Installation
Three steps. No silicone gymnastics.
Pick your variant below for the install walkthrough. Cut, seat, mount — and onto the next one.
01Cut. Slide. A single slit cut; the corrugated base slides under the upper sheet and locks against the rib.
02Seat. Fix. Base sits flush; side flanges screw down. The flat platform is ready for the seal.
03Mount. Move on. Mount the rubber boot on the flat platform. No bending, no silicone marathons.
