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

Specifications:

  • Compatible with:  NS300Pro (all versions)
  • Installation modes: Vertical mount and countertop-embedded
  • Includes: 1 × locking ring
  • Material: Food-safe hard plastic

Frequently Asked Questions

What is the NS300Pro Locking Ring used for?

The locking ring secures a coffee grounds disposal bag directly beneath the NS300Pro Automatic Portafilter Cleaner. The ring holds the bag in position so used coffee grounds can drop into it automatically after each portafilter cleaning cycle.

Is this locking ring a replacement part for the original NS300Pro ring?

Yes. This product is intended as a replacement or spare for the locking ring supplied with the NS300Pro. It is useful if the original ring has been lost or damaged, or if you want an additional ring for another installation point.

How do I attach a coffee grounds disposal bag to the locking ring?

Open the mouth of a compatible disposal bag and stretch it around the locking ring. Press the ring firmly onto the base outlet of the NS300Pro. The bag then hangs beneath the cleaner and receives coffee grounds automatically during operation.

Can the locking ring be used with a vertically mounted NS300Pro?

Yes. The locking ring supports the NS300Pro vertical mounting configuration. In this setup, the ring holds the disposal bag beneath the machine while leaving the bag suspended below the cleaner for direct grounds collection.

Can I use the locking ring with an NS300Pro embedded into a countertop?

Yes. The locking ring also supports countertop-embedded installations. When the NS300Pro is mounted into a countertop cutout, the ring secures the disposal bag underneath the counter so coffee grounds can be collected out of sight.

What happens when the coffee grounds disposal bag becomes full?

Remove the full disposal bag from the locking ring, dispose of the collected coffee grounds, and attach a fresh compatible bag. The locking ring itself can remain part of the NS300Pro grounds disposal setup and be reused with replacement bags.

What material is the NS300Pro Locking Ring made from?

The locking ring is made from food-safe hard plastic. The rigid construction allows the ring to hold a disposal bag securely around the NS300Pro base outlet during repeated coffee grounds collection.

Does the locking ring package include a disposal bag?

No. The product package includes one locking ring. Disposal bags and the NS300Pro Automatic Portafilter Cleaner are separate from this replacement accessory.

Which NS300Pro versions can use this locking ring?

The locking ring is compatible with all NS300Pro versions. It can be used with both supported installation arrangements: vertical mounting and countertop-embedded mounting.
