The Krowne 21-190L is a wall faucet mounting kit designed to securely install commercial faucets to a stainless steel sink or backsplash. It ensures a stable, leak-resistant connection between the wall and faucet body, making it essential for proper installation in prep sinks, compartment sinks, and bar areas.

This kit typically includes a pair of locknuts and rubber washers, along with a durable stainless steel mounting bracket that helps reinforce the connection between the faucet and wall-mounted plumbing. It’s built to prevent movement or loosening over time due to heavy usage.

The 21-190L is compatible with most Krowne wall-mount faucets and other commercial faucets that fit standard 1/2" NPT inlets. It’s a universal solution for stabilizing faucets with 8" on-center wall connections.

In high-use kitchens, faucets often become loose or wobbly without a proper mounting bracket. This kit prevents stress on the plumbing, minimizes leaks, and ensures long-term durability by keeping the faucet secure during repeated use.

While the mounting kit itself may not carry NSF certification, it’s manufactured by Krowne, a trusted brand known for NSF-compliant plumbing fixtures and accessories widely used in commercial kitchens.

Yes, the mounting bracket and hardware are designed specifically for use with stainless steel sinks or backsplashes, which are common in commercial kitchens and dish stations.
