SIERRA Undermount Sink Mount Kit – Single Kit, Mounts One Sink
SIERRA Undermount Sink Mount Kit – Single Kit, Mounts One Sink
The SIERRA Undermount Sink Mount Kit is one bagged kit of four Z clips, four 1 in. waffle-back stud fasteners, four wing nuts and four flat washers: everything needed to hang one undermount sink at four points.
The waffle-back studs bond to the underside of the countertop with a fast-set anchoring adhesive, so nothing is drilled through the slab and no hardware shows on the finished top. Once the adhesive has set, seat the sink, hook the Z clips over the rim and tighten each point by hand with the washer and wing nut. The same kit also works for anchoring panels.

Frequently Asked Questions
What is in the kit?
The SIERRA Undermount Sink Mount Kit contains four Z clips, four 1 in. waffle-back stud fasteners, four wing nuts and four flat washers, enough to mount one sink.
Do I have to drill through the countertop?
No. The waffle-back studs are bonded to the underside of the top with adhesive, so nothing goes through the slab and the finished surface stays clean.
Is adhesive included?
No. A fast-set bonding or anchoring adhesive is needed to fix the studs and is sold separately.
Why wing nuts rather than plain nuts?
A wing nut can be tightened and adjusted by hand, so the sink can be levelled during the set and re-tensioned later without tools.
