This guide is based on detailed insights from verified installation instructions and technical notes, tailored to U.S. users seeking precision and clarity in the installation process.
This guide outlines the necessary preparation, tools, alignment techniques, and step-by-step procedures to install Blum Tandem plus Blumotion drawer slides. Emphasis is placed on ensuring accuracy, level installation, and proper use of hardware to maximize performance and longevity.
Overview of Blumotion Drawer Slides
Blum Tandem plus Blumotion drawer slides are designed for full-extension drawers, allowing users to access the entire contents of a drawer easily. These slides are available in different load capacities—such as the 563H for lighter duty and the 569H for heavier loads with a 150 lb. capacity. Each model is designed for specific drawer-side thicknesses, and it is critical to match the hardware to the material used in the drawer construction.
The Tandem design refers to the dual-track system, where each drawer has both front and back slides for enhanced stability. Blumotion technology provides a soft-close feature, reducing the noise and wear associated with slamming drawers.
When purchasing drawer slides, users must ensure they select the correct model based on drawer thickness and load requirements. For example, the 563/569F models are intended for 3/4" drawer sides, whereas the 563/569H models are for 1/2" to 5/8" drawer sides. Confusing these models can lead to improper installation and reduced performance.
Preparation for Installation
Before beginning the installation process, users must gather the necessary tools and materials. Essential tools include a combination square, a level, a tape measure, a power drill with a Phillips-head bit, and a carpenter's square or measuring tape. It is also recommended to have wood scraps or temporary supports to hold the drawer slides in place during installation.
A key step in preparation is to clean the drawer and cabinet surfaces. Any grease or oil on the drawer slides can affect the soft-close mechanism and the overall smoothness of the drawer movement. A dry cloth or paper towel should be used to wipe the slides clean, followed by a quick cleaning with alcohol to remove any residual oils.
Another critical step is to ensure that the drawer is empty and that all components are accounted for. This includes the drawer slides, locking mechanisms (both left and right), and all necessary screws. The locking mechanisms are sold separately and must be ordered in pairs—one for the left and one for the right side of each drawer set.
Users are advised to measure the drawer and cabinet space before beginning installation. Accurate measurements help in aligning the drawer slides correctly, ensuring that the drawer will open and close smoothly without binding or misalignment.
Tools and Materials
The following tools and materials are recommended for installing Blumotion drawer slides:
- Combination square – For setting precise measurements, particularly the 15/16" depth behind the face frame.
- Level – A level of at least 2 inches is necessary for each drawer slide installation to ensure proper alignment.
- Tape measure – Used for accurate measurements of drawer length, slide position, and clearance.
- Power drill with Phillips-head bit – For attaching the drawer slides to the cabinet and drawer sides.
- Carpenter's square or measuring tape – For marking and aligning screw holes and notches.
- Wood scraps or temporary supports – Used to hold drawer slides in place during installation.
- Blum Tandem plus Blumotion drawer slides – Ensure the model matches the drawer thickness and load requirements.
- Locking mechanisms – One left and one right for each drawer set.
- Screws – Specific to the drawer slides and cabinet material.
- Lubricant – A small amount can be added to the corners for smoother movement.
- Sandpaper or file – For smoothing notches and ensuring a clean fit.
Using sharp, well-maintained tools is essential for minimizing errors and ensuring a clean installation. Dull blades or drill bits can lead to inaccurate cuts and screw holes, which may compromise the alignment and stability of the drawer slides.
Installation Steps for Blumotion Drawer Slides
The installation process begins with preparing the cabinet and drawer for the drawer slides. The following steps provide a clear and structured approach to installing Blum Tandem plus Blumotion drawer slides.
Step 1: Install Drawer Slides in Cabinet
Begin by positioning the drawer slides in the cabinet. For cabinets with face-frames, it is necessary to block out the cabinet side so that the drawer slides are flush with the face frame. A combination square set to 15/16" can be used as a reference to ensure consistent placement.
To install the slides, cut temporary wood scraps to support the drawer slides while drilling. These scraps are placed on the opposite side of the cabinet from the drawer slide, providing stability during installation.
