LAMINATE
Treston laminate tops assembled with wood screws provided.
PHENOLIC
DO NOT USE provided screws from the hardware pack provided with the table. These screws are for
laimate work surfaces only.
Treston phenolic tops can be assembled in 2 ways:
• Mechanical fasteners - Screws to be provided by the installer. Pre-drill a pilot hole in the bottom of the work
surface, taking care to keep from penetrating through the top. The pre-drilled hole should be the same length as
the screw shaft. The screw should be slightly larger in diameter than the pilot hole. Use a coarse threaded screw,
wood or machine.
• Adhesive - Provided by the installer. Use 100% silicon. Apply several “spots” or a continuous bead to the top of
the table frame. Position the work surface as centered on the frame and let cure for 12 hrs at room temp.

STEP ONE: Lay rear case assembly with back side
down. Attach depth kit rails to the legs with the work
surface support lips facing up, flush with the inside of the
leg. Attach the depth kit components using M8 hardware,
inserting threaded nut plate into legs.
NOTE: Wait to attach lower depth kit rails until step 3,
after telescoping legs have been inserted.
STEP FOUR: Attach lower depth kit rails to legs
using M8 hardware. Insert the threaded nut plate into
telescoping leg. M8 bolts with washers will hold depth kit
rail, leg tube and telescoping leg together.
STEP THREE: If using leg covers, slide them in BEFORE
attaching the bottom part of the legs.
STEP SIX: Attach front leg/front rail assembly to the
rest of the frame with M8 hardware and nut plates. Insert
telescoping legs into leg tubes before attaching lower
depth kit rails. (see steps 1-4). Tighten all bolts.
STEP TWO: Insert telescoping legs into leg tubes. Align
holes with outer side of the leg tubes. Set to desired
position/height of the table - remember to include glides
and work surface in total height.
STEP FIVE: With rear case still laying flat on the floor,
lay front leg and front rail assembly onto depth kit rails,
keeping the depth kit rails flush with the outsides of the
front assembly.

STEP SEVEN: Insert glide into bottom of telescoping leg
tubes. Attach second nut to glide stem and tighten. (In the
above photo, the glide is placed in the shortest position.) If
using casters, glide hardware is not needed.
STEP EIGHT: If using leg covers, slide them down at this
point.
STEP NINE: Rotate table into upright position. If
attaching a drawer unit, attach the drawer bracket rail at
this point (ordered separately).
STEP TEN: Attach laminate work surface using wood
screws provided.
*If using a phenolic top, 100% silicon adhesive is
recommended in place of drilling holes for screws.
**Provided wood screws are for laminate work surfaces
>25mm. DO NOT USE PROVIDED WOOD SCREWS
FOR 3/4” PHENOLIC TOPS.
