Weight Rating

  • Door opening angle is 107 degrees.
  • The Blum Aventos Stay Lift System is ideal for smaller cabinets with lift-up doors (cabinet heights of 7-3/8" to 15-3/4" and cabinet widths of 15" to 39").
  • Uses Blum's Blumotion soft-close technology to softly and quietly close the door.
  • Can be installed on cabinets with either overlay doors or inset doors.
  • Fasteners and a gray plastic cover (not shown in photo)are included with the purchase. Door and cabinet shown in image are not included.
  • This product is sold by the pair. Order one pair per door you are installing.
  • Mounting plates are mandatory and sold separately, you can purchase them HERE.


  • The Blum Aventos HK-S is easy to adjust and install.
  • Instructions are included with purchase.
  • We recommend that you download and print out the much more complete PDF Instructions at the document found under Downloads.
  • Works on both face frame and frameless cabinets. For face frame cabinets, it is necessary to install a wooden mounting block behind and flush with the face frame. This block is not included and must be fabricated by the installer ("blocking out" the face frame).

Choosing a Model

  • There are three models available. Choose your model depending on the size and weight of your door.
  • Calculate the "Power Factor" of your door using the following:
    • Weight of door in pounds (Door Weight). The weight of the door must include double the weight of any cabinet knob or pull that is going to be attached to the door. So if the door weighs 10 lbs and your cabinet pull weighs 1/4 lb your Door Weight equals 10 lbs plus double the cabinet pull weight (1/2 lb) for a total of 10.5 lbs.
    • Cabinet Height in inches (Door Height)
  • Calculate the "Power Factor" by multiplying the Door Weight times the Cabinet Height. Sample Calculation:
    • Door Weight is 10 lbs
    • Cabinet Height is 15 inches
    • Door Pull or Knob Weight is 0.25 lbs
    • Calculation: [10+ (2 x 0.25)] x 15 = 157.5
  • For a Power Factor of from 19 to 39 use the lightweight model (Blum #20K2B00.NA / SKU 268045) Note this model is meant for the smallest sized doors. Because of this, only one of the arms is powered. The second arm is free-swinging. This is normal and not a defect.
  • For a Power Factor of from 40 to 85 use the medium weight (Blum #20K2C00-NA / SKU 268046)
  • For a Power Factor of from 86 to177 use the heavy weight model (Blum #20K2E00-NA / SKU 268047)
  • Optional Item: A restriction clip is available that restricts the normal 107 degree opening angle to 75 degrees. This is useful for high doors where it might be difficult to reach the door handle. Also useful if the door hits something above it when in the full 107 degree open position.

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.