For each drawer slide, start with the left side. Place a scrap board on the opposite side and install the right slide to match the left. This method ensures that both sides are aligned correctly, making it easier to install multiple drawers in the same location.
Install the top drawer slides first, as the lower slides may be obstructed by temporary supports used for upper drawers. The Blum instructions recommend installing the drawer slides 15/16" behind the face frame for inset drawers. This positioning is critical for achieving a seamless and flush appearance.
Once the slide is positioned, loosely install one screw in the slotted hole. Hold the combination square in place to confirm the 15/16" depth, then tighten the screw. Adding a second screw above the first provides additional stability and helps prevent the slide from shifting during use.
Step 2: Align and Secure the Drawer Slides
After installing the drawer slides in the cabinet, it is important to check their alignment. Use a level to ensure that the slides are perfectly horizontal. Any tilt or unevenness can cause the drawer to bind or wobble when opened or closed.
If the cabinet has multiple drawers, repeat the installation process for each set of slides, ensuring that each is aligned with the same reference point. This consistency ensures that all drawers will operate smoothly and uniformly.
Once all slides are in place, tighten all screws securely. Avoid over-tightening, as this can strip the screw holes or cause the slides to shift out of alignment.
Step 3: Prepare and Install the Drawer
Before installing the drawer, it must be prepared for the drawer slides. The drawer should be empty and clean, with all grease and oil removed from the slide contact surfaces. A dry cloth or paper towel can be used to wipe the slides, followed by a quick cleaning with alcohol to remove any residual oils.
Place the new drawer slides in the drawer so that the back edge of each slide rests against the inside edges of the front edge of its opposite slide. Ensure that the slides are not installed upside down, as this can affect the soft-close mechanism and the overall movement of the drawer.
Check that all four corners of the drawer are pressed firmly into their corresponding slots on both sides of the drawer. If necessary, add a few drops of lubricant to each corner’s hole to ensure smooth movement.
Before finalizing the installation, ensure that no parts have become loose during the process. If any components are loose, make the necessary adjustments before proceeding.
Step 4: Attach the Drawer to the Cabinet
With the drawer prepared and the slides installed in the cabinet, it is time to attach the drawer to the cabinet. Carefully slide the drawer into place, ensuring that the slides align correctly with the cabinet-mounted slides. The drawer should move smoothly and evenly without resistance.
Once the drawer is in place, secure it using the locking mechanisms. These must be installed on both the left and right sides of the drawer. Follow the manufacturer’s instructions for attaching the locking devices, ensuring that they are positioned correctly and securely fastened.
After installation, test the drawer by opening and closing it several times. The soft-close feature should engage smoothly, and the drawer should remain level and stable throughout its range of motion. If the drawer does not operate smoothly, check the alignment of the slides and make any necessary adjustments.
Troubleshooting Common Issues
During or after installation, users may encounter issues that affect the performance of the drawer slides. Common problems include misalignment, uneven movement, and resistance when opening or closing the drawer.
Misalignment is often caused by inaccurate measurements or improper leveling. To correct this, recheck the positioning of the drawer slides in the cabinet and drawer. Use a level and combination square to realign the slides as needed.
Uneven movement can occur if the slides are not securely fastened or if the drawer is not properly balanced. Tighten all screws and ensure that the drawer is level and aligned with the cabinet. If the drawer still moves unevenly, consider adjusting the locking mechanisms or adding lubricant to the corners.
Resistance or binding can be caused by dirt, debris, or excess lubricant. Clean the slides thoroughly with a dry cloth and alcohol, and reapply a small amount of lubricant if necessary. If the issue persists, check the slides for damage or wear and replace them if needed.
Maintenance and Care
To ensure the long-term performance of Blumotion drawer slides, regular maintenance is recommended. Clean the slides periodically to remove dust and debris, and inspect them for signs of wear or damage. If the soft-close feature becomes less effective over time, a small amount of lubricant can be applied to the corners to restore smooth operation.
Avoid using excessive force when opening or closing the drawer, as this can strain the slides and reduce their lifespan. If the drawer becomes difficult to open or close, check for misalignment or resistance and make the necessary adjustments.
By following these maintenance tips, users can extend the life of their Blumotion drawer slides and ensure continued smooth and quiet operation.
