In today’s kitchens, countertop space is a precious commodity. Whether you live in a cozy apartment, a compact RV, or simply crave a clutter-free cooking environment, every inch matters. Imagine a world where your can opener doesn’t take up valuable real estate, yet is always there when you need it. This is precisely the promise of the Black+Decker under cabinet can opener, a clever solution designed to maximize efficiency and streamline your kitchen workflow.

Choosing the Best Under Cabinet Can Opener: What You Need to Know
Selecting the right can opener can transform a mundane chore into a seamless task. While manual and electric countertop models have their place, under cabinet can openers offer unique advantages that make them a standout choice for many households.
Types of Can Openers: Why Under Cabinet Stands Out
Can openers come in several forms, each with its own set of characteristics. Manual can openers are simple, portable, and don’t require electricity, but demand physical effort. Electric countertop models offer hands-free operation and speed, but can be bulky and consume valuable counter space.
The under cabinet electric can opener, like the Black+Decker Spacemaker series, distinguishes itself by being a permanently mounted, electric appliance. This category typically features automatic, hands-free operation, often with additional functionalities like knife sharpeners and bottle openers. Their main appeal lies in their ability to free up countertops, providing an uncluttered look and making everyday tasks more convenient. While they require a fixed installation, this initial effort is often outweighed by the long-term benefits of an organized and efficient kitchen.
Essential Factors When Buying an Under Cabinet Can Opener
When investing in an under cabinet can opener, several key factors will influence your satisfaction and the opener’s longevity.
- Material and Durability: Look for sturdy construction, often a combination of durable plastic housing and robust metal cutting components. The quality of the blade and drive wheel is paramount for consistent, smooth operation over time.
- Ease of Use & Cleaning: A truly great can opener should offer hands-free operation, automatically piercing and cutting the can without manual intervention. Consider models with automatic shutoff for added convenience. For cleaning, assess how easily the cutting mechanism can be wiped down. Some designs might make it harder to clean if liquids splash.
- Safety Features: Automatic shutoff and secure can gripping mechanisms are important safety aspects, preventing accidents and ensuring smooth operation.
- Installation Requirements: This is a critical consideration for under cabinet models. Verify if your cabinets have a flat underside or if they have a lip or molding. Many under cabinet can openers, including the Black+Decker Spacemaker, are specifically designed for flat-bottom cabinets. If your cabinets have a lip, you might need to use spacers or make modifications for a proper and stable installation.
- Additional Functions: Many under cabinet can openers are multi-functional. The Black+Decker Spacemaker models, for instance, often include a built-in knife sharpener and a bottle opener, further enhancing their value and versatility.
- Price: While price shouldn’t be the sole determinant, consider it in relation to the features, brand reputation, and perceived durability. A slightly higher investment often translates to better performance and a longer lifespan.
Comparing Top Under Cabinet Can Opener Brands
While several brands offer under cabinet can openers, Black+Decker has long been a prominent name in this niche, particularly with its “Spacemaker” line. Their models, like the CO100B or CO100WM, are widely recognized for their integrated design and multi-purpose functionality.
The Black+Decker Spacemaker series stands out for its hands-free operation, automatic shutoff, and compact design that fits seamlessly under most cabinets, provided the cabinet underside is flat. Users appreciate the added convenience of a built-in knife sharpener and bottle opener, making it a true kitchen multi-tool. However, a recurring point in user feedback relates to the installation process. While designed for easy mounting, the requirement for a perfectly flat cabinet bottom means that homes with decorative molding or cabinet lips may require additional effort or custom spacers to achieve a secure and flush fit. Some users have also noted concerns regarding the perceived flimsiness of certain plastic components. Despite these installation nuances, the Black+Decker Spacemaker remains a popular choice for those looking to declutter their countertops and benefit from its integrated features.

