Insert Clamping Flange
$8.95
Waterproofing in a curbless shower installation is only as strong as its weakest connection point, and the area right around the drain is the most vulnerable spot in the entire shower floor. That’s where the clamping flange does its most important work.
The VIM Insert Clamping Flange is the component in the Level Entry Shower Drain Assembly that clamps the waterproofing membrane firmly between the drain body and the insert, creating a secure, compression sealed connection right at the drain opening. Without it, even the best waterproofing membrane in the world is just sitting loose at the most water intensive spot in the shower.
It’s a precise, purpose built part, and in a system with zero reported waterproofing failures since 2008, every component earns its place.
What the Insert Clamping Flange Does
The shower insert clamping flange serves a specific and essential function in the VIM LES Drain Assembly sequence:
- It sandwiches the waterproofing membrane between itself and the drain cup, mechanically securing the membrane at the drain opening rather than relying on adhesive alone
- It creates a compression seal that keeps water from finding a path between the membrane and the drain body, the most common failure point in curbless shower waterproofing
- It locks the insert in position within the drain assembly, keeping everything aligned and stable under the daily demands of a working shower
- It integrates with the full assembly, sized at 6.25″ × 6.25″ × 1.25″, and it’s engineered to sit precisely within the VIM drain system, not adapted from a generic component
This curbless shower clamping flange makes the connection between the waterproofing layer and the drain assembly truly secure, not just sealed, but mechanically clamped.
Why This Component Matters in a Level Entry Shower
In a traditional shower with a curb, water is largely contained by the threshold. In a curbless shower, the floor and drain are the entire waterproofing system; there’s no curb to catch what the membrane misses. That raises the stakes on every component in the drain assembly, and especially on the clamping flange for drain connections.
The VIM clamping flange is engineered with that reality in mind. It’s part of a drain assembly system that’s been code approved, field tested, and refined by the same master plumber and tile setter who pioneered our Level Entry Shower System™.
If you need the complete drain assembly without sourcing parts individually, the VIM Drain Kit includes the insert clamping flange along with every other component and specialty tool required for a full installation. For step by step installation guidance, visit VIM’s installation resources page.
Frequently Asked Questions
Is the Insert Clamping Flange included in the VIM Drain Kit?
Yes, it’s included as a standard component in the complete VIM Drain Kit. This page is for installers who need to order or replace it separately.
Why can't I use a generic clamping flange?
The VIM Insert Clamping Flange is dimensionally matched to the LES Drain Assembly. A generic substitute may not compress the waterproofing membrane correctly or align with the drain cup, compromising the seal at the most critical point in the shower floor.
At what point in the installation is the clamping flange installed?
The Insert Clamping Flange is installed during the drain assembly stage, after the waterproofing membrane has been applied. VIM’s installation resources cover the full sequence in detail.
