We Notch and drill supply and install most brands of undermount drawer slides.
Note: Under-mount hardware is mounted underneath the drawer and is not visible from the side when the drawer is open. In order to install the hardware on the drawer, the drawer must be notched through the back beneath the bottom to receive the slide and holes need to be drilled for the pin and the locking devices.

Guidelines for using undermount drawer slides
Each manufacturer has different specifications and results can vary from one model to the next
Any time a new model or application of drawer slide is used, a trial installation is recommended to check the tolerances and determine the setback from the front of the cabinet
Different drawer thicknesses require different drawer widths and lengths and can effect mounting locations of the hardware in the cabinet.
When using pull-outs with a thicker front , the length of the drawer is also different
Some models are better suited for face frame installation than others because some have available rear mounting brackets and some can attach to the face frame, others do not.
Under-mount hardware uses up at least 1/2" of space below the drawer itself
Drawer bottom placement is always critical when using under-mount hardware
Special screws are often required for mounting the slides to the cabinet
Some models have more adjustability than others, up, down, side, in, or out.
Under-mount hardware extends past the back of the drawer by at least 1/2", So be sure to allow enough clearance in the cabinet behind the drawer for the hardware
Locking mechanisms can usually be purchased separately from the slides and can be installed by Western Dovetail.
Western Dovetail can Notch, Drill and Install locking Mechanisms on all of your drawers. Western Dovetail also stocks the full line of Blum Tandem slides including the Blum TANDEM with Blumotion smooth closing feature.