Installation Guide: Mounting Your Black+Decker Spacemaker Can Opener
Proper installation is key to the performance and safety of your under cabinet can opener. Here’s a step-by-step guide, with a critical note on cabinet compatibility:
- Gather Your Tools: You’ll typically need a drill, a screwdriver (often a Phillips head), and possibly a pencil for marking. The Black+Decker Spacemaker usually comes with mounting screws and a template.
- Choose the Location: Select a suitable spot under your kitchen cabinet. Ensure it’s near an electrical outlet and provides ample clearance for the can opener itself and for cans of various sizes to be easily placed and removed. Most importantly, verify that the underside of your cabinet is flat and free of any decorative molding or lips.
- Mark Mounting Points: Use the provided mounting template (if available) or hold the can opener in place. Mark the exact locations where the screws will go on the underside of the cabinet.
- Drill Pilot Holes: Using a drill bit slightly smaller than the diameter of your mounting screws, drill small pilot holes at the marked locations. This prevents wood splitting and makes screwing easier.
- Secure the Unit: Align the can opener with the pilot holes and secure it firmly using the provided mounting screws. Ensure the unit is snug and stable before use.
- Addressing Cabinet Lips/Molding: This is where many users encounter challenges. If your cabinet has a decorative lip or molding that prevents a flush mount, you will need to create or acquire spacers to fill this gap. You may also need to slightly modify the molding itself, though this requires more advanced DIY skills. Without a flush mounting, the opener may not function correctly or securely. Pay attention to the location of mounting holes relative to the front edge of the cabinet, as some designs can make it difficult to remove the cutting blade for cleaning if mounted too far back.
Operating and Maintaining Your Under Cabinet Can Opener
Once installed, using and maintaining your Black+Decker Spacemaker is straightforward.
How to Use:
- Prepare the Can: Ensure the can is clean and free of dents around the rim.
- Position the Can: Lift the can opener’s lever. Position the can so its rim is securely seated against the cutting blade and the drive wheel.
- Engage the Blade: Firmly lower the lever. The cutting blade will pierce the can lid, and the opener will automatically start rotating the can.
- Hands-Free Operation: The can opener will continue to rotate the can until the lid is fully cut. It will then shut off automatically.
- Remove the Can and Lid: Lift the lever to release the can. The lid will typically remain attached to a magnetic holder for easy, mess-free disposal.
Cleaning Tips:
- Always unplug the unit before cleaning.
- Wipe the exterior with a damp cloth.
- For the cutting assembly, use a damp cloth or sponge to remove food particles. Some models allow for the cutting blade to be removed for more thorough cleaning, but as noted, mounting location can sometimes impede this.
- Address any liquid splashes immediately to prevent residue buildup.
Troubleshooting Common Issues:
- Can Not Opening: Ensure the can is properly seated against the blade and drive wheel, and the lever is fully lowered. Check for any obstructions.
- Lid Getting Stuck: Sometimes the lid might not detach cleanly. Gently lift the lever and remove the can. If the magnet is too strong, a slight twist or tap can help release the lid.
- Unit Not Starting: Check if the unit is plugged in securely and if the lever is fully engaged.
Where to Purchase Under Cabinet Can Openers
Black+Decker Spacemaker under cabinet can openers are widely available. You can typically find them at major retailers specializing in home goods and electronics, such as Walmart, Amazon, Target, and various online appliance stores.

Tips and Tricks for Maximizing Your Under Cabinet Can Opener
Beyond basic operation, a few tips can help you get the most out of your Black+Decker Spacemaker can opener.
Opening Different Can Sizes and Types
The Black+Decker Spacemaker is designed to handle a wide range of can sizes, from standard soup cans to taller varieties. Ensure the can is positioned upright and stable before engaging the cutting mechanism. For very tall cans, confirm there’s enough vertical clearance beneath your cabinet. Always inspect cans for severe dents around the rim, as these can hinder proper engagement and cutting.
Keeping Your Can Opener Clean and Functional
Regular, light cleaning is more effective than infrequent deep cleaning. A quick wipe-down after each use, especially if any liquid has splattered, will prevent food residue from hardening. For the cutting blade, use a small brush or a damp cloth to clear any debris. If your model allows, removing the blade for a more thorough wash can extend its sharpness and hygiene. Be mindful of the area directly beneath the opener, as splashes can occur.
Handling Stuck Cans or Operational Glitches
If a can gets stuck or the opener stops mid-way, first unplug the unit for safety. Gently try to release the can by wiggling it or manually lifting the lever. Often, it’s a matter of minor misalignment. If the unit struggles to cut, check the blade for any dullness or obstruction; while not user-replaceable, a clean blade performs better. If you frequently encounter issues, review the installation to ensure the unit is mounted securely and level, as this can impact its cutting efficiency.
Conclusion
The Black+Decker under cabinet can opener offers a compelling solution for modern kitchens seeking efficiency and organization. By reclaiming valuable countertop space and providing multi-functional capabilities, it streamlines daily tasks and contributes to a clutter-free environment. While installation considerations, particularly for cabinets with molding, require careful attention, the hands-free operation and convenience it provides make it a worthwhile addition for many homes.
