$722 Per Bundle

One bundle includes 1 hinge, 1 mounting plate, and 4 screws.

Mounting Plate Type


Grass 830 and 831 hinges were discontinued by the manufacturer and are no longer available. This page will show you how to replace your obsolete Grass hinges with new Compact 33 hinges and new mounting plates.

Information on Grass 830 & 831 Hinges

  • Grass 830 hinges were for 5/8" thick doors and open 120 degrees.
  • Grass 831 hinges were for 3/4" thick doors and open 105 degrees.
  • Both hinges had a 35mm cup diameter.
  • Both hinges had a 1/8" bore distance

Replacing Grass 830 & 831 Hinges Using Compact 33 Hinges

  • The Blum Compact 33 hinge is the replacement for these hinges.
  • The Compact 33 will fit into the same 35mm cup drilled into the back of your door.
  • You will need to redrill the small screw holes. Your old screw holes may be left exposed and may need filling if desired.

How to Order and Select the Correct Compact 33 Mounting Plate

  • For each door that you are working on you will need to order 2 new Compact 33 hinges and 2 new Compact 33 mounting plates. Hinges from different manufacturers articulate differently and mixing different brands of hinges can cause binding. Your existing Grass mounting plates will not work with the new Compact 33 hinges, so be sure to order new mounting plates with your hinges.

There are two methods to choose your replacement mounting plate:

  • Method 1: If there is a number stamped on your current mounting plate, use the chart below called "Grass 830 and 831 Mounting Plate Conversion Chart" and choose the proper mounting plate.
  • Method 2: If there is no number stamped on your mounting plate, first measure your overlay (click here for instructions, also found under the resources tab) and then use the chart below, "Grass 830 and 831 Mounting Plate Conversion Chart", to match up your overlay dimension with the proper new mounting plate.

Frequently Asked Questions

How long does it take to get my hardware once it's been ordered?

The delivery time depends on how far you live from our San Diego warehouse. Generally, your order will reach you in 1 to 5 business days. Shipments do not move on weekends and holidays.

Do you ship merchandise outside the United States?

At this time, we only ship to addresses in the continental United States, Alaska, and Hawaii. For APO/FPO/DPO and Canadian orders, please email with a list of the SKU numbers and quantities you would like to purchase, along with your complete ship to address. Once we receive this information we will email you a shipping quote. Please note: Canadian shipments have a $50.00 minimum order.

I have a hinge that I am trying to replace but I need help identifying it. Can you help?

Yes! Please click here to visit our Hinge Finder page.

Some of your hinges are sold by the each and some sell by the pair. What is the difference?

When the unit of measure says “pair” that means two hinges. Usually you need one pair of hinges per door. When the unit of measure says “each” that means one hinge. You would usually order 2 “each” hinges per door.

I want to replace my hinges. How do I make sure the screw holes on the new hinge match the screw holes on the old hinge so I do not have to redrill the holes?

Unfortunately, hinge manufacturers have never standardized the location of their screw hole patterns. Every manufacturer puts their screw holes in a slightly different place. This means that when you replace hinges you will almost certainly have to do some filling and redrilling. The exception to this is Architectural door hinges which are built to a standardized template for each size hinge.
