The Tenn-Tex C-319 is a left-hand adjustable undermount bracket designed to mount undermount drawer slides using a 10mm dowel connection point. It gives the left side of the drawer installation a secure, adjustable bearing position without fastening directly through a cabinet side face.
This bracket solves a specific installation scenario: an undermount drawer slide that needs to seat on a pre-bored 10mm dowel hole rather than fastening with screws alone. That setup appears in CNC-drilled production panels and in retrofit installs where a dowel bore is already present. Once the bracket is seated on the dowel, the adjustable feature lets you true up the slide position before locking everything down — a meaningful advantage when you are hanging several drawers in a run and need consistent front reveal across all of them. The left-hand designation means this bracket goes on the cabinet's left interior side as you face the opening; it is not interchangeable with the right-hand version.
The C-319 is a Tenn-Tex Plastics component. The source data does not specify the bracket's material beyond the brand's plastic manufacturing background, and no finish or color is stated in the available attributes. Confirm the physical material and color match your cabinet interior before ordering if appearance inside the cabinet matters on your job.
Cabinet shops running CNC-drilled panel lines will recognize the 10mm dowel bore as the natural home for this bracket — it drops into an existing hole in the panel sequence rather than requiring a separate screw layout. Custom builders and installers doing one-off drawer work also reach for it when a pre-bored panel calls for a dowel-mount component instead of a surface-screw fix. Because it is sold as a single left-hand unit, it suits shops that track left and right components separately in their ordering, or jobs where one side needs replacement without pulling the paired bracket.
Yes. This is the left-hand cabinet-side bracket only. A working undermount installation on one drawer requires a left-hand and a right-hand bracket — order both sides to complete the set.
The bracket seats on a 10mm dowel. Your panel must be drilled to 10mm at the bracket's mounting position before installation.
The C-319 is a Tenn-Tex program component. Compatibility with other brands' undermount slides is not confirmed by the source data — use it within the Tenn-Tex system to be certain of fit.
The source data describes the bracket as adjustable but does not detail the adjustment method. Check the Tenn-Tex installation guide for the C-319 to confirm the tool requirement before starting the install.
Getting the left cabinet member seated accurately and adjustably is the quiet foundation of a drawer run that lines up on the first hang. The C-319 puts that precision on a 10mm dowel bore, which means one less variable when the panel is already drilled and the drawer schedule is full.
