasket to
keep the closet bolts in place for ease of toilet installation.
Ideal for:
Wet rooms - Small spaces - Multi-floor
Concrete - Bariatric/Disability
Commercial - Residential
