Assess Mounting Application
and Measure Cabinet Opening
Before attempting to mount your Blum®Tandem Edge drawer
slides, you need to know whether your cabinets are frameless
or have face frames. This will affect the mounting specifications.
You also need to make sure you have the right length of slides
for your installation. Measure the height, width and depth of the
opening into which the drawer will be installed. Note that the
inside cabinet depth is the distance from the front of the cabinet
side or face frame to the cabinet back.
Refer to Table 1 to determine the inside cabinet depth and
runner setback specifications for your particular application.
Check Drawer Specifications
Blum®Tandem Edge drawer slides require very specific drawer
dimensions. As a result, these slides are not recommended
for retrofit applications. Build your drawer so that it conforms
to the specifications shown in Fig. 1. Pay particular attention to
the required inside drawer width, the required clearances around
the drawer box and the recess required under the drawer bottom.
If your drawer is not sized according to the specifications,
you will not be able to use Blum®Tandem Edge slides.
Prep the Drawer
Once you have a drawer sized to work with Blum®Tandem Edge
slides, you need to modify the drawer back to accept the slides
and install the locking mechanisms on the drawer bottom.
1. Cut 13⁄8" wide x 1/2" deep notches in the bottom corners of
the drawer back (beneath the drawer bottom) to accommodate
the slides. The notches need to be flush with the drawer sides
and bottom. Fig. 2.
2. Drill 6mm diameter x 13/32" (10mm) deep holes in the back
of the drawer at the locations shown in Fig. 2 to accommodate
the hooks on the back of the slides’ runners.
Blum® Tandem Edge drawer slides are
intended for use in overlay drawer-front applications. If
you need to install drawer slides in inset applications, we
recommend using the regular Blum® Tandem Slides.

3. Attach the Locking Devices to the front corners on the
underside of the drawer. The Locking Devices aren’t
interchangeable, so be sure to get them in the appropriate
corners. (The orange plastic piece that can be compressed
should face the middle of the drawer.) Use the screws
provided, taking note that they need to be driven
at a slight angle.
Install the Runners in the Cabinet
If you are mounting to a cabinet that has face frames, you will
need to add blocking to the cabinet sides or use the rear-mount
brackets that came with your slides. Either way, it is crucial that
the slide runners be mounted square to the cabinet opening,
parallel to each other and level.
1. Position one drawer slide runner at the desired height on the
appropriate side of the cabinet, setting it back 5/32" from the
front edge of the cabinet face. If the cabinet has a face frame,
rest the front of the slide on the face frame cross rail.
2. Make sure the drawer slide runner is level from front to back.
If mounting directly to the cabinet side or to blocking that
extends the length of the runner, attach the runner initially
with screws in at least two of the elongated holes. If mounting
to a face frame cabinet using the rear-mount brackets, attach
the runner to the face frame with a screw in one of the front
holes (making sure to maintain the 5/32" setback) and then
attach the rear bracket to the cabinet back initially by driving
a screw in each of the elongated holes. The elongated holes
allow adjustments to be made after a test fit of the drawer
and before installing all mounting screws.
3. Repeat Steps 1-2 for other drawer slide runner.
4. Test fit the drawer: Extend the runners fully and place the
drawer on the runners, making sure the hooks on the back of
the runners fit into the holes you drilled in the back of the
drawer. Push the drawer closed; the Locking Devices will
automatically engage with the runners.
5. Check the drawer’s closed position and note any adjustments
that need to be made on each side. Open the drawer and
remove it by squeezing the orange handles on the Locking
Devices and pulling the drawer straight up and out.
6. If necessary, nudge the slide runners forward or backward
and, if you are using the rear-mount brackets, slide the
brackets up or down to achieve the necessary adjustment.
Then secure the runners in their final position by driving
screws in the locations shown in Figs. 3 and 4.
Depending on the drawer material,
you might need to drill pilot holes before installing the
Locking Devices.
Blum® Tandem Edge slides are “handed”
slides, meaning that one set of runners is for the left side
of the drawer/cabinet and one is for the right. Be sure to
determine the correct orientation before attempting to install.
If you are installing slides in a face frame
cabinet without blocking that extends all the way to the
back, you should fit the rear-mount brackets on the rear of
the slide runners before proceeding further.
Slide runners must be attached with
screws in locations highlighted in Figs. 3 and 4 to achieve
the specified load capacities.
