The OATEY COMPANY 41602 is a 40 mil black PVC dam corner designed for use at the junction of a curb and door jamb in wet-area installations. This part provides a watertight seal at one of the most vulnerable transition points in a shower or wet room floor assembly. The universal design accommodates both right-hand and left-hand corner configurations, reducing the need for separate left and right SKUs on the job. Plumbers and tile setters typically install this component during the waterproofing stage of a shower pan build-out, before tile or mortar bed placement.
The 41602 is suited for residential and light commercial shower and wet room construction where a clamping or bonded curb system meets a door jamb. It is used in conjunction with PVC shower pan liner material to create a continuous waterproof membrane at the corner transition. The universal left-right geometry makes it practical for single-family bathrooms as well as multi-unit residential projects where both corner orientations are needed on the same job.
Designed as an OEM-style accessory for use with 40 mil PVC shower pan liner systems at curb and door jamb corner transitions. No specific model or system family compatibility data was provided in the product input.
Installation is typically performed by a licensed plumber or experienced tile setter during the waterproofing rough-in phase. Power or water supply does not apply to this component, but all surrounding framing and substrate must be clean, dry, and free of debris before bonding. The corner should be solvent-welded or adhered to the field liner per the liner manufacturer's instructions to maintain a continuous waterproof membrane. Follow applicable local plumbing codes and manufacturer guidelines for liner overlap and seam bonding.
