Locking Ring – Coffee Grounds Disposal Bag Clip for Portafilter Cleaner

Locking Ring – Coffee Grounds Disposal Bag Clip

The NS300Pro Locking Ring secures a coffee grounds disposal bag directly to the underside of the NS300Pro Automatic Portafilter Cleaner, creating a sealed, hands-free grounds collection system. Instead of using a knock box or standing floor bin, this ring-and-bag method lets you clip a standard disposal bag directly beneath the cleaning unit — pulling out the bag when full and replacing it with a fresh one.

Compatible with both NS300Pro installation modes:

• Vertical Mounting Mode: The NS300Pro is mounted above a standing bin or floor-level setup — the locking ring secures the bag between the machine base and the open space below.
  
• Embedded in Countertop Mode: The NS300Pro is flush-mounted into a countertop cutout — the locking ring holds the disposal bag beneath the counter surface for discreet, clean grounds collection.

Who needs this?

This ring is the replacement or spare for the clip included with every NS300Pro unit. If your original locking ring has been lost or damaged, or you want a spare for a second installation point, this is the part to order.

How to use:

1. Open the mouth of a compatible coffee grounds disposal bag
   
2. Stretch it over the locking ring
   
3. Press the ring firmly onto the base outlet of the NS300Pro cleaner
   
4. The bag hangs below — grounds drop in automatically after each cleaning cycle
