THE INSTALLATION OF ANY 
TOPMOUNT-STYLE SINK
Determine the locations for the clip brackets around 
the perimeter of the sink. Pre-drill holes for the 
clips using appropriate methods for the countertop 
material.
Clean the surfaces of the sink and countertop which 
will meet, with denatured alcohol.
Evenly apply a bead of silicone along perimeter edge 
of the opening on the top of the countertop.
Carefully align the sink over the countertop opening.
Evenly apply pressure to the sink securing a seal of 
silicone against the countertop.
Verify the sink is evenly aligned with the countertop. 
Attach and tighten the clip brackets against the edge
of the sink. Do not tighten one screw completely 
before others. Partially tighten one clip then the one 
across from it, and so on until all clips are fully
tightened. This will safeguard against an uneven or 
insecure installation.
Use a cloth with denatured alcohol along the 
perimeter of the sink and countertop to remove any 
excess sealant.

Due to the nature of the T3121L clip system please cut

TOPMOUNT TRUGRANITE/QUARTZ SINKS
Every Topmount Trugranite/Quartz sink has pre-
scored holes to accommodate the desired location of 
faucet and accessories. The holes can be located on 
the underside of the faucet deck of the sink. There 
may be yellow-dotted circle labels at the topside to 
help identify where to nd these pre-scored holes. 
Before knocking the holes out, verify the yellow-
dotted circle labels align with the actual location of the 
embossed holes on the underside of the sink. Then, 
carefully knock the holes out from the topside of the 
sink using a screwdriver and hitting it gently with a 
hammer. Use a metal hole saw or jigsaw to enlarge 
the opening if necessary.
