SIERRA Undermount Sink Mount Kit – 50 Kits per Box
SIERRA Undermount Sink Mount Kit – 50 Kits per Box
The SIERRA Undermount Sink Mount Kit is a box of 50 bagged kits, each with 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.
